An In-Depth Guide to: How do I Fix my Ledger Nano’s Stuck Ethereum Transaction?!?!?! (It’s Been Stuck for Weeks and NOTHING Traditional has Worked!!!!) As Well as: How Do I Choose My Nonce??? I’ve Tried MetaMask, MEW/MyEtherWallet, and Others, but Nothing is Working Correctly!!! I’m Dying by Stress!

So, if you were like me 1-2 months ago, you’ve probably already gone through 2,or 3, ...or 40 articles and guides that probably say something like:
“YeP, eVeRy EtHeReUm UsEr WiLl EvEnTuAlLy HaVe ThE LoW-gAs ExPeRiEnCe, YoU’rE nOt AlOnE! DoN’t FrEaK OuT tHoUgH; ThErE iS a WaY tO fIx It!”
Chances are, every time you read another useless article, you want to kill the nearest inanimate object, even though it was never alive in the first place. Nonetheless, you’re gonna kill it as much as it can be killed, holding nothing back; or, you’re just plotting to and slowly getting closer to executing the plan (and the object) every time you are insulted once again.
However, if you have the ability to download software (MyCryptoWallet) on a PC, it should be safe to relax now. I think you’ve finally found some good news, because I am 99.99...% sure this will work for the issue that so many people are having at this time, around the end of the month of May, year 2020.
More and more people are likely to be having this issue soon, since Ethereum's gas prices have been insanely high lately as well as having 300% price changes in a matter of minutes; Etherscan’s Gas tracker is nearly uselessly-inaccurate at this time. I've heard that there's a congestion attack; that was said a week ago, and it appears to be ongoing... (I can't think of any other suspect besides Justin Sun to blame it on... it must be incredibly expensive to overload the blockchain for this long... I may be wrong though...)
 
Let’s begin
For myself, I was trying to send an ERC20 token when this dreadful issue attacked. Specifically, the token was either BSOV or GRT; I sent them 1 after the other and the first succeeded, and the second one took over a week.
(They’re both great tokens in my opinion and deserve much more attention than they’ve been getting. BSOV is nearing its 1 year anniversary as I write this, and GRT is still in its 90 day community-development progress test, so of course I'm gonna take this opportunity to "shill" them; they are great tokens with great communities).
I was able to finally fix it, after a week of mental agony (also the txn finally processed 1-2 hours before I found the solution, robbing me of the gratitude of fixing it myself... (╯‵□′)╯︵┻━┻ ...but now I guess I can hopefully save some of you the headaches that I endured... ) I’m providing the ability to do the same, in a step by step guide.
Why did I go through all of this trouble? I'd fault the fact that I have ADHD and autism, which in my case can multiply each other’s intensity and cause me to “hyper-focus” on things, much much more than most with the same qualities, intentionally or not. Adderall is supposed to give me a bit of control over it, but except for in a very-generalized way, it’s still 90% up to chance and my default-capabilities to allow me control over my attention with self-willpower. But also Karma and Moons pls... ʘ‿ʘ
 
  1. In MyCrypto, (I'm using the Windows 10 app, version 1.7.10) you will open to a screen that says "How would you like to access your wallet?". Choose Ledger, of course. (Unless your here for some non-ledger issue? Idk why you would be but ok.)
  2. On the next screen (having your nano already plugged in, unlocked, and opened into the Ethereum app) click "Connect to Ledger Wallet"
  3. A screen overlay should appear, titled: "Select an Address". Here is where it may get confusing for some users. Refer to "AAA" below to know how to find your account. (Geez, sorry lol that was a huge amount of info for a reddit reply; I might've over-elaborated a little bit too much. but hey it's valuable information nonetheless!)
  4. After escaping the "AAA" section, you'll have accessed your account with MyCrypto. Awesome! To find your ERC20 tokens, (slight evil-laughter is heard from an unidentifiable origin somewhere in the back of your mind) go to "AAB".
  5. (You may have decided to find the token(s) on your own, rather than daring to submit to my help again; if so, you may pity those who chose the other path... ~~( ̄▽ ̄)~~) Now, once you've added your token, you should revert your attention to the account's transfer fill-out form!
  6. I'll combine the steps you probably understood on your own, already. Put in the address that your stuck transaction is still trying to send currency to. If an ERC20 token is involved, use the drop-down menu to change "ETH" to the token in trouble. Input your amount into the box labeled... wait for it... "Amount". Click on "+Advanced".
  7. Refer to Etherscan.com for the data you will need. Find the page for your "transaction(txn) hash/address" from the transaction history on the wallet/Ethereum-manager you used to send from. If that is unavailable, put your public address that your txn was sent from into the search tool and go to its info page; you should be able to find the pending txn there. Look to open the "more details" option to find the transaction's "Nonce" number.
  8. Put the nonce in the "Nonce" box on MyCrypto; you will contest the pending txn with a new txn that offers larger gas fees, by using the same nonce. If (but most likely "When") the new transaction is processed first, for being more miner-beneficial, the nonce will then be completed, and the old transaction will be dropped because it requests an invalid, now-outdated nonce. Your account will soon be usable!
  9. Go to the Gas Tracker, and it may or may not provide an informative reading. Choose whatever amount you think is best, but choose wisely; if you're too stingy it may get stuck again, and you'd need to pay another txn's gas to attempt another txn-fix.
  10. At the time I write this, I'd recommend 50-100 gwei; to repeat myself, gas requirements are insane right now. To be safe, make the gas limit a little higher than MCW's automatic calculation, you may need to undo the check-mark for "Automatically Calculate Gas Limit".
  11. Press "Send Transaction"!!!
  12. You will need to validate the action through your nano. It will have you validate three different things if you are moving an ERC20 Token. It's a good idea to verify accuracy, as always.
 
Well, I hope this worked for you! If not, you can let me know in a reply and I'll try to figure it out with you. I like making these in-depth educational posts, so if you appreciate it please let me know; I'll probably make more posts like this in the future!
( Surely this is at least far better than Ledger's "Support" article where they basically just tell you "Yeah, we haven't bothered to make a way to manually select nonces. I guess we might try to make that available for Bitcoin accounts at some point in the future; who knows? lol"... that's not infuriating at all, right?)
 
AAA:
Before I tell you how to find your address, I will first make it clear, within the italicized text, exactly which address you are looking for, if you are not already sure:
You may also skip the text written in italics if your issue does not include an ERC20 token, if you wish.
Ledger Live can confuse some users with its interface. On LL, to manage an ERC20 token, you first must go to your Ethereum account and add the token. When you then click on the added token under "Tokens" below the graph chart for your account's ETH amount over time, the screen will then open a new screen, that looks just the same, except focused on the specific ERC20 token. To confuse users further, there is then an option to "Star account", which then add the ETH icon with the ERC20 token's first letter or symbol overlapping, onto the easy access sidebar, as if it was another account of similar independency to the ETH account it was added to.
This improperly displays the two "accounts" relation to each other.
Your ERC20 holdings (at least for any and all ERC20 that I know of) are "held" in the exact-same address as the Ethereum address it was added to, which also "holds" any Ether you've added to it. You send both Ether (ETH) and any ERC20 Tokens to and from only Ethereum addresses of equivalent capabilities, in both qualities and quantities. In all basic terms and uses, they are the same.
So, to know what the problematic account's address is, find the address of the Ethereum account it was added to in Ledger Live.
Now, to find your address on MyCrypto, the most reliable way to find it, that I am aware of, is this:
Open Ledger Live. Go to the screen of your Ethereum address (again, this is the one that you added your ERC20 token, if applicable. If you're not dealing with an ERC20 token, you may ignore everything I've put in Italics). Click on "Edit account"; this is the icon next to the star that may look like a hex-wrench tool. On the new screen-overlay, you will see "> ADVANCED LOGS". Click on the ">" and it will point down while revealing a drop-down with some data that you may or may not recognize/understand. Likely to be found indented and in the middle-ish area, you will see this line, or something hopefully similar:
"freshAddressPath": "44'/60'/X'/0/0",
The "X" will probably be the only thing that changes, and the actual data will have a number in its place; it will not be a letter. Let's now put that line to use in MyCrypto:
Take the 44'/60'/X'/0/0 , and make sure you DO NOT copy the quotation marks, or that comma at the end either.
You can do this before or after copying and/or pasting, but drop the second "/0" at the end; it was not necessary in my case, I expect that you won't need it either, and will probably just make MyCrypto see it as an invalid input.
Okay, now go back to the "Select an Address" screen-overlay in MyCrypto.
Next to "Addresses", click on the box on the right, and you should be shown a list of options to select from in a drop-down menu.
Scroll all the way down, and you should find the "Custom" option at the very bottom. Select it.
A new box will appear; probably directly to the right of the now-shortened box that now displays the "Custom" option that you just selected. This box will offer an interface for typed input. ...yep... once again, believe it or not, you should click it.
Type " m/ ", no spaces before or after.
Type in or paste the data we retrieved from ledger live.
The box should now hold this:
m/44'/60'/X'/0
Again, X should be a number. In fact, that number is probably equal to the number of Ethereum (not including any ERC20 wannabe) accounts that you've made on Ledger Live before making the one we're working on right now! (1st Eth. Acc. would have: X = 0, 2nd: X = 1, 3rd: X = 2, ...)
Make sure you've included every apostrophe ( ' ), and solidus ( / ); there is NO APOSTROPHE for the "m" at the start and the "/0" at the end!
If you press the enter key or click on the check-mark to the right of where you typed, the appropriate addresses will be generated, and the address you created through Ledger Live should be the first one on the list!
Select your address and press "Unlock", and you are now accessing your account through the MyCrypto app's interface!
 
AAB:
In order to access your ERC20 token, you will need to add them first.
You may have to scroll down, but on the right-side of your unlocked account screen, you'll see a box with "Token Balances" as its header.
Click "Scan for tokens". This may take a short bit of time, and when it's done it may or may not display your ERC20 token. If it worked, you can head on back to the main part.
If you got the result I did, it won't display your token, or, if our result was exactly the same, it won't display any at all. However, you should now have the "Add Custom Token" option available, so see where that takes you.
You should discover four boxes, specified in order (Address/ Decimals / Token_Symbol / Balance). You may only need to fill in the "Address" box, but if you need to fill others, you'll find those with the token's address; here's 2 ways to find it, if you don't already know.
Method I:
Since you've probably already been managing your token with Ledger Live, you can go to the LL screen of your "account" for that token; Right next to the account's icon, and directly above the name, you'll see:
Contract: 0x??????...????????
Yes, go on; click it. You'll find the token's page on Etherscan; this was just a shortcut to the same place that both of the two previously referenced methods lead to. Skip to method... III?
Method II:
Go to Etherscan.com, or a similar Ethereum-blockchain-monitoring website, if you have a different preference. Search for the name of your token, and you should be able to see it as a search result. Activate your search manually of by selecting search option. Continue on with Method III.
Method III (Iⅈ what makes you think there was a third method? I said 2!):
At this point, you should find the "contract address" somewhere on the screen. This is the identity of the creature that breathes life into the token, allowing it to exist within the world of Ethereum. Steal it, and tell MyCrypto that you've left some of "your" tokens in the address of your ledger's Ethereum account. MyCrypto will trust and believe you without any concern or doubt, just by putting "your" contract address in the box for "Address"; it's almost too easy!
Well whaddya know, this one isn't actually too long! Don't tell anyone who may have taken a little longer whilst finding out how to do it themselves, though. There's value in trying to do something on your own, at least at first, so I'll let them think they made the right choice (¬‿¬). But take this star for humbling yourself enough to seek further help when you need it, since that is a very important life skill as well!
(o゜▽゜)o☆
Now, back to the useful stuff at the top...
 
EDIT: A comment below made me realize that this info should be added too. Here is my reply to the comment saying I could just use MetaMask. I said in the title that this guide is for questions where MEW and MetaMask aren’t working, but I guess it’s easy to miss. I used my u/caddark account to respond:
(Using this account because u/caddarkcrypto doesn’t meet the karma/age standards to comment; the post had to be manually approved.)
I guess I didn’t make it entirely clear; sorry:
The target audience for this guide is anyone with a stuck Ethereum transaction that was initiated through Ledger Live AND are experiencing the same difficulties I had encountered while trying to fix this issue for myself.
This wasn’t any regular stuck Ethereum transaction. Apparently before, there was an issue that made a Ledger Nano nearly impossible to connect to MetaMask (which is also Brave Browser’s integrated “crypto wallet” for the desktop version) and/or MEW (also perhaps any other browser wallets made for chrome and/or brave) that I heard was supposed to be fixed in a recent update. It might’ve been mostly patched, idk, but during my experience, (in which I was using the latest version of Ledger Live that is available right now,) that issue still remained.
The really weird part was that it successfully connected to the browser wallets again after I fixed the stuck transaction. At first I thought that somehow the txn was what was bugging the connection. However, later, during no txn issues, I was again unable to connect.
Seeing the same connection error again later, I opened up the MCW app I downloaded the day before, and was going to just use that. While in the process of operating MCW, I suddenly had another idea to try for the browser wallet so I went back to that just to quickly test it.
The browser wallet worked perfectly...
I don’t know how, but I think that somehow, something in MCW’s software, makes the browser wallets work. They don’t work for me without having MCW opened in the background first.
EDIT 2: Markdown decided to stop working after I did the first edit... I might fix it tomorrow... how did that happen though??? What did I do?
EDIT 3: nvm, I'm just fixing it now; I won't get much sleep tonight I guess.

Filecoin | Development Status and Mining Progress

Author: Gamals Ahmed, CoinEx Business Ambassador
https://preview.redd.it/5bqakdqgl3g51.jpg?width=865&format=pjpg&auto=webp&s=b709794863977eb6554e3919b9e00ca750e3e704
A decentralized storage network that transforms cloud storage into an account market. Miners obtain the integrity of the original protocol by providing data storage and / or retrieval. On the contrary, customers pay miners to store or distribute data and retrieve it.
Filecoin announced, that there will be more delays before its main network is officially launched.
Filecoin developers postponed the release date of their main network to late July to late August 2020.
As mentioned in a recent announcement, the Filecoin team said that the initiative completed the first round of the internal protocol security audit. Platform developers claim that the results of the review showed that they need to make several changes to the protocol’s code base before performing the second stage of the software testing process.
Created by Protocol Labs, Filecoin was developed using File System (IPFS), which is a peer-to-peer data storage network. Filecoin will allow users to trade storage space in an open and decentralized market.
Filecoin developers implemented one of the largest cryptocurrency sales in 2017. They have privately obtained over $ 200 million from professional or accredited investors, including many institutional investors.
The main network was slated to launch last month, but in February 2020, the Philly Queen development team delayed the release of the main network between July 15 and July 17, 2020.
They claimed that the outbreak of the Coronavirus (COVID-19) in China was the main cause of the delay. The developers now say that they need more time to solve the problems found during a recent codecase audit.
The Filecoin team noted the following:
“We have drafted a number of protocol changes to ensure that building our major network launch is safe and economically sound.” The project developers will add them to two different implementations of Filecoin (Lotus and go-filecoin) in the coming weeks.
Filecoin developers conducted a survey to allow platform community members to cast their votes on three different launch dates for Testnet Phase 2 and mainnet.
The team reported that the community gave their votes. Based on the vote results, the Filecoin team announced a “conservative” estimate that the second phase of the network test should begin by May 11, 2020. The main Filecoin network may be launched sometime between July 20 and August 21, 2020.
The updates to the project can be found on the Filecoin Road Map.
Filecoin developers stated:
“This option will make us get the most important protocol changes first, and then implement the rest as protocol updates during testnet.” Filecoin is back down from the final test stage.
Another filecoin decentralized storage network provider launched its catalytic test network, the final stage of the storage network test that supports the blockchain.
In a blog post on her website, Filecoin said she will postpone the last test round until August. The company also announced a calibration period from July 20 to August 3 to allow miners to test their mining settings and get an idea of how competition conditions affected their rewards.
Filecoin had announced earlier last month that the catalytic testnet test would precede its flagship launch. The delay in the final test also means that the company has returned the main launch window between August 31 and September 21.
Despite the lack of clear incentives for miners and multiple delays, Filecoin has succeeded in attracting huge interest, especially in China. Investors remained highly speculating on the network’s mining hardware and its premium price.
Mining in Filecoin
In most blockchain protocols, “miners” are network participants who do the work necessary to promote and maintain the blockchain. To provide these services, miners are compensated in the original cryptocurrency.
Mining in Filecoin works completely differently — instead of contributing to computational power, miners contribute storage capacity to use for dealing with customers looking to store data.
Filecoin will contain several types of miners:
Storage miners responsible for storing files and data on the network. Miners retrieval, responsible for providing quick tubes for file recovery. Miners repair to be carried out.
Storage miners are the heart of the network. They earn Filecoin by storing data for clients, and computerizing cipher directories to check storage over time. The probability of earning the reward reward and transaction fees is proportional to the amount of storage that the Miner contributes to the Filecoin network, not the hash power.
Retriever miners are the veins of the network. They earn Filecoin by winning bids and mining fees for a specific file, which is determined by the market value of the said file size. Miners bandwidth and recovery / initial transaction response time will determine its ability to close recovery deals on the network.
The maximum bandwidth of the recovery miners will determine the total amount of deals that it can enter into.
In the current implementation, the focus is mostly on storage miners, who sell storage capacity for FIL.

Hardware recommendations

The current system specifications recommended for running the miner are:
Compared to the hardware requirements for running a validity checker, these standards are much higher — although they definitely deserve it. Since these will not increase in the presumed future, the money spent on Filecoin mining hardware will provide users with many years of reliable service, and they pay themselves many times. Think of investing as a small business for cloud storage. To launch a model on the current data hosting model, it will cost millions of dollars in infrastructure and logistics to get started. With Filecoin, you can do the same for a few thousand dollars.
Proceed to mining
Deals are the primary function of the Filecoin network, and it represents an agreement between a client and miners for a “storage” contract.
Once the customer decides to have a miner to store based on the available capacity, duration and price required, he secures sufficient funds in a linked portfolio to cover the total cost of the deal. The deal is then published once the mine accepts the storage agreement. By default, all Filecoin miners are set to automatically accept any deal that meets their criteria, although this can be disabled for miners who prefer to organize their deals manually.
After the deal is published, the customer prepares the data for storage and then transfers it to the miner. Upon receiving all the data, the miner fills in the data in a sector, closes it, and begins to provide proofs to the chain. Once the first confirmation is obtained, the customer can make sure the data is stored correctly, and the deal has officially started.
Throughout the deal, the miner provides continuous proofs to the chain. Clients gradually pay with money they previously closed. If there is missing or late evidence, the miner is punished. More information about this can be found in the Runtime, Cut and Penalties section of this page.
At Filecoin, miners earn two different types of rewards for their efforts: storage fees and reward prevention.
Storage fees are the fees that customers pay regularly after reaching a deal, in exchange for storing data. This fee is automatically deposited into the withdrawal portfolio associated with miners while they continue to perform their duties over time, and is locked for a short period upon receipt.
Block rewards are large sums given to miners calculated on a new block. Unlike storage fees, these rewards do not come from a linked customer; Instead, the new FIL “prints” the network as an inflationary and incentive measure for miners to develop the chain. All active miners on the network have a chance to get a block bonus, their chance to be directly proportional to the amount of storage space that is currently being contributed to the network.
Duration of operation, cutting and penalties
“Slashing” is a feature found in most blockchain protocols, and is used to punish miners who fail to provide reliable uptime or act maliciously against the network.
In Filecoin, miners are susceptible to two different types of cut: storage error cut, unanimously reduce error.
Storage Error Reduction is a term used to include a wider range of penalties, including error fees, sector penalties, and termination fees. Miners must pay these penalties if they fail to provide reliability of the sector or decide to leave the network voluntarily.
An error fee is a penalty that a miner incurs for each non-working day. Sector punishment: A penalty incurred by a miner of a disrupted sector for which no error was reported before the WindowPoSt inspection.
The sector will pay an error fee after the penalty of the sector once the error is discovered.
Termination Fee: A penalty that a miner incurs when a sector is voluntary or involuntarily terminated and removed from the network.
Cutting consensus error is the penalty that a miner incurs for committing consensus errors. This punishment applies to miners who have acted maliciously against the network consensus function.
Filecoin miners
Eight of the top 10 Felticoin miners are Chinese investors or companies, according to the blockchain explorer, while more companies are selling cloud mining contracts and distributed file sharing system hardware. CoinDesk’s Wolfe Chao wrote: “China’s craze for Filecoin may have been largely related to the long-standing popularity of crypto mining in the country overall, which is home to about 65% of the computing power on Bitcoin at discretion.”
With Filecoin approaching the launch of the mainnet blocknet — after several delays since the $ 200 million increase in 2017 — Chinese investors are once again speculating strongly about network mining devices and their premium prices.
Since Protocol Labs, the company behind Filecoin, released its “Test Incentives” program on June 9 that was scheduled to start in a week’s time, more than a dozen Chinese companies have started selling cloud mining contracts and hardware — despite important details such as economics Mining incentives on the main network are still endless.
Sales volumes to date for each of these companies can range from half a million to tens of millions of dollars, according to self-reported data on these platforms that CoinDesk has watched and interviews with several mining hardware manufacturers.
Filecoin’s goal is to build a distributed storage network with token rewards to spur storage hosting as a way to drive wider adoption. Protocol Labs launched a test network in December 2019. But the tokens mined in the testing environment so far are not representative of the true silicon coin that can be traded when the main network is turned on. Moreover, the mining incentive economics on testnet do not represent how final block rewards will be available on the main network.
However, data from Blockecoin’s blocknetin testnet explorers show that eight out of 10 miners with the most effective mining force on testnet are currently Chinese miners.
These eight miners have about 15 petabytes (PB) of effective storage mining power, accounting for more than 85% of the total test of 17.9 petable. For the context, 1 petabyte of hard disk storage = 1000 terabytes (terabytes) = 1 million gigabytes (GB).
Filecoin craze in China may be closely related to the long-standing popularity of crypt mining in the country overall, which is home to about 65% of the computing power on Bitcoin by estimation. In addition, there has been a lot of hype in China about foreign exchange mining since 2018, as companies promote all types of devices when the network is still in development.
“Encryption mining has always been popular in China,” said Andy Tien, co-founder of 1475, one of several mining hardware manufacturers in Philquin supported by prominent Chinese video indicators such as Fenbushi and Hashkey Capital.
“Even though the Velikoyen mining process is more technologically sophisticated, the idea of mining using hard drives instead of specialized machines like Bitcoin ASIC may be a lot easier for retailers to understand,” he said.
Meanwhile, according to Feixiaohao, a Chinese service comparable to CoinMarketCap, nearly 50 Chinese crypto exchanges are often somewhat unknown with some of the more well-known exchanges including Gate.io and Biki — have listed trading pairs for Filecoin currency contracts for USDT.
In bitcoin mining, at the current difficulty level, one segment per second (TH / s) fragmentation rate is expected to generate around 0.000008 BTC within 24 hours. The higher the number of TH / s, the greater the number of bitcoins it should be able to produce proportionately. But in Filecoin, the efficient mining force of miners depends on the amount of data stamped on the hard drive, not the total size of the hard drive.
To close data in the hard drive, the Filecoin miner still needs processing power, i.e. CPU or GPU as well as RAM. More powerful processors with improved software can confine data to the hard drive more quickly, so miners can combine more efficient mining energy faster on a given day.
As of this stage, there appears to be no transparent way at the network level for retail investors to see how much of the purchased hard disk drive was purchased which actually represents an effective mining force.
The U.S.-based Labs Protocol was behind Filecoin’s initial coin offer for 2017, which raised an astonishing $ 200 million.
This was in addition to a $ 50 million increase in private investment supported by notable venture capital projects including Sequoia, Anderson Horowitz and Union Square Ventures. CoinDk’s parent company, CoinDk, has also invested in Protocol Labs.
After rounds of delay, Protocol Protocols said in September 2019 that a testnet launch would be available around December 2019 and the main network would be rolled out in the first quarter of 2020.
The test started as promised, but the main network has been delayed again and is now expected to launch in August 2020. What is Filecoin mining process?
Filecoin mainly consists of three parts: the storage market (the chain), the blockecin Filecoin, and the search market (under the chain). Storage and research market in series and series respectively for security and efficiency. For users, the storage frequency is relatively low, and the security requirements are relatively high, so the storage process is placed on the chain. The retrieval frequency is much higher than the storage frequency when there is a certain amount of data. Given the performance problem in processing data on the chain, the retrieval process under the chain is performed. In order to solve the security issue of payment in the retrieval process, Filecoin adopts the micro-payment strategy. In simple terms, the process is to split the document into several copies, and every time the user gets a portion of the data, the corresponding fee is paid. Types of mines corresponding to Filecoin’s two major markets are miners and warehousers, among whom miners are primarily responsible for storing data and block packages, while miners are primarily responsible for data query. After the stable operation of the major Filecoin network in the future, the mining operator will be introduced, who is the main responsible for data maintenance.
In the initial release of Filecoin, the request matching mechanism was not implemented in the storage market and retrieval market, but the takeover mechanism was adopted. The three main parts of Filecoin correspond to three processes, namely the stored procedure, retrieval process, packaging and reward process. The following figure shows the simplified process and the income of the miners:
The Filecoin mining process is much more complicated, and the important factor in determining the previous mining profit is efficient storage. Effective storage is a key feature that distinguishes Filecoin from other decentralized storage projects. In Filecoin’s EC consensus, effective storage is similar to interest in PoS, which determines the likelihood that a miner will get the right to fill, that is, the proportion of miners effectively stored in the entire network is proportional to final mining revenue.
It is also possible to obtain higher effective storage under the same hardware conditions by improving the mining algorithm. However, the current increase in the number of benefits that can be achieved by improving the algorithm is still unknown.
It seeks to promote mining using Filecoin Discover
Filecoin announced Filecoin Discover — a step to encourage miners to join the Filecoin network. According to the company, Filecoin Discover is “an ever-growing catalog of numerous petabytes of public data covering literature, science, art, and history.” Miners interested in sharing can choose which data sets they want to store, and receive that data on a drive at a cost. In exchange for storing this verified data, miners will earn additional Filecoin above the regular block rewards for storing data. Includes the current catalog of open source data sets; ENCODE, 1000 Genomes, Project Gutenberg, Berkley Self-driving data, more projects, and datasets are added every day.
Ian Darrow, Head of Operations at Filecoin, commented on the announcement:
“Over 2.5 quintillion bytes of data are created every day. This data includes 294 billion emails, 500 million tweets and 64 billion messages on social media. But it is also climatology reports, disease tracking maps, connected vehicle coordinates and much more. It is extremely important that we maintain data that will serve as the backbone for future research and discovery”.
Miners who choose to participate in Filecoin Discover may receive hard drives pre-loaded with verified data, as well as setup and maintenance instructions, depending on the company. The Filecoin team will also host the Slack (fil-Discover-support) channel where miners can learn more.
Filecoin got its fair share of obstacles along the way. Last month Filecoin announced a further delay before its main network was officially launched — after years of raising funds.
In late July QEBR (OTC: QEBR) announced that it had ceded ownership of two subsidiaries in order to focus all of the company’s resources on building blockchain-based mining operations.
The QEBR technology team previously announced that it has proven its system as a Filecoin node valid with CPU, GPU, bandwidth and storage compatibility that meets all IPFS guidelines. The QEBR test system is connected to the main Filecoin blockchain and the already mined filecoin coin has already been tested.
“The disclosure of Sheen Boom and Jihye will allow our team to focus only on the upcoming global launch of Filecoin. QEBR branch, Shenzhen DZD Digital Technology Ltd. (“ DZD “), has a strong background in blockchain development, extraction Data, data acquisition, data processing, data technology research. We strongly believe Filecoin has the potential to be a leading blockchain-based cryptocurrency and will make every effort to make QEBR an important player when Mainecoin mainnet will be launched soon”.
IPFS and Filecoin
Filecoin and IPFS are complementary protocols for storing and sharing data in a decentralized network. While users are not required to use Filecoin and IPFS together, the two combined are working to resolve major failures in the current web infrastructure.
IPFS
It is an open source protocol that allows users to store and transmit verifiable data with each other. IPFS users insist on data on the network by installing it on their own device, to a third-party cloud service (known as Pinning Services), or through community-oriented systems where a group of individual IPFS users share resources to ensure the content stays live.
The lack of an integrated catalytic mechanism is the challenge Filecoin hopes to solve by allowing users to catalyze long-term distributed storage at competitive prices through the storage contract market, while maintaining the efficiency and flexibility that the IPFS network provides.
Using IPFS
In IPFS, the data is hosted by the required data installation nodes. For data to persist while the user node is offline, users must either rely on their other peers to install their data voluntarily or use a central install service to store data.
Peer-to-peer reliance caching data may be a good thing as one or multiple organizations share common files on an internal network, or where strong social contracts can be used to ensure continued hosting and preservation of content in the long run. Most users in an IPFS network use an installation service.
Using Filecoin
The last option is to install your data in a decentralized storage market, such as Filecoin. In Filecoin’s structure, customers make regular small payments to store data when a certain availability, while miners earn those payments by constantly checking the integrity of this data, storing it, and ensuring its quick recovery. This allows users to motivate Filecoin miners to ensure that their content will be live when it is needed, a distinct advantage of relying only on other network users as required using IPFS alone.
Filecoin, powered by IPFS
It is important to know that Filecoin is built on top of IPFS. Filecoin aims to be a very integrated and seamless storage market that takes advantage of the basic functions provided by IPFS, they are connected to each other, but can be implemented completely independently of each other. Users do not need to interact with Filecoin in order to use IPFS.
Some advantages of sharing Filecoin with IPFS:
Of all the decentralized storage projects, Filecoin is undoubtedly the most interested, and IPFS has been running stably for two years, fully demonstrating the strength of its core protocol.
Filecoin’s ability to obtain market share from traditional central storage depends on end-user experience and storage price. Currently, most Filecoin nodes are posted in the IDC room. Actual deployment and operation costs are not reduced compared to traditional central cloud storage, and the storage process is more complicated.
PoRep and PoSt, which has a large number of proofs of unknown operation, are required to cause the actual storage cost to be so, in the early days of the release of Filecoin. The actual cost of storing data may be higher than the cost of central cloud storage, but the initial storage node may reduce the storage price in order to obtain block rewards, which may result in the actual storage price lower than traditional central cloud storage.
In the long term, Filecoin still needs to take full advantage of its P2P storage, convert storage devices from specialization to civil use, and improve its algorithms to reduce storage costs without affecting user experience. The storage problem is an important problem to be solved in the blockchain field, so a large number of storage projects were presented at the 19th Web3 Summit. IPFS is an important part of Web3 visibility. Its development will affect the development of Web3 to some extent. Likewise, Web3 development somewhat determines the future of IPFS. Filecoin is an IPFS-based storage class project initiated by IPFS. There is no doubt that he is highly expected.

Bull market is back… Another wave of hacker attacks starts again?

Bull market is back… Another wave of hacker attacks starts again?

The picture from COINDESK related reports
On Aug. 2, Ethereum Classic Labs (ETC Labs) made an important announcement on ETC blockchain. ETC Labs said due to network attack, Ethereum Classic suffered a reorganization on August 1st. This has been the second attack on the Ethereum Classic Network this year.
Did renting-power cause the problem again?
In this ETC incident, one of the miners mined a large number of blocks offline. When the miner went online, due to its high computing power, and some versions of mining software did not support large-scale blockchain mergers, the consensus failed. Therefore, the entire network was out of sync, which produced an effect similar to a 51% attack. Finally, it caused the reorganization of 3693 blocks, starting at 10904147. The deposit and withdrawal between the exchanges and mining pools had to be suspended for troubleshooting during this period.
Media report shows that the blockchain reorganization may be caused by a miner (or a mining pool) disconnected during mining. Although it has been restored to normal after 15 hours of repair, it does reflect the vulnerability of the Proof of Work (PoW) network: once the computing power of the network is insufficient, the performance of one single mining pool can affect the entire network, which is neither distributed nor secure for the blockchain. Neither does it have efficiency.
At present, most consensus algorithms of blockchains are using PoW, which has been adopted over 10 years. In PoW, each miner solves a hashing problem. The probability to solve the problem successfully is proportional to the ratio of the miner’s hash power to the total hash power of mainnet.
Although PoW has been running for a long time, the attack model against PoW is very straightforward to understand, and has attracted people’s attention for a long time: such an attack, also known as double-spending attack, may happen when an attacker possesses 51% of the overall network hash power. The attacker can roll back any blocks in the blockchain by creating a longer and more difficult chain and as a result, modify the transaction information.
Since hash power can be rented to launch attacks, some top 30 projects have suffered from such attacks. In addition to this interference, the main attack method is through the computing power market such as Nice Hash. Hackers can rent hashpower to facilitate their attacks, which allows the computing power to rise rapidly in a short time and rewrite information. In January of this year, the Ethereum Classic was attacked once, and it was also the case that hackers can migrate computing power from the fiercely competitive Bitcoin and Ethereum, and use it to attack smaller projects, such as ETH Classic.

The picture shows the cost of attacking ETH Classic. It can be seen that it costs only $6,634 to attack ETH Classic for one hour.
The security of one network is no longer limited by whether miners within the main net take more than 51% of the total hash power, rather it is determined by whether the benevolent (non-hackers) miners take more than 51% of the total hash power from the pool of projects that use similar consensus algorithm. For example, the hash power of Ethereum is 176 TH/s and that of Ethereum Classic is 9 TH/s. In this way, if one diverts some hash power from Ethereum (176 TH/s) to Ethereum Classic, then one can easily launch a double-spending attack to Ethereum Classic. The hash power ratio for this attack between the two projects is 9/176 = 5.2%, which is a tiny number.

https://preview.redd.it/qj57vgmgb9f51.png?width=699&format=png&auto=webp&s=39c1efc3645f268dbf1c73e1b373d532d5461006
As one of the top 30 blockchain projects, Ethereum Classic has been attacked several times. Therefore, those small and medium-sized projects with low hash power and up-and-coming future projects are facing great potential risks. This is the reason that many emerging public chain projects abandon PoW and adopt PoS.
Proof of Stake (PoS) can prevent 51% attack but has problems of its own
In addition to PoW consensus, another well-adopted consensus algorithm is Proof of Stake (PoS). The fundamental concept is that the one who holds more tokens has the right to create the blocks. This is similar to shareholders in the stock market. The token holders also have the opportunities to get rewards. The advantages of PoS are: (i) the algorithm avoids wasting energy like that in PoW calculation; and (ii) its design determines that the PoS will not be subjected to 51% hash power attack since the algorithm requires the miner to possess tokens in order to modify the ledger. In this way, 51% attack becomes costly and meaningless.

https://preview.redd.it/rf65o1vhb9f51.png?width=685&format=png&auto=webp&s=9d7a9f9dab6ce823a224e91afa9d116310cf27e1
In terms of disadvantages, nodes face the problem of accessibility. PoS requires a permission to enter the network and nodes cannot enter and exit freely and thus lacks openness. It can easily be forked. In the long run, the algorithm is short of decentralization, and leads to the Matthew effect of accumulated advantages whereby miners with more tokens will receive more rewards and perpetuate the cycle.
More importantly, the current PoS consensus has not been verified for long-term reliability. Whether it can be as stable as the PoW system is yet to be verified. For some of the PoW public chains that are already launched, if they want to switch consensus, they need to do hard fork, which divides communities and carries out a long consensus upgrade and through which Ethereum is undergoing. Is there a safer and better solution?
QuarkChain Provide THE Solution: High TPS Protection + PoSW Consensus
For new-born projects, and some small or medium-sized projects, they all are facing the problem of power attack. For PoW-based chains, there are always some chains with lower hash power than others (ETC vs. ETH, BCH vs BTC), and thus the risk of attack is increased. In addition, the interoperability among the chains, such as cross-chain operation, is also a problem. In response, QuarkChain has designed a series of mechanisms to solve this problem. This can be summed up as a two-layer structure with a calculation power allocation and Proof of Staked Work (PoSW) consensus.
First of all, there is a layer of sharding, which can be considered as some parallel chains. Each sharding chain handles the transactions relatively independently. Such design forms the basis to ensure the performance of the entire system. To avoid security issues caused by the dilution of the hash power, we also have a root chain. The blocks of the root chain do not contain transactions, but are responsible for verifying the transactions of each shard. Relying on the hash power distribution algorithm, the hash power of the root chain will always account for 51% of the net. Each shard, on the other hand, packages their transactions according to their own consensus and transaction models.
Moreover, QuarkChain relies on flexibility that allows each shard to have different consensus and transaction models. Someone who wants to launch a double-spending attack on a shard that is already contained in the root chain must attack the block on the root chain, which requires calling the 51% hash power of the root chain. That is, if there are vertical field projects that open new shards on QuarkChain, even with insufficient hash power, an attacker must first attack the root chain if he or she wants to attack a new shard. The root chain has maintained more than 51% of the network’s hash power, which makes the attack very difficult.

https://preview.redd.it/rxpohs7jb9f51.png?width=674&format=png&auto=webp&s=e2df1307a1753542472f2b6da88e7a4022b30884

As illustrated in the diagram, if the attacker wants to attack the QuarkChain network, one would need to attack the shard and the root chain simultaneously.
PoW has achieved a high level of decentralization and has been verified for its stability for a long time. Combining PoW with the staking capability for PoS would make use of the advantages of both consensus mechanisms. That is what QuarkChain’s PoSW achieves exactly.
PoSW, which is Proof of Staked Work, is exclusively developed by QuarkChain and runs on shards. PoSW allows miners to enjoy the benefits of lower mining difficulty by staking original tokens (currently it’s 20 times lower). Conversely, if someone malicious with a high hash power and does not stake tokens on QuarkChain, he will be punishable by receiving 20 times the difficulty of the hash power, which increases the cost of attack. If the attacker stakes tokens in order to reduce the cost of attack, he/she needs to stake the corresponding amount of tokens, which may cost even more. Thus, the whole network is more secure.
Taking Ethereum Classics (ETC) as an example, if ETC uses the PoSW consensus, if there was another double-spending attack similar to the one in January, the attacker will need at least 110Th/s hash power or 650320 ETC (worth $3.2 million, and 8 TH/s hash power) to create this attack, which is far greater than the cost of the current attack on the network (8Th/s hash power) and revenue (219500 ETC).
Relying on multiple sets of security mechanisms, QuarkChain ensures its own security, while providing security for new shards and small and medium-sized projects. Its high level of flexibility also allows the projects to support different types of ledger models, transaction models, virtual machines, and token economics. Such great degrees of security and flexibility will facilitate the blockchain ecosystem to accelerate growth of innovative blockchain applications.

Bitcoin at $ 288,000? BTC price shows bullish signal like 2016

Bitcoin at $ 288,000? BTC price shows bullish signal like 2016
Bitcoin's price development has been relatively stable in recent weeks.
The cryptocurrency has been trading in the $ 9,200 range since early June, which is the price at the time of publication.
However, Bitcoin is currently showing signals that could indicate an upcoming bull market.
According to a report by the Kraken Stock Exchange, Bitcoin is only a 10% jump away from entering a massive upward trend.
As Kraken describes, to enter a bull market, Bitcoin must break the key resistance at $ 10,500, as shown below.
https://preview.redd.it/0d4bm64zsla51.png?width=1276&format=png&auto=webp&s=b3a670c135792f34af6714fc8ab9d48cef7dc77e
With that in mind, the report says Bitcoin could soon break resistance or take the risk of testing support at $ 6,000 to $ 7,000.
This would end a period that some analysts have described as very stable. In fact, this is similar to the price development in 2016 and 2017, when Bitcoin initially tended to move sideways for a very long time and finally reached its all-time high of USD 20,000 in late 2017.
According to analyst Moon Capital, the Bitcoin hash ribbons have crossed, revealing a massive buy signal that has historically pushed Bitcoin's price up. The signal was also there before the 2017 Bull Run.
Therefore, the analyst predicts that BTC will rise to $ 288,000.
The "hash ribbons" indicator is based on the hash rate of the Bitcoin network.
It is calculated by comparing the short-term moving average and the long-term moving average of the Bitcoin hash rate. As soon as these two cross, a bullish indicator is generated.
A breakdown is considered bearish.
Capriole's digital asset manager, Charles Edwards, also noted the formation of this indicator.
However, Edwards recommended waiting until midnight today (July 12th UTC) for the crossing of the hash ribbons to be confirmed. He also said the BTC price for confirmation should close above $ 9,230.

Bitcoin fundamentals support upcoming uptrend

On the other hand, Bitcoin's fundamentals seem to support a bull market. Bitcoin's hash rate has increased significantly since the difficulty adjustment in June.
According to blockchain.com, the hash rate of Bitcoin reached a new high of 125.99 terra hashes per second (TH / s) on July 7.
In this context, analyst and inventor of Bitcoin's stock-to-flow model, Plan B, said Bitcoin has weathered the worst of the past few months.
In addition, he stressed that the cryptocurrency will soon peak at its hash rate, confirming the good health of the Bitcoin network.

Reinvesting vs. Profit Taking...

Hi all, new to cloud mining and researching at the moment.
I was wondering whether anybody could share their experiences and things to consider regarding 'reinvesting' vs. profit taking.
As I understand, retaining the same hash rate as the difficulty adjustment increases reduces your reward. Reinvesting your reward into greater hash power will merely keep you treading water in terms of your reward rate, and eat into your take home profits. Surely there comes a point where you decide to stop reinvesting and take the profit instead?
Or am I correct in thinking that people reinvest to retain their hash power, with the expectation that the coin will be worth considerably more in the future and the profit can be taken by cancelling the reinvest option further down the line where the profits will be greater?
Is my above logic correct? What other considerations are there? Are there reinvesting strategies that people use?
Thanks in advance.

I made an upgraded calculator for Hashflare, with reinvestments and difficulty increase!

Final EDIT: I have deactivated the links, too many people asking to edit. I recommend to everyone: buy Bitcoin, ETH or altcoins and hold them. As for me, I'm all in on RaiBlocks -> /RaiBlocks
EDIT 1: Changed to consider an optional BTC price increase
EDIT 2: Changed to consider mining fees, thanks for the suggestions
EDIT 3: Optimize number of days using Goal Seek
EDIT 4: Fixed bug in BTC price increase ( thanks madmax_br5 ) - you will now see bigger profits in the chart as it is using the projected increased value.
EDIT 5: Added comparison with buying BTC now and selling later. 3-4x more in my case.
EDIT 6: Overhaul after WandringAnteater 's suggestions. He also gave a more in depth explanation of the inputs and outputs here
EDIT 7: Changed to reinvest from the payout and not balance; fallback to balance if payout < 0.01 TH/s equivalent. Thanks to u/erikkubica for reporting the bug.
I saw many calculators around the sub (thanks for those by the way!), but they didn't consider the increases in difficulty, making for huge profits in the end. This one considers a constant increase in difficulty, compounded (specify the amount and period of increase).
Reinvestment is also considered, you can specify the percentage and how long you wish to reinvest.
There are still many things that are unpredictable, but this at least can give us a more conservative view on potential profits (no longer 10x, but about 3x in my case - at current BTC price).
Maybe someone smarter than me can take this calculator and create automatic optimization on the reinvestment percentage and time. As of now you have to insert your values and wait about 5 seconds to re-calc.
Any criticism is appreciated!

My Recent Experience With Genesis Mining // Read This Before You Buy A Contract

I put $8,200 USD on a total of three Genesis Mining contracts for 50 TH/s of hash power last November, and which only went into effect a mere six months ago in February/March of this year. Now, they're in danger of becoming terminated in less than 60 days because of the low BTC price + increased hash rate difficulty. I had done a bit of research beforehand and tested out some hash rate mining scenarios that may occur at some point in the near future; even multiplying the then hash rate several times over, while keeping the BTC price relatively average (back then it was around the $8K mark and rising).
In all my benchmarks, the amount of hash power I had purchased appeared to make a profit, albeit a small one in even an increasing hash rate difficulty scenario—but never did I imagine that the contract would become unprofitable in such a short period of time. I thought I'd be able to ride it out for at least 1–2 years and either make my ROI or hold for longer to make a possible margin of profit. Plus, my payouts (when they were being generated) never reflected the numbers I had come up with using mining calculators during my research phase; instead, I was only generating half of what was depicted, which was another unexpected curve ball.
Genesis Mining had the audacity of sending out an email about two weeks ago where they stated the following:
In a couple of days, we will roll out a very special offer only for our existing Bitcoin Mining customers. You better stay tuned!
So that very special offer arrived earlier today via another email, and if was for existing customers to upgrade to the new Radiant contracts for $180 per 1 TH/s, which if you do the math would come out to $9000 for the 50 TH/s (or more than I had paid for the original contracts to begin with). They also callously stated in that same email:
As a result, some user contracts are now mining less than the daily maintenance fee requires to be covered, and thus they entered the 60 days grace period, after which open-ended contracts will get terminated.
Although I agreed to Genesis' terms prior to signing up, I never imagined this scenario unfolding in such a short time; however, for them to also add insult to injury with a deplorable marketing scheme as the one I illustrated in the email above should hopefully give you an idea of who you'll be doing business with, in case you're considering a cloud mining contract with them. My advice to anyone interested in cloud mining would be to either pay for your own equipment and mine the BTC yourself, or better yet, buy the BTC directly from an exchange, especially right now while its price is relatively low and hold onto it. I would discourage anyone from pursuing cloud mining as you'll most-likely have no legal recourse since you'll be dealing with a foreign entity that's not bound by the same laws or ethical requirements as the ones in your country.

Are New Bitmains’ ASIC Devices Profitable?

Are New Bitmains’ ASIC Devices Profitable?
You might have heard that Bitmain has announced the next generation Antminer ASIC mining devices.These devices (S17+ and T17+) are expected to deliver higher hash rates while keeping relatively comparable energy consumption rates.
Bitmain stays true to itself and regularly releases new hardware on its Antminer line. Usually, their products are the top ones on the market in terms of hash rate, but it’s always just a matter of time until the competition catches up.

https://preview.redd.it/131m5wm3wgu31.png?width=1920&format=png&auto=webp&s=f96ef5ad457b46ec058849117432921c2da4821e
Also, there is another problem with third-parties pre-empting the devices and then reselling them at a much higher price. One can only hope that this time Bitmain manages to deliver a reasonable amount of devices.
This time, Bitmain is releasing two devices: S17+ with a hashrate of 72 TH/s that is consuming around 2,920 watts of power and an ‘economy class’ T17+ with 64 TH/s and 3,200 watts of power consumption.

What’s the Profit?

So how profitable it is to run one of these devices considering the current state of market? According to Blockonomi’s calculations, S17+ is profitable to operate, but if you’re hoping for big wins, that’s not going to happen. Assuming an electricity price of $0.10 per kilowatt and running your device for 24/7 for an entire year (no change in difficulty considered) you can expect to earn about half a bitcoin. However at the end of the day, it all comes down to electricity costs.
As for T17+, you could get about 0.45156798 BTC, at the cost of $2,8 in electricity fees.

Is it worth it?

Like everything in the crypto space, this is very hard to predict.
Once these devices hit the market, they will set the hash rate standard, which means increasing network difficulty and lowering the efficiency of the hardware.
Moreover, the bitcoin prices have been bouncing around the $7,500 to $8,000 mark for a while, and if your goal is to sell all of the bitcoin you’ve mined right away, you would probably be able just to cover the equipment and electricity cost after one year but nothing more.
If you are determined that ASIC mining is your thing, it can be a good idea to buy one of these devices but avoid purchasing it from the resellers.

The Bottom Line

No matter which equipment you decide to go with, you can use CoinFly to increase your profits.
We offer you an opportunity to mine the most profitable currency and optimize the mining profit automatically: once the situation on the market changes, the system will just switch to mining the most profitable coin, thus, you will have the possibility to tune your hardware online to achieve optimal performance.

Recent events:
  1. Lodge proposed a plan to use the PoW contributed towards mining 0xBTC to secure an offchain bridge. https://medium.com/@jlogelin/arbitrary-off-chain-security-using-0xbitcoin-merged-proof-of-work-7c4ff0d07d3f
  2. 0xBitcoin was listed on Rootrex, which is a DEX that's partnered with Bithumb. Acydutz lead the initiative by simply explaining the idea behind the project and sending them a few 0xBTC to play around with. https://medium.com/@oneroot/oxbitcoin-will-get-listed-on-rootrex-at-14-00-utc-8-on-november-13-77930052fc55
  3. 0xBTC was listed on CoinCalculators.io, a site which tracks the benefits of mining various cryptos. https://www.coincalculators.io/coin.aspx?crypto=0xbitcoin-mining-calculator
  4. The sponsored article was published on CryptoCurrencyNews last week. After the community gathered 9 ETH in donations to pay for the fee, MoonBoy3000 did most of the heavy lifting in regards to the writing, with a lot of help from Mr. F. The result of that was an eloquently written article that is sure to win some more people over to our camp. https://www.ccn.com/0xbitcoin-ethereums-answer-to-bitcoins-proof-of-work/
  5. Frogger pulled some strings and got us a 0xBitcoin banner on https://coinhub.news/.
  6. The SEC has really begun cracking down on ICOs (https://www.coindesk.com/after-fridays-sec-actions-experts-say-ico-party-is-truly-over). The developments effectively mark the end of the era of centrally-generated arcade tokens, clearing the path for a fairer, more transparent method of distribution. Userbrn has written a brief article about IMOs and how they could be used to start blockchain projects in a much more accountable manner. https://medium.com/0xbitcoinfoundation/developers-need-to-consider-initial-mining-offerings-on-ethereum-28be23fa05d9
  7. Userbrn submitted a listing application to Bittrex. Don't be bothering him about the progress on it though, since no decent exchange will speculate about listings. If it goes somewhere, then I'm more than sure that we'll know.
  8. Work on the LavaWallet is currently held up by improvements that have yet to be made to Ethereum, but as soon as those get ironed out the ball will surely get rolling again. In the meantime, Infernal_toast has written this short recap of the LavaWallet: "The LavaWallet contract is a custodial token contract and it is entirely non-owned. Any user is allowed to deposit tokens inside and they will be recorded in the contracts ledger for withdraw by that user at any time. Besides just allowing users to deposit and withdraw tokens, the contract also uses ECRecover so that any tokens inside can be spent by any other pre-specified third party who can submit a signed packet of data (a Lava Packet) which had been signed by the token owner to allow this action.This means that a LavaPacket acts just like a digital check. A user creates and signs this check which specifies an amount of tokens to send to a specific party. A reward (in tokens) can be embedded as well such that anyone who pays the ether gas to submit this check back to the contract will receive. Thus, this allows users to indirectly pay for token transfers using only tokens as the fee. The third parties (relayers) will pay the ether for gas. Once a lava packet is submitted, it cannot be submitted again. One clear fault of such a system is that if anyone can be a relayer and submit a lava packet, then packets which are broadcast to everyone will be submitted by everyone in a race and only the first will be successful. The rest will just lose gas and receive no reward, making for an inefficient system. To solve this minor fault, lava packet creators must specify an address called 'relayAuthority' which is either the address of a specific account , who becomes the only valid relayers for that packet , or a specific arbitrary smart contract whose method getAuthority() is called at time of packet submission which may only return a single address at any given time. Therefore this problem is solved and at any given time, there is only a single valid relayer for any LavaPacket, as enfoced by the contract. This means there will be fewer races, fewer failed tx even with packet broadcasting ,and the power is still in the hands of the user.One such example contract for a relayAuthority has been constructed which uses Proof of Stake and cycles through valid stakers in a ~15 minute interval. LavaPacket creators may use this as a relay authority so that the packet can be submitted by any of the 15 stakers, but still at any given time only one will be a valid submitter so there are still no races, still no reason for invalid TXes."

Hashflare +-zero if 10% difficulty increase every 14 days in average! (we have even higher now!)

Simple calculation. 365 days mining (contract) means 26 difficulty changes (every 14 days). Imagine it's always 10% increase... safe and exactly 10%. That means, that we increase our difficulty from "1873105475221" to "22323905475221". To do it simple: we increase from 1873 to 22323. This is an increase of 1191%. (26 times 10% increase in a row). Taking now every difficulty value after 14 days for the whole 365 days and then taking the average from all of it we get (simplified) 8401.
According to this website, a 17 TH/s contract with ~17% pool fees (hashflare) and a safe block reward of 12.5 all the time, a static btc price of 17.500$ and the price for 17TH/s-contract (OLD PRICES!) it means that you do a +-zero with this contract, if the difficulty would be like 10% all the time. https://www.coinwarz.com/calculators/bitcoin-mining-calculato?h=17000.00&p=0.00&pc=0.00&pf=17.00&d=8401205475221.60000000&r=12.50000000&er=17500.00000000&hc=2695.00
tl;dr: lets hope that difficulty wont increase 1x% every 14 days from now. lets hope btc value wont drop back to 10.000USD or even less.
tl;dr2: If difficulty is higher than hoped for, but BTC increases to 30.000USD you obviously did some money with your hashflare contract. But if you just buy the coin from a marketplace today for 17.500 USD you would have done MORE money with just keeping it in your wallet than cloud mining with hashflare.
tl;dr3: dont trust those youtubers, they just do tons of money with affiliate programs and not with mining.
KEEP THIS IN MIND PLX, it's looking like free money without working for it, but think about your dad's wise words: you will get nothing free in life!
sry for bad english.

Best Investment I ever made

What’s up Reddit!
InnovaMine is a new cryptocurrency cloud-mining site that is licensed and regulated under the trade board of Australia. They are very transparent and have quite good customer support. Primarily though, they have flat out the best pricing for 2-year bitcoin mining contracts due to their push to grow quickly. With Bitcoin pushing along hard right now and the bull market beginning, this is certainly the right time to invest before we see 20k again. Even at current prices of 1 Th/s for roughly $16, you would be earning $10.52 a month and be on track to recover your entire investment in just 47 days. That is unheard of. This is largely because mining has not been profitable for some time and the mining difficulty is low right now. Just another reason why right now is the best time to try this out.

Why is it so hard to mine for bitcoin?

Why is it so hard to mine for bitcoin?
Bitcoin mining has become more competitive than ever.
Bitcoin mining difficulty – the measure of how hard it is to earn mining rewards in the world’s largest cryptocurrency by market cap – has reached a new record high above 7.93 trillion. That’s a seven percent jump from the 7.45 trillion record set during the recent two-week adjustment cycle, which was the highest since October 2018.
Bitcoin is designed to adjust its mining difficulty every 2,016 blocks (approximately 14 days), based on the amount of computing power deployed to the network. This is done to ensure the block production interval at the next period will remain constant at around every 10 minutes. When there are fewer machines racing to solve math problems to earn the next payout of newly created bitcoin, difficulty falls; when there are more computers in the game, it rises.

https://preview.redd.it/s7grcdbkzdn31.png?width=728&format=png&auto=webp&s=4fc30767e70d67539747186fdd5a7d01511c4cbd
Data from Bitcoin Block Explorer - BTCNEWZ.com
Right now the machines are humming furiously. Bitcoin miners across the world have been performing calculations at an average 56.77 quintillion hashes per second (EH/s) over the last 14 days to compete for mining rewards on the world’s first blockchain, according to data from mining pool.
Data further indicates the average bitcoin mining hash rate in the last 24-hour and three-day periods were 59.58 EH/s and 59.70 EH/s, respectively, even higher than the average 56.77 EH/s from May 15 to June 27, or any 14-day data in the network’s history.
Similarly, data from blockchain also shows the aggregate of bitcoin computing power was around 66 EH/s as of June 22, surpassing last year’s record high of 61.86 EH/s tracked by the site, and has more than doubled since December 2018 when the hash rate dropped to as low as 31 EH/s amid bitcoin’s price fall.
Assuming all such additional computing power has come from more widely used equipment such as the AntMiner S9, which performs calculations at an average rate of 14 tera hashes per second (TH/s), that suggests more than 2 million units of mining equipment may have been switched on over the past several months. (1 EH/s equals to 1 million TH/s)

https://preview.redd.it/b681p3plzdn31.png?width=1440&format=png&auto=webp&s=49efa21d8460553aceb87b64a106170b30a4c76a
The increase in capacity is also in line with bitcoin’s price jump over the first half of 2019, which caused the price of second-hand mining equipment to double in China, and also juiced demand for new machines.
Further estimates the bitcoin mining difficulty will jump by another seven percent at the beginning of the next adjustment cycle, which would be the first time for bitcoin mining difficulty to cross the eight trillion threshold.
Delayed plugging in
Such computing interest comes at a time when mining farms in China, especially in the country’s mountainous southwest, have been gradually plugging in equipment as the rainy summer approaches.
According to a report published by blockchain research firm Coinshare, as of earlier this month, 50 percent of the global bitcoin computing power was located in China’s Sichuan province.
However, it’s important to note that this year, the arrival of the rainy season in China’s southwest has been delayed by nearly a month compared to previous years. As a result, some local mining farms were only running less than half of their total capacity in the past month.
Xun Zheng, CEO of mining farm operator Hashage based in Chengdu that owns several facilities across China’s southwestern provinces, said there had been no rain in the area for over 20 days since early May, which was “unusual.”
“In the past years, it usually starts raining continuously throughout May so [hydropower plants] normally will have enough water resources by early June,” he said.
As a result, in early June his firm was only operating at 40 percent of capacity; it can host more than 200,000 ASIC miners. But as the rain has arrived gradually over the past two weeks, the proportion has climbed to over 60 percent.
Mining farms in China previously estimated that the total hash rate this year during the peak of the rainy season around August could break the threshold of 70EH/s. That means another 300,000 units of mining machines could be further activated, assuming all are AntMiner S9s or similar models.
Those waiting to be switched on will also include new capital in the sector such as Shanghai-based Fundamental Labs, a blockchain fund that has invested $44 million on top-of-the-line mining equipment, which will be activated in June.

Am I missing something about bitcoin.com's cloud mining contracts ?

according to https://pool.bitcoin.com/ :
1 TH/s costs $250 for 5 years
their calculator shows an expected daily profit (after fees, at current difficulty and price) of 0.00019337 BCH ($0.11) per day
so $0.11*365*5 = $200 revenue for a $250 contract from the get-go, and that is expecting the difficulty to stay the same, and we all know it will probably increase and make the contract less profitable.
Am I missing something ? Did anyone ever made a profit from these contracts ?

[Hopefully] Extensive Genesis Mining Math - Looking at network difficulty: -38.6% terminal ROI (yes that's a negative)

I recently got into an argument with someone spewing referral links and touting Genesis (and BitConnect, smh) so I decided to run the numbers the best I could for his situation.
tl;dr You will have a return of investment of -38.6% (yes, negative) before your contract is cancelled because of increased network difficulty.
Methodology
The Numbers
I started w/ 16.5 TH/s because that is how much the other person said he had. At today's rates, it costs $2,175 to buy 16.5TH/s. Maintenance rate is $0.00028/GHs, so maintenance fee is $4.62 fee per day or $0.1925/hr. I inputted this CoinWarz calculator w/ the $2,175 as the hardware costs, I used power and power costs of 192.5 Watts and $0.001/Wh, which equals the same $0.1925/hr maintenance fee
Initial (read: the one Genesis wants you to look at but is actually misleading) verdict: 228 days to break even. NOTE: this is really important because some people seem to forget this. An investment in Genesis cannot be withdrawn. It's money gone. So after 228 days you haven't doubled your money or even earned $2,175, you have $0. You spent $2,175 and then you got it back. $0 total.
Now, stepping it up, I introduce the effect of network difficulty. From my methodology, we assume that the difficulty doubles every six months. That means that you're making (after maintenance fee) the full $9.54/day on day one, but at month six it's $2.46. Wait a minute, that's not half!! I made this mistake too! Of the initial $9.54, you're earning $14.16 but paying a maintenance fee of $4.62 - so after network difficulty doubles you earn $7.08/day but still have to pay the same $4.62 maintenance fee (your Gemini contract includes nothing about them ever having to provide a better maintenance fee ever).
The network difficulty continues to increase and around the 9 month mark (to be precise, once network difficulty increases 3.065 times or day 280 of your contract) you're earning $4.62/day and your maintenance fee is $4.62 and imminently your contract is cancelled. You've hit the end of the road.
Based on the virtues of linearity, if you're earning $9.54/day on day 1 and $0/day on day $280. Thus you're earning an average $4.77/day over 280 days for a total of $1,335.60, which is a net loss of $839.40 or a return of -38.6% on your initial $2,175.
Conclusion
You will not make money with Genesis. You will lose money, a lot. The only way to make money is through referral links. That makes Genesis an MLM scheme.
EDIT: formatting.

Bitcoin Mining Power Hits New High as Half a Million New ASICs Go Online

Bitcoin Mining Power Hits New High as Half a Million New ASICs Go Online


News by Coindesk: Wolfie Zhao
The computing power dedicated to mining bitcoin has hit yet another new high, suggesting that more than 600,000 powerful new machines may have come online in the last three months.
According to data from crypto mining pool BTC.com, bitcoin’s two-week average hash rate has crossed another major threshold, reaching 85 exahashes per second (EH/s) around 19:00 UTC last Friday. Meanwhile, mining difficulty also adjusted to a new record of nearly 12 trillion.
Notably, both figures have jumped 60 percent since June 14, the data shows.
Bitcoin’s mining difficulty — a measure of how hard it is to create a block of transactions — adjusts after 2,016 blocks, or roughly every two weeks. This is to ensure the time to produce a block remains around 10 minutes, even as the amount of hashing power, deployed by machines around the globe competing to win freshly minted bitcoins, fluctuates.
Several new models of application-specific integrated circuit (ASIC) miners hit the market over the summer, with an average hashing power around 55 tera hashes per second (TH/s).
Assuming all of the 35 EH/s of new hashing power added since mid-June came from these top-of-the-line models, a back-of-the-envelope calculation suggests that more than half a million such machines have connected to the bitcoin network. (1 EH/s =1 million TH/s)

Billion-dollar business?

These powerful ASIC miners, made by major manufacturers such as Bitmain, Canaan, InnoSilicon and MicroBT, are priced from $1,500 to $2,500 each. So if more than half a million of them were delivered, as estimated above, the leading miner makers could have made $1 billion in revenue over the past three months.
Bitcoin’s spiking hash rate and difficulty are in line with the soaring price since earlier this year, which led to increasing demand for mining equipment that has significantly outstripped supply. It’s also in part thanks to the rainy summer season in southwestern China which resulted in cheap, abundant hydroelectric power.
Further, there has also been a growing interest in Russia’s Eastern Siberia region, where the Brastsk hydropower station built in the Cold War era has been utilized to power mining farms that are estimated to account for almost 10 percent of the total computing power on the bitcoin network.
Miners in China estimated earlier this year that bitcoin’s average hash rate in the summer would break the level of 70 EH/s, which happened in August.
As such, major miner manufacturers have already sold out equipment that is due for shipment until the end of the year with customers placing pre-orders three months in advance.
TokenInsight, a startup that focuses on analysis of crypto trading and mining activities, said in a report published Friday that additional supplies of miners are expected to hit the market in the coming months.
“Following the drastic increase in bitcoin’s price, the bitcoin mining market saw significant inflation in Q2 2019. Most of the miners from various manufacturers were in serious shortage and pre-orders submitted in Q2 and Q3 are to be delivered by the end of the year,” the report states.
Therefore, the firm estimates mining difficulty will maintain its growth momentum to reach 15 trillion by the end of the year — with bitcoin’s average total hashing power crossing the threshold of 100 EH/s for the first time in its history.

I've been working on a bot for crypto subs like /r/bitcoin for a few days now. Say hello to crypto_bot!

Hey guys, I've been working on crypto_bot for some time now. It provides a bunch of features that I hope will enhance your experience on /bitcoin (and any other subreddit). You can call it by mentioning it in a comment. I started working on this a few days ago. I'm constantly adding new features and will update this post when I do, but if you're interested I'll post all updates and some tips at /crypto_bot. Please either comment here, message me, or post there if you'd like to report a bug, request a feature, or offer feedback. There's also one hidden command :)
You can call multiple commands in one comment. Here's a description of the commands you can use:

Market Data:

crypto_bot 
Responds with the USD price of one bitcoin from an average of six of the top bitcoin exchanges (BTC-E, Bitstamp, Bitfinex, Coinbase, Kraken, Cryptsy).
crypto_bot ticker 
Responds with the USD price of one bitcoin at seven exchanges (all of the ones listed above, plus LocalBitcoins). Also lists the average at the bottom.
crypto_bot [exchange] 
Responds with the USD price of one bitcoin from [exchange] (any of the seven listed above).
crypto_bot [litecoin|ltc|dogecoin|doge] 
Responds with the USD price of one litecoin, or the price of 1 doge and 1,000 doge.

crypto_bot [address] 
Responds with information about [address], including its balance and number of transactions.
crypto_bot [transaction_id] 
Responds with information about [transaction_id], including what block it was included in, its size, and its inputs and outputs.

Calculators:

crypto_bot calc <# miningspeed> [#][w] [#][kwh] [#][difficulty] [hc$#] [$#] [#%] 
Responds with calculations and information about how a miner would do with the above data (mining calculator). The only required field is mining speed. Order of the arguments does not matter. Everything other than hashrate defaults to the following if not given: w (watts): 0, kwh ($kilowatt cost/hour): 0, difficulty: current network difficulty, hc$ (hardware cost): $0, $: current bitcoin price in usd (according to Coinbase), % (pool fee): 0. The calculator does not account for nor allow for input of the increase/decrease of difficulty over time, though I may add this feature soon. Working hashing speeds: h/s, kh/s, mh/s, gh/s, th/s, ph/s.
Example usage: "crypto_bot calc 30th/s 10w .12kwh hc$55 1.5%" (to make it easier to remember, th/s can also be inputted as ths). This calls the bot with a hashrate of 30 th/s, electricity usage of 10w, a cost of $.12 kWh, a hardware cost of $55, and a pool fee of 1.5%.
crypto_bot number of btc <$amount to convert> [bp$bitcoin price] 
Responds with the number of bitcoins you could buy with <$amount to convert>. If the comment specifies a [bp$bitcoin price], it calculates it with that exchange rate. Otherwise, it uses the rate from Coinbase.
Example usage: "crypto_bot $419.29 bp$180.32" This calculates how many bitcoins you can buy if you have $419.29 and the bitcoin exchange rate is $180.32.

Broadcasting

SignMessage! "" 
Signs a message in the bitcoin block chain in a transaction using OP_RETURN. The message must be less than 40 characters.
Example usage: "SignMessage! "Post messages in the block chain!""
I hope you find this bot useful! Again, if you have any questions or comments, please either comment on this post, message me, or post on /crypto_bot.
Update 1 (June 24, 2015, 17:35): The bot now responds with information if you post a link to a block, transaction, or address on Blockchain.info in a comment, even if you don't call it. For example, if I wrote "https://blockchain.info/block/0000000000000000126448be07fb1f82af19fbbf07dd7e07ebcd08d42c2660cb" in a comment, it would respond with information about block #362,377.
Update 2 (July 10, 2015, 1:59): The bot now has two additional commands: "unconfirmed transactions" (or "unconfirmed tx") and "explain transaction delay" (or "explain tx delay"). The first command responds with the number of unconfirmed transactions, and the second explains why transactions might take extra time to confirm.
Update 3 (August 24, 2015, 1:34): The bot now responds in a better way than before when transaction ids or addresses are posted. Before, it only responded when the transaction id or address was used in a link to Blockchain.info. Now the bot will respond whenever a transaction id or address is posted at all; a link to Blockchain.info is no longer necessary.
Update 4 (August 27, 2015, 3:00): The bot can now sign messages in the Bitcoin block chain using OP_RETURN.

How much would I have to spend to profitably mine bitcoin?

Currently (Nov. 28th 2017.) annual net earnings just with one Antminer s9 in Serbia is 8.986 USD.
As an investor or small/middle size miner you should consider: the price of bitcoin, investment for mining equipment and the price of electricity.
Superb mining equipment are ASIC processors specially made for bitcoin and alternative (all other) coins mining.
Currently (Nov. 2017.) for mining the bitcoin the best ASIK processor in the world is Antminer s9. It cost from $1.500 up to $3.500. The price varies depending on the series (each subsequent series has better performance), where it is bought (it's a big difference if you buy it directly from the manufacturer or via eBay or Amazon), shipping costs (can be from $0-200) and power supply unit cost from $105 to $200.
The cheapest electricity in Europe is in Serbia. 0,065 € (≈0,077 USD)
Source: Eurostat._YB16.png) (Eurostat is a statistical office of the European Union located in Luxembourg).
One of the essential heritage of communism that has remained in Serbia is that the price of electricity is a social category. So, in Serbia, unlike the rest of the world (perhaps in the communist countries), it is a cheaper electrical cost for domestic households than for the industry.
I decided to pinpoint exactly how much it would electricity cost if 2 Antminers s9 were mining 24/7 365 days a year. The calculation is based on Serbian Dinars. The final value is in US Dollars.
In Serbia, there are 3 zones of electricity categories depending how much of power do you consume per 30 days accounting period: green (0-350 KWh) blue (351 KWh-1.600 KWh) and red zone (more than 1.600KWh). Each zone has own price range. Each zone has night ( lower) and day ( higher) price. Night prices are calculated from 11pm-6am for each zone. Meaning, 16 hours (66,66%) during a day processor will consume higher priced el.energy and 8 hours ( 33,33%) lower priced el.energy.
One Antminer s9 processor consumes 1.400W = 1,4 KW x 24h = 33,6KW / h consumed in one day.
So two processors consume 67,2 KW / h / day
Green zone is up to 350 KWh. So, 350 KWh: 67,2 KWh / per day = 5,2083 days
5,2083 days x 24h = 124,9992 h.
33,33% of 124,9992 h = 41,6622h (lower price hours) x 1,419din. (lower price of el. in the green zone) = 59,1187 din.
66,66% of 124,9992 h = 83,3244 h (higher price hours) x 5,962din. (higher price of el. in green zone) = 496,7804 din.
The blue zone is from 350 KW to 1.600KW
1.600 KW-350 KW = 1.250 KW (the amount of electricity that can be spent in the blue zone price range)
1250KW: 67,2 KWh / per day = 18,6011 days
18,6011 days x 24h = 446,4264 h.
33,33% of 446,4264 h = 148,7939 h (lower price hours) x 2,236din. (lower price of el.price in blue zone) = 332,7032 din.
66,66% of 446,4264 h = 297,5878 h (higher price hours) x 8,943din.(higher price of el.price in blue zone) = 2.661,3280 din.
Red Zone
It remains 6,2 days in the red zone
The number of days spent in the green zone is 5,2
+
The number of days spent in the blue zone is 18,6
23,8 days spent
Calculation period 30 days -23,8 = 6,2 days in the red zone
6,2 x 24h = 148,8h
33,33% of 148,8h = 49,5950h (lower price hours) x 4,472din. (lower price of el. coast in the red zone) = 221,7890 din.
66,66% of 148,8h = 98,208h (higher priced hours) x 17,887din. (higher price of el.cost in the red zone) = 1.756,6464 din.

The profitability of mining bitcoin ( and other altcoins) is calculated with the power consumption calculator. Simply, chose the coin ( in this case bitcoin) enter the hash power of processor ( in this case 14 TH) and el. coast ( in this case 0,039 USD). When you put all this data, you are making just with 1 Antminer s9 $8,986 in Serbia. Power consumption calculator. Source: cryptocompare.com
Now we can do a little investment brainstorming.
Let's say you rent 10 apartments and in each, you will put two S9s. Rent in Serbia (not in Belgrade) for a flat on less attractive location, is $ 110 (can be even less), x 10 apartments that will cost you $1.100 a month.
The Internet per month is $12 x 10 flats = $120
Electricity per month is $79,45 x 10 flats = $794,5
Since this is a serious investment and business, you need 3 people (8 hours shift) for monitoring the processors pay the bills preventing possible stilling, just to make sure everything goes smoothly. The salary per person is $300, so monthly is $900. For these three persons, you can rent an apartment from where they will monitor the processors, which is an additional $ 200 per month (maybe even less).
Monthly expenses are 3.114,5 $
2 Antminers s9 are making (with current bitcoin mining difficulty, block size and price rate) $1.477,3 x 10 flats = $14.773 per month
Month Net Profit: $11.658,5 x 12 months = $139.902 Annual Net Profit
The variable cost is purchasing price of Antminer s9. From $ 1.500 to $ 3.500 (customs, delivery charges, where do you bay). We need 20 Antminers x $3.500 = $70.000
In a year (at the current bitcoin price) the gross profit is $139.902 - $70.000 ( purchasing price for 20 Antminer s9) = Net profit: $ 69.902 in the first year.
The costs could be further reduced:
~~ If you pay in advance ( 6 months or 1 year ) rant
~~ The price of an Antminer s9 is cheaper in a larger quantity order,
~~ I am not sure but, I spouse you can have better price from internet provider for large internet packet
Why two Antminers s9? Under the law, EPS ( Serbian state electrical company) is required to provide up to 30.000KWh annually to each household. The two Antminers S9 spend 24.192KWh yearly.
…..and there is more to talk about this subject.
So, if you have someone in Serbia I wish you all the best. Call me for dinner ( at least you owe me that :)) .
Or, if you are interested in this and you don’t have contacts in Serbia, you can contact me about this project. [email protected]
Stay happy,
Lazar

What did I calculate wrong?

Alright, so I'm thinking about getting into mining Litecoin. I've never mined before, and sadly, my computer, even though it's great for gaming, just won't cut it because of ASIC computers. So I was looking at this one and it said the hash rate was 13.5 TH/s so I went to this website to see how much that would equate to in USD. It says I'd make more than $2 million every month, which I know is very very far off. But what did I do wrong to calculate it?

PSA: Hashflare isn't as profitable as it seems like it is

For example, if you purchase 1 TH/S of hash rate, in one year, you'll only profit ~$10. This is because of the maintenance fee of $0.0035 per 10 GH/S, and also the increasing difficulty of mining.
Calculation: http://www.mycryptobuddy.com/BitcoinMiningCalculatopath?hashrate=1&powerCost=0&poolFee=0&rejectRate=0&hardwareCost=220&sellingProfile=never&recurringCosts=10.85
The recurring cost of $10.85 per month is because of the maintenance fee. $0.0035 * 100 = $0.35 per day. $0.35 * 31 Days = 10.85 per month

How to get $100 million in VC funding to build an industry that makes $300 million profit without spending a dime

Yesterday I received an unexpected gift: a link to a copy of the slides of the presentation that 21inc gave to investors, apparently between October and December 2014, when they were still calling themselves "21E6".
(The sender asked to remain anonymous, and I am not sure about the copyright status of the file; so I would rather not repost it here yet. But it seems that several other people, including some of the 21inc competitors, have got a copy too; so anyone who is really interested can probably get it too.)
The slides don't have much new factual information, and basically confirm what we already guessed about the 21inc business plans. But they show that we severely underestimated their chutzpah and hype. Here are some random highlights (as far as I can decipher from the slides):
They had three relevant mining rig designs in the plans, that would require funding:
Codename Qty TH/s kW Cost Deploy Turnoff Profit($) --------------- ---- ---- --- ---- ------------ ----------- ----------- CyrusOne(v2), 7904 2.0 1.3 --- (already on) Apr 2015 ~23,000,000 IO(v1v3) 3250 5.2 1.3 2000 Jan 2015 Aug 2016 ~24,000,000 Brownfield(v3) 1900 5.5 1.3 2450 Mar 2015 > Nov 2017 ~20,000,000 
The "TH/s", "Cost", and "kW" columns are per "system", i.e. a mining unit containing many chips. The last column is the expected profit to be made from each set of mining hardware over its expected lifetime. (The slides have some other details that do not seem to be important.)
The first line is the hardware that they were mining with at the time of the presentation; that must be why the "Cost" (as far as investors are concerned) is given as zero.
The second line seems to be an upgrade of their previous mining hardware from v1 chips (which gave 2.7 PH/s total at the time) to v3 chips (which would give 17 PH/s) .
In reality, we have seen that their share of hashpower dwindled through all of 2015, and (AFAIK) they haven't mined a single block in the last six months. Were they still mining with CyrusOne on extra-life, or were they using the upgraded IO which was turned off prematurely? What happened to Brownfield?
However, their mining operations were secondary; the meat of their plan was the embedded chip, called BitSplit at the time.
The BitSPlit chip (as we suspected) was hard-wired to send 75% of the block reward to the 21inc wallet, whose address was burned in the silicon, and 25% to the user's wallet.
By my calculations, assuming 50 GH/s and no increase in the difficulty, the BitSplit would mine one block in 570 years, on average, and collect less than 2 BTC of reward in that time. So, of course, the chip was hard-wired to mine into a pool run by 21inc, that would spread the user's 25% of those 2 BTC (expected) into a daily regular trickle of a couple thousand satoshis. Their own mining operations would provide the BTC needed for the pool payouts of all the millions of chips that they expected to be running out there.
They projected to release 3 versions:
Model Qty GH/s W Cost Deploy Profit($) --------------- ---------- ---- -- ---- ------------ ------------ USB hub-charger 250,000 38 15 $35 Mar 2015 ~8,000,000 Embedded chip 1,000,000 63 15 $8 Aug 2015 ~103,000,000 BitSplit Inside 10,000,000 20 5 $0 Oct 2015 ~292,000,000 
The "Qty" is the expected number of units sold. The last column, IIUC, is the profit that 21inc expected to make from the 75% cut of the BTC produced by all the chips, over their expected lifetime.
In the above "USB hub-charger" model was a USB charging unit, roughly 3 x 2 x 1 inches, with 2 USB outputs and a mining chip inside, produced by 21inc themselves "to seed the market".
The second line, which I called "Embedded chip", seems to refer to discrete BitSplit chips provided by 21inc and included in consumer devices (like routers etc.) by OEM manufacturers.
The "BitSplit Inside" model would be the BitSplit integrated into the chipsets of other manufacturers, and manufactured by them. Its cost is listed as "$0" (for 21inc) because they expected those manufacturers to shoulder the cost of manufacturing and integrating the mining chip.
Apparently the market-seeding "USB hub-charger" was later replaced by the "Bitcoin Computer" (aka the PiTato). In one slide it is called "multifunctional BitSplit device", and depicted as a sleek shiny black box, the size of a cigarette pack, with a power cable and 2-3 USB or similar outputs. If that is supposed to be the PiTato, presumably they had not yet realized that a 15 w computer would need a cooling fan with a miniature wind tunnel on top.
In the last two entries, the manufacturers (not the device owners!) would be rewarded with the 25% slice of the BTC mined by those embedded chips. As an example, the slides say that a manufacturer who produced one quarter of the embedded BitSplits would get the 25% cut on the BTC yield of those chips, that was estimated to be between 2 and 4 million dollars per year of revenue in 2015--2018. Those numbers are based on the following predicted mean BTC prices: $350 for 2015, $1000 for 2016, $2200 for 2017, and $5500 for 2018.
So, their main business plan was fantastic: the OEM and chipset makers would pay the costs of producing and integrating the chips, the consumers would pay the cost of operating them, and 21inc would get 75% of all BTC mined by them, expected to be worth 400 million dollars.
It makes sense to invest 100 million in that plan, right?
EDIT1: Sentence order, typos.
EDIT2: See also this comment below about other sources of this info and this comment about a fatal flaw of the PiTato mining chip.
EDIT3: See also this comment with the data from slide 2, "At a glance"

question about mining profits

Hi, I would really like to have your opinions on my mining project. I want to buy 30 S9 which have about 13.5 TH/s (1350W) and cost around 2500$ each. The electricity where I live is around 0.07$/KWh. If I plug all these infos into:
http://mycryptobuddy.com/BitcoinMiningCalculator
I'm profitable in less than 10 weeks which means that if I put all my earnings into S9s I can get 30 new ones.
So every 10 weeks I can double the number of S9 I have.
If I do that for 50 weeks I get 960 S9 . (30 x 25=960)
It seems too good to be true..even if I don't take into account the mining difficulty and the BTC price change. (I don't think it matters that much, I'm using the same ratio between the two for the full year)
Am I missing something here?
(edit:I'm assuming I have enough funds to preorder the S9 and get them exactly in 10 weeks intervals)

Concerns about re-investing strategies

Hello folks, I bought a 2.8TH contract on December 31st, my initial thought was to proceed with a typical reinvestment strategy of 190 days and then reap the profits from that point on. So far I've been sticking to my plan and reinvested every day, even though BTC value has been like a rollercoaster this month. According to one of these xls calculator plans, reinvesting every day for 190 days at a presumed difficulty rate of 8% (just 1% more than the average increase of 2017), would get me, with 190 days of reinvesting (bringing my total hash power to 14.12THs) and 175 days of withdrawing, around 0.06611 BTC, so around 945$ with the BTC value of today, and that's great, breaking even plus 300$ or so, and a couple hundred more in the 190 days of dwindling hash rate when all the one year contracts I got for reinvesting expire. If BTC continues it's year-by-year upward trend and has a modest 12% price increase, I'll be looking at around 1,100$ at day 365, and a couple hundred more as contracts expire. Awesome. If it skyrockets and breaks that $20k resistance, that's beyond my wildest dreams.
But... what happens if difficulty increases more than the 8% everyone assumes it will? It just increased 15% today, and two 17-18% increases in December. If this continues and there's an average of 15% increase every two weeks for most of the rest of the year, then at day 365 I'm looking at.. 0.001939 BTC, and with a very generous 20k bitcoin, a measly 40$, and not even enough BTC to withdraw from Hashflare... On the other hand, with this pessimistic projection and no compounding, yes, I'm stuck with 3.15 THs for a year, but at least I'll be accumulating a significant amount of bitcoin in the initial period where BTC difficulty is still manageable. It's still gonna bring me to around a 100$ loss, but at least 100$ loss is better than a 600$ loss, right?
What do you guys, obviously much more experienced in this than myself, say? Any faults in my logic here? Any words of comfort?
