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.

What prevents state actors from proxying millions (USD) to mining pools to launch a 51% attack.

Update

u/cointastical made some awesome arguments about a POW fork being pre-baked and ready as a "break glass" emergency roll-out. This HAS been done before BTW. Another great idea about having a grass-roots campaign for everyone to use the invalidateblock command on their node to nullify the attack. Again done before, though on another coin.
Assuming that there exists some subset of miners that work completely to their own self interests and without any greater good or altruistic motives, how would you foresee the following dystopian fiction play out.
By rough estimates about 80% (proof tbd) of the bitcoin network mining exists in mining pools. These pools compete in a free market to entice independent miners to join their pool. The rates are paid in BTC per TH/s. The current price to "rent" the entire bitcoin networks pooled mining resources is about $9 to $10 million / day (proof). This is entirely within the budget of state actors, even the $3 billion to rent the bitcoin network for an entire year doesn't sound far fetched when considering government spending.
So if a state actor (government) were to partner with some established mining pool they could subsidize that pool to offer unrealistically high rates to entice more and more miners (in their self interest) to join their pool.
Once they reach majority (51%) they could exclude blocks from other small independent mining pools tilting the tables more in their favor. These early attacks would create long (25 block) reorgs (proof), but eventually, as they gained more market, they could make the attacks pretty quick. Each attack could exclude blocks from a 1% pool, 2% pool, and so-forth till they attack 1/3 (33%) of the miners at which point they control the whole network (proof tbd).
So assuming miners work in their own self interest, why wouldn't they join this obviously evil mining pool if that pool was offering 50% above market rate for their mining power compared to competitors?

Why The Actual Cost Of Mining Bitcoin Can Leave It Vulnerable To A Deep Correction

In early 2020, researchers predicted the cost to mine Bitcoin will be at around $12,000 to $15,000 after the block reward halving in May. But, it is now much cheaper to mine BTC than the initial estimates. The low breakeven price to mine Bitcoin may leave it vulnerable to a correction.
Bitcoin has become more affordable to mine in recent weeks due to two main factors: difficulty adjustments and cheaper electricity in Sichuan, China due to the rainy season.
A low breakeven price of Bitcoin can raise the probability of a price pullback because miners have more incentive to sell BTC, which may increase selling pressure in the short-term.
On May 11, the third block reward halving in the history of Bitcoin occurred. A halving is activated every four years and it decreases the amount of BTC miners can generate by half.
A halving is necessary for Bitcoin because the dominant cryptocurrency has a fixed supply of 21 million BTC. As it reaches towards its maximum supply, the rate of producing BTC decreases to provide balance.
But, when a halving happens, miners experience a near-50% cut in their revenues overnight. As such, it typically leads over-leveraged miners to capitulate or stop operating due to high costs.
When fewer miners are mining BTC, the Bitcoin network automatically adjusts the difficulty to mine BTC.
Since Bitcoin miners use computing power to mine, big mining centers can usually mine more BTC after the difficulty adjusts.
The Bitcoin blockchain network saw two difficulty adjustments in the past three months, allowing major miners to see higher revenues in the short-term.
Here’s where the extra surplus of BTC becomes a problem.
According to several Chinese miners based in Sichuan, China, electricity in the region costs around $0.04 per kilowatt-hour.
Due to the rainy season and the abundance of hydropower plants in the area, mining industry executives state that large mining centers in China can often negotiate lower electricity prices.
With $0.04/kwh, miners based in China said that the breakeven cost to mine Bitcoin hovers in the $5,000 to $6,000 range.
Even individual miners running commercial mining equipment like the Antminer S9 is operating at a breakeven cost of $8,206.
“To be completely accurate: Given current difficulty, 0.04$/kWh and S9 running custom firmware bringing it down to 71W per TH efficiency. The cost to mine 1 BTC is 8206.64$. Meaning its still profitable,” one miner said.
Considering the cost to mine Bitcoin for both big mining centers and individual miners can range in between $5,000 and $8,500, miners have more incentive to sell to cover operational costs rather than to hold onto the BTC they mine.
According to data from ByteTree, Bitcoin miners did not sell much Bitcoin in the past week. Around 6,825 BTC were mined and 6,298 BTC were sold, leaving 527 BTC in net inventory.
In previous weeks, especially throughout March, on-chain data shows that miners sold more Bitcoin than their revenues.
Yet, the price of Bitcoin struggled to see a short-term rally despite the noticeable decline in selling pressure from miners since the start of June.
The relatively cheap cost to mine Bitcoin and the failure of BTC to break out of a multi-year resistance level at $10,500 with fewer sellers in the market raise the likelihood of another correction.

Antminer T19 May Not Affect Bitcoin Hash Rate but Keeps Bitmain Ahead

The Antminer T19 by Bitmain may not have a big impact on the Bitcoin network, and it comes out amid the firm’s internal and post-halving uncertainty.
Earlier this week, Chinese mining-hardware juggernaut Bitmain unveiled its new product, an application-specific integrated circuit called Antminer T19. The Bitcoin (BTC) mining unit is the latest to join the new generation of ASICs — state-of-the-art devices designed to mitigate increased mining difficulty by maximizing the terahashes-per-second output.
The Antminer T19 announcement comes amid the post-halving uncertainty and follows the company’s recent problems with its S17 units. So, can this new machine help Bitmain to reinforce its somewhat hobbled position in the mining sector?
T19: The cheaper S19
According to the official announcement, the Antminer T19 features a mining speed of 84 TH/s and a power efficiency of 37.5 joules per TH. The chips used in the new device are the same as those equipped in the Antminer S19 and S19 Pro, though it uses the new APW12 version of the power supply system that allows the device to start up faster.
Bitmain usually markets its Antminer T devices as the most cost-effective ones, while the S-series models are presented as the top of the line in terms of productivity for their respective generation, Johnson Xu — the head of research and analytics at Tokensight — explained to Cointelegraph. According to data from F2Pool, one of the largest Bitcoin mining pools, Antminer T19s can generate $3.97 of profit each day, while Antminer S19s and Antminer S19 Pros can earn $4.86 and $6.24, respectively, based on an average electricity cost of $0.05 per kilowatt-hour.
Antminer T19s, which consume 3,150 watts, are being sold for $1,749 per unit. Antminer S19 machines, on the other hand, cost $1,785 and consume 3,250 watts. Antminer S19 Pro devices, the most efficient of three, are considerably more expensive and go for $2,407. The reason Bitmain is producing another model for the 19 series is due to what is known as "binning" chips, Marc Fresa — the founder of mining firmware company Asic.to — explained to Cointelegraph:
“When chips are designed they are meant to achieve specific performance levels. Chips that fail to hit their target numbers, such as not achieving the power standards or their thermal output, are often ‘Binned.’ Instead of throwing these chips in the garbage bin, these chips are resold into another unit with a lower performance level. In the case of Bitmain S19 chips that don’t make the cutoff are then sold in the T19 for cheaper since they do not perform as well as the counterpart.” The rollout of a new model “has nothing to do with the fact that machines are not selling well,” Fresa went on to argue, citing the post-halving uncertainty: “The biggest reason machines probably are not selling as well as manufacturers would like is because we are on a bit of a tipping point; The halving just happened, the price can go anyway and the difficulty is continuing to drop.” Product diversification is a common strategy for mining hardware producers, given that customers tend to aim for different specifications, Kristy-Leigh Minehan, a consultant and the former chief technology officer of Genesis Mining, told Cointelegraph:
“ASICs don’t really allow for one model as consumers expect a certain performance level from a machine, and unfortunately silicon is not a perfect process — many times you’ll get a batch that performs better or worse than projected due to the nature of the materials. Thus, you end up with 5–10 different model numbers.” It is not yet clear how efficient the 19-series devices are because they have not shipped at scale, as Leo Zhang, the founder of Anicca Research, summed up in a conversation with Cointelegraph. The first batch of S19 units reportedly shipped out around May 12, while the T19 shipments will start between June 21 and June 30. It is also worth noting that, at this time, Bitmain only sells up to two T19 miners per user “to prevent hoarding.”
Hardware problems and competitors
The latest generation of Bitmain ASICs follows the release of the S17 units, which have received mostly mixed-to-negative reviews in the community. In early May, Arseniy Grusha, the co-founder of crypto consulting and mining firm Wattum, created a Telegram group for consumers unsatisfied with the S17 units they purchased from Bitmain. As Grusha explained to Cointelegraph at the time, out of the 420 Antminer S17+ devices his company bought, roughly 30%, or around 130 machines, turned out to be bad units.
Similarly, Samson Mow, the chief strategy officer of blockchain infrastructure firm Blockstream, tweeted earlier in April that Bitmain customers have a 20%–30% failure rate with Antminer S17 and T17 units. “The Antminer 17 series is generally considered not great,” added Zhang. He additionally noted that Chinese hardware company and competitor Micro BT has been stepping on Bitmain’s toes lately with the release of its highly productive M30 series, which prompted Bitmain to step up its efforts:
“Whatsminer gained significant market share in the past two years. According to their COO, in 2019 MicroBT sold ~35% of the network hashrate. Needless to say Bitmain is under a lot of pressure both from competitors and internal politics. They have been working on the 19 series for a while. The specs and price look very attractive.” Minehan confirmed that MicroBT has been gaining traction on the market, but refrained from saying that Bitmain is losing market share as a result: “I think MicroBT is offering option and bringing in new participants, and giving farms a choice. Most farms will have both Bitmain and MicroBT side by side, rather than exclusively host one manufacturer.”
“I would say that MicroBT has taken up the existing market share that Canaan has left,” she added, referring to another China-based mining player that recently reported a net loss of $5.6 million in the first quarter of 2020 and cut the price of its mining hardware by up to 50%.
Indeed, some large-scale operations seem to be diversifying their equipment with MicroBT units. Earlier this week, United States mining firm Marathon Patent Group announced that it had installed 700 Whatsminer M30S+ ASICs produced by MicroBT. However, it is also reportedly waiting for a delivery of 1,160 Antminer S19 Pro units produced by Bitmain, meaning that it also remains loyal to the current market leader.
Will the hash rate be affected?
Bitcoin’s hash rate plummeted 30% soon after the halving occurred as much of the older generation equipment became unprofitable due to the increased mining difficulty. That spurred miners to reshuffle, upgrading their current rigs and selling older machines to places where electricity is cheaper — meaning that some of them had to temporarily unplug.
The situation has stabilized since, with the hash rate fluctuating around 100 TH/s for the past few days. Some experts attribute that to the start of the wet season in Sichuan, a southwest Chinese province where miners take advantage of low hydroelectricity prices between May and October.
The arrival of the new generation of ASICs is expected to drive the hash rate even higher, at least once upgraded units become widely available. So, will the newly revealed T19 model make any impact on the state of the network?
Experts agree that it won’t affect the hash rate to a major degree, as it’s a lower output model compared with the S19 series and MicroBT’s M30 series. Minehan said she doesn’t expect the T19 model “to have a huge impact that’s an immediate cause of concern,” as “most likely this is a run of <3500 units of a particular bin quality.” Similarly, Mark D’Aria, the CEO of crypto consulting firm Bitpro, told Cointelegraph:
“There isn’t a strong reason to expect the new model to significantly affect the hashrate. It might be a slightly more compelling option to a miner with extraordinarily inexpensive electricity, but otherwise they likely would have just purchased an S19 instead.” Bitmain continues to hold leadership despite internal struggle
At the end of the day, manufacturers are always in an arms race, and mining machines are simply commodity products, Zhang argued in a conversation with Cointelegraph:
“Besides price, performance, and failure rate, there are not many factors that can help a manufacturer differentiate from the others. The relentless competition led to where we are today.” According to Zhang, as the iteration rate naturally slows down in the future, there will be more facilities using “creative thermal design such as immersion cooling,” hoping to maximize the mining efficiency beyond just using most powerful machines.
As for now, Bitmain remains the leader of the mining race, despite having to deal with the largely defunct 17 series and an intensifying power struggle between its two co-founders, Jihan Wu and Micree Zhan, which recently resulted in reports of a street brawl.
“Due to its recent internal issues, Bitmain is facing challenges to keep its strong position in the future thus they started to look at other things to expand its industry influences,” Xu told Cointelegraph. He added that Bitmain “will still dominate the industry position in the near future due to its network effect,” although its current problems might allow competitors such as MicroBT to catch up.
Earlier this week, the power struggle inside Bitmain intensified even further as Micree Zhan, an ousted executive of the mining titan, reportedly led a group of private guards to overtake the company’s office in Beijing.
Meanwhile, Bitmain continues to expand its operations. Last week, the mining company revealed it was extending its “Ant Training Academy” certification program to North America, with the first courses set to launch in the fall. As such, Bitmain seems to be doubling down on the U.S.-based mining sector, which has been growing recently. The Beijing-based company already operates what it classifies as “the world’s largest” mining facility in Rockdale, Texas, which has a planned capacity of 50 megawatts that can later be expanded to 300 megawatts.

Actual cost of a 51% attach, $10.2 million

So I was discussing this last week and honestly it all felt too simple, so I'm trying to get some stronger counterpoints to this argument. Goes something like this.
You have some pool miner that wants to do a 51% attack. Lets assume the attack has three phases, the first phase is to try to accumulate 51% of the hashing power, next is the accumulation of more hashing power by ejecting other pools from through reorg. Finally when they aquired enough mining power they could blacklist exchange hotwallets or all manner of nefariousness. Lets further assume that everyone will act purely in their own self interest. For simplicity lets call the attacker "Spectre Pool".

Accumulation Phase

Assuming Spectre Pool can hit something like 41% of the hashing power, the first goal is to accumulate more resources to hit 51%. Since pool mining is a commodity market, all Spectre has to do in this imaginary world is offer more than the market rate. Since they are already at 41% hashrate, they need to entice another 10% of the market to come to their pool. The obvious way to do this would be to offer a "new customer bonus" or something like that. Some promotion where they pay 1% above market price for the hashing power of pool members. So, given a network hashrate of 116.73 EH and a market rate of 0.101 USD/TH per day, the cost they would have to bear to offer a 1% promotion to entice 10% of the network would be:
116.73_EH / 0.101_USD/TH * 10% * 1% = 1,155,742 USD per day for each 1% "bonus"
So, assuming they were willing to spend that much on "marketing", and that all miners worked in their own self interest, eventually they could lure enough miners over to achive 51%. Once they hit this threshold they could scale back on the "marketing" and thus reduce their daily burn.

Acceleration phase

Once at 51%, the next attack of Spectre will be to put their smallest competitor out of buisness. Lets call that the "Bond Pool", and pretend that Bond has 1.5% of the network hashing power. To put Bond out of buisness, with 51%, Spectere will need to reorg whenever Bond wins a block. By reorging to a chain without Bond, this will put Spectre one block behind and they will need to catch up. Once the reorg begins, Spectre will need to produce the longest chain on its own while starting one block behind. So we need to determine how long (statisticly) it will take Specter to produce n+1 blocks and compare that to how long (statisticly) it will take Bond to win one block.
Although this can be hammered out in an iterive calculation, a better approach will be an algebraic solution. Lets walk through the equations:
You can put the following into a GeoGebra CAS calculator to substitute and simplify the equations
solve(n*m = s*(n+1), n) M = 1/2-d S = 1/2+d m = t/M s = t/S solve(n*m = s*(n+1), d) n = s/(m-s) b = m*M/p solve(b = s*(n+1),p)
This will produce the following equations for the values we are interested in.
m(t,d): t/(1/2-d) # from `m` define s(t,d): t/(1/2-d) # from `s` define n(s,m): s/(m-s) # from `n` solve d(n): 1/(4*n+2) # from `d` solve p(d): 2*d # from `p` solve b(t,p): t/p # from `b` define
Plugging the equations into excel produces the following (assuming t=10)
n d p m s b
25 0.98% 1.96% 20.40 19.62 510
20 1.22% 2.44% 20.50 19.52 410
15 1.61% 3.23% 20.67 19.38 310
10 2.38% 4.76% 21 19.09 210
5 4.55% 9.09% 22 18.33 110
4 5.56% 11.11% 22.50 18 90
3 7.14% 14.29% 23.33 17.50 70
2 10% 20% 25 16.67 50
1 16.67% 33.33% 30 15 30
So once d=0.98%, Specture will have 50.98% of the hashing power, allowing him to eject 1.96% of all blocks mined at will. Of course this is all statistical, so Spectre will want some margin for randomness. So it would make sense to attach 1.5% of the blocks when Spectre reaches 51%
So once Spectre reaches 51% he has enough hashing power to prevent any of Bonds blocks (1.5%) from being included. Spectre can win a reorg (statistically) every 8.5 hrs and Bond can only produce a block (statisticly) every 11.1 hours. So once this attack starts, Spectre simply flashes his promotion to lure the miners in the Bond pool (who are receiving no reward) over to the Spectre pool. If he only gets one third of them, then he can increase his influence to 52%
Doing the same math again, with 52% Spectre can ice out any pool who has up to 4% of the hashing. Then running the promotion, Spectre will try to get 40% of the "homeless miners". Now Spectre's power grows to 55% giving him the power to ice out 10% of his competitors. This can cascade on and on until Spectre is the only public pool left.
Now, at 51% the attack and reorgs take many hours, but as more and more pools get targeted, more and more miners will jump ship and end up at Spectre so long as they can hold the promotion. Bond's only choice would be to either close up, or leverage everything and mine at a loss for weeks hoping that Spectre eventually drops below the threshold for his attack.
Of course Spectre has even more tremendous expenses. To offer the 1% promo to 10% of the network would cost Spectre $1.16 million / day, or 3.52 million per month for each percent of miners it lures over. So going from 41% to 61% would cost Spectre $70.3 million / month, but at that point he can attack 20% of the network giving him a reach of about 80% which is pretty much the entire pooled mining capacity today. Seems like $70 million is a small price to pay to buy the entire bitcoin network.
Other expenses Spectre would accrue would be related to the attacks and reorgs. The early attacks will take hours and throughout Spectre needs to continue payouts to the pool even though he is generating no BTC durring the attack. So long as his chain is orphaned, his blocks have no value. Only after the attack and reorg when his chain becomes longest will he be able to claim the block reward for all the blocks he minded. This (in my opinion) will the the hardest challenge. The first attack and 25 block reorg will require Spectre to put his entire 51% hashing power on an orphaned chain for 8 hours requireing $208.6 million in payouts. Once he wins the attack and the chain reorgs he can cover his expeses with the block reward, but borrowing $208 million for 8 hours is still a very difficult thing to pull off. The interest alone on the attack is over $40,000 (20% interest compounded continually). Below is a table of the calculations
Specte Bond Promo Cost Hrs Blks Levrg / Block Reorg Leverage Rate Int Cost
51.00% 1.50% $1,155,743 8.497 25 $8,025,990 $208,675,743 20% $40,485
51.50% 2.50% $1,232,745 5.825 17 $8,025,990 $144,467,822 20% $19,215
52.50% 4.50% $1,336,143 3.492 10 $8,025,990 $88,285,891 20% $7,039
54.50% 7.50% $1,562,998 2.141 6 $8,025,990 $56,181,931 20% $2,746
58.50% 14.50% $2,023,385 1.140 3 $8,025,990 $32,103,960 20% $835
66.70% 33.30% $2,970,442 0.500 1 $8,025,990 $16,051,980 20% $183
Of course, once Spectre gets 2/3 of the hashing power he controls the entire chain since he can include or exclude any block he wants. So this "Total Self Interest" simulation of a 6 day attack puts Spectre's expenses at $10.3 million in promotions and $71,000 in interest, or about $10.4 million total.
1 - All "hashes" are hashes per second
2 - TH = 1012 or 10004 hashes per second
3 - EH = 1018 or 10006 hashes per second

This will produce the following equations for the values we are interested in.

solve(nm = s(n+1), d) n = s/(m-s) b = m*M/p
``` Tb = The avg time between blocks won by Bond durring the reorg Ts = The avg time for Spectre to produce a block durring the reorg Tm = The avg time for the main chain to produce a block durring the reorg n = The number of blocks Specter will need to reorg
Tb = 10_min / 49% / 3% = 10.89 Hrs Ts = 10_min / 51% = 19.61 Min Tm = 10_min / 49% = 20.41 Min
Solve for the amount of blocks Specter can reorg Tmn > Ts(n+1) Tnn > Tsn + Ts n > Ts/(Tn - Ts) n > 24.5
Therefore: Spectre can produce 26 blocks faster than the main chain can produce 25. Specter has to win the reorg before Bond produces another block
Assert: Ts * (n+1) < Tb 19.61_min * 26 < 10.89_hrs 8.50_hrs < 10.89_hrs ```
So once Spectre reaches 51% he has enough hashing power to prevent any of Bonds blocks from being included. Spectre can win a reorg (statistically) every 8.5 hrs and Bond can only produce a block (statisticly) every 10.89 hours. So once this attack starts, Spectre simply flashes his promotion to lure the miners in the Bond pool (who are receiving no reward) over to the Spectre pool.

Doing the same math again, with 52% Spectre can ice out any pool who has up to 7% of the hashing. Then running the promotion, Spectre will try to get 40% of the "homeless miners". Now Spectre's power grows to 55% giving him the power to ice out 16% of his competitors. This can cascade on and on until Spectre is the only public pool left.

[Researh] In 2017 bitcoin network consumed 5 TWh of energy, in 2018 – 29 TWh, in 2019 – 43 TWh. Banking industry consumes 74 TWh per year.

[Researh] In 2017 bitcoin network consumed 5 TWh of energy, in 2018 – 29 TWh, in 2019 – 43 TWh. Banking industry consumes 74 TWh per year.
Electricity consumed by bitcoin network has been constantly and noticeably increasing. During the past years the consumption reached such big a scale, that it can be compared to electricity consumption of some countries, according to BlockchainAnalytics.pro research.
The world’s first cryptocurrency is steadily becoming more popular and expensive every year. This motivates more individuals and companies to enter the mining business to earn a bitcoin share.

More miners, more efficient equipment

To validate a block of transactions and receive a reward, miners compete with each other by solving a deliberately complicated mathematical task, or puzzle. Those miners who own more computing power (hashrate) have more chances to win the competition. This incentivizes miners to buy more powerful equipment that consumes more electricity.
At the same time, mining equipment efficiency is constantly improving, and with time less electricity is required to produce the same hashrate. This factor allows to slow down the increasing demand for electricity.
For example, in 2016 Bitmain, world’s largest manufacturer of mining equipment, launched the legendary Antminer S9, which consumed 100 watts to produce one terahash per second, or 100 W/TH/s. The best modification of Antminer S15, released in 2018, consumed 57 W/TH/s. Currently, the most efficient Antminer S17 consumes only 40 W/TH/s.

It is assumed that the market competition compels manufacturers to keep up with each other in developing more efficient hardware. If some manufacturer brings next-generation chips to market, other manufacturers start to produce chips with the same characteristics at about the same time.
On the other hand, new miners are joining the network, thus increasing the hashrate. So the demand for electricity continues to grow. Also, it can be noticed later that the electricity consumption chart is similar to that of hashrate chart.
https://preview.redd.it/3k32ci6q09j41.png?width=930&format=png&auto=webp&s=e70f600419bcbc9e7e82506b5f12bf4da6f00584

Calculations

The incremental volume of electricity consumption is calculated by multiplying newly added hashrate by the best mining efficiency available at that moment.
The sum of incremental volumes represents cumulative amount of electricity consumed by bitcoin network. The metric is expressed in terawatt-hours (TWh). To get annualized volume in terawatt-hours we multiply the consumption by 24 hours and 365 days.
A 100-day moving average was applied to hashrate to make the final result less dependent on the short-term hashrate fluctuations.
Assumptions, used in this study, are very conservative. It means that the results are in the lower limit of the range of possible volumes, and the actual electricity consumption can be higher.
A detailed explanation and interactive charts are provided here: https://www.blockchainanalytics.pro/btc/electricity-consumption/

Results

Currently, annualized electricity consumption in bitcoin network is 57 TWh. To help readers get an idea of how much electricity the bitcoin network consumes, a comparison with some countries is provided alongside.
Portugal consumes 49 TWh per year, Romania – 50 TWh, Czech Republic – 59 TWh.
Some more numbers for comparison:

According to conservative estimates, the bitcoin network will consume more than 70 TWh in 2020. This is on a par with Chile, a country with 18 million population.

More thoughts (estimations of how much energy banking industry consumes)

Some information from official reports:
Taking into account the information above, we can assume that, on average, banks spend ~20 kWh per customer per year.
Some information on world population:
  • 69% of adults around the world have a banking account (source)
  • 70% of the world population are adults (source)
  • World population is 7.7 billion (source)
Finally: 7.7 billion people * 70% * 69% * 20 kWh per year = ~74 TWh per year
So, we can assume, that banking industry consumes ~74 TWh per year

Bitcoin Hashrate Records New All-Time High Amid Halving And BTC Bullish Momentum

Bitcoin Hashrate Records New All-Time High Amid Halving And BTC Bullish Momentum

With The Third Bitcoin Halving Already Here, Bitcoin Bulls Are Showing No Signs Of Support For The World’s Leading Cryptocurrency
While the crypto world was frantic about Bitcoin’s third halving event, which occurred on May 12, it came with a bullish sentiment among traders and holders. However, the halving produced 5%-8% price swings in both directions prior to the halving. The market didn’t seem to respond to the much-anticipated halving. The weekend saw $1,3 billion in liquidations, which put pressure on Bitcoin bulls. Shortly after Bitcoin’s reward cut, Bitcoin’s price peaked, before correcting itself to currently trading at $8,745.98
Meanwhile, the Bitcoin mining industry seems to be going all-in on validating blocks, as the computing power on Bitcoin’s network, or hashrate, increased to a new all-time high. The 140 terra hash-per-second (TH/s) all-time high surpassed the recent 135 TH/s all-time high of March 2020, meaning that miners deployed all their recourses to celebrate the halving event.
Source: Coinwarz
The crypto community welcomed the halving, as TIE published data, showing the word “halving” being present in over 2,900 tweets. Reddit also showed signs of buzzing in the moments prior to the halving and shortly after it. Joshua Frank, TIE’s founder commented on the data, stating that “Bitcoin became a hot topic in the past 30 days, with a 72-percent conversation surge, and with peaks in search terms of Bitcoin and halving crypto related terms in Twitter. Bitcoin also surpassed 50,000 daily tweets, which is a new six-month high.”

Source: Twitter
“In the 30-day window prior to the halving, the word “halving” appears to be dominant in the conversations, regarding Bitcoin,” Frank added.
Google searches for “bitcoin halving also increased four times, as opposed to the 2016 halving event.
However, most crypto enthusiasts believed Bitcoin would record double, or even triple-digit price increase, due to the halving. The short rally proved them wrong, but many consider the real price surge to start in the following 18 to 24 months. Historically, Bitcoin showed an initial decrease in value before skyrocketing in both price and trading volumes.
The halving event drove an increase in daily trading volumes in the month before the reward cut. However, trading volumes have increased 50 times since the last halving in 2016. Spot market volumes received a boost from a peak of $1,5 billion in June 2016, and it was close to $30 billion in April 2020.
Nevertheless, market players are still stagnant about making strong predictions about Bitcoin’s future price, as this time it would take longer for the market to gain from the bullish momentum the halving created.

Hello all,
I am here with my plan for my [subreddit]1 Reddit Nation
If you are interested in joining a (hopefully) newly formed island nation then this is the place to be.
I have prepared a plan that explains how we will go about doing such a task. More detailed elaborations for each component of the plan will be given at request.
Obviously the first question is where we would have our island. I have identified places of interest. One place of interest is the Nation of Belize. Belize is a small nation with a low GDP of 2 Billion and they are selling off most of their island. Islands with 50-100 acres can be acquired for around 500,000; give or take 50,000. From the people (Government Officials) I have contacted, they are perfectly okay with this plan.
Now here is a 5 step proposal of how this will come to fruition (I will expand on how we will finance this)
  1. Acquire the island
  2. Set up the initial infrastructure
    1. Form of Government that I propose is a constitutional monarchy
      1. Country will be run as a democracy (two chamber form of parliament)
      2. Noble titles such as Duke, Earl, Count, Lord, Baron etc will be sold off to help initially finance the island.
    2. Establishment of the Government Building
      1. For now this is where the government will convene until more infrastructure is added and the island is improved.
      2. People will be made citizens at this location
    3. Establishment of Civil Services
      1. Waste collection, Police, Social Services
    4. Establishment of a Port
      1. This will allow supplies to enter the island.
      2. This will allow for the island to participate with the rest of the world economically(I will expand on this later).
      3. The port will function as the entrance point and exit until the runway can be constructed.
    5. Establishment of Resident Housing
      1. This temporary housing will be until the island can be developed and more permanent buildings can be put up.
      2. Resident Housing and the Government building will be set up near the port until island development is completed
    6. Set up a massive solar powered crypto mining operation to help finance further development of the island
      1. A partnership with big mining companies can be brokered to have this set up
  3. Make the Island a desirable location
    1. Set up the island as a luxury city
      1. Free housing for citizens
      2. Free healthcare for citizens
      3. Free schooling and university for citizens
    2. Build resorts and legalize gambling on the island
      1. The revenue generated from such activities will help finance further development of the island
      2. With the revenue generated from this, the island will be able to provide for the residents a luxury city
      3. The gambling industry investments will help to finance the island as well
    3. Make the island a banking haven
      1. Set up a bank on the island
      2. No KYC laws will be enforced on the island
      3. This will attract forgien investment into the island
    4. Allow cryptocurrency companies to conduct business without oversight and for miners to set up large scale operations using solar powered energy
    5. No income tax,sales tax, capital gains tax or corporate on the island
      1. Commercial businesses such as casinos, resorts, and banks will just pay slightly inflated property taxes
      2. This will help attract a lot more forgien investment as well
      3. Will attract companies to set up offices here and thus bring jobs to the island.
  4. Expand on the island infrastructure
    1. Build an airport. The islands have enough space to accommodate runways for planes even up to jumbo jets
    2. Build more free luxury housing for residents
    3. Establish schools and universities
    4. Establish libraries
    5. Establish Museums
    6. Establish a healthcare system
  5. Enjoy the luxury haven of an Island that we have built
Now for the question of how much this island will cost and how we will get the funding
According to my calculations (you can look at them below) it will cost us $2,600,000
Now in regards to how we will raise that sum
If you have made it this far, please join the [subreddit]1 for this plan
More information to come soon, thank you.

Zigmabit fastest and most efficient crypto miners 🔴 SCAM 🔴

Zigmabit fastest and most efficient crypto miners 🔴 SCAM 🔴
https://preview.redd.it/wk4gh9rm3cb41.jpg?width=1280&format=pjpg&auto=webp&s=db173c6ddb6d51581b6e1f638c0a0465df8f5020
We are not even in a bull market yet. Usually these things happen when there is a lot of hype. ZigmaBit is scammer company with fake mining rigs to basically scam you. Their selling website is https://zigmabit.com/ , please don't even click the link. We do not want to give them any traffic, just watch the video down below.
They have listed 3 miners on their website:
  • ZigBit 2.0
  • ZigBit 3.0
  • ZigBit 5.0

https://preview.redd.it/406xtn2l3cb41.jpg?width=1676&format=pjpg&auto=webp&s=4933fa05a303be6ece49fa37c4e8845fa8636605
Which of course doesn't exist. They recommend that these miners will make some crazy gains, which of course will not happen. As these miners are fake. Seeing the specification makes me think these guys know very little about crypto currency mining. So for example the specification they are advertising on ZigBit 5.0 is :
  • Bitcoin-2000 TH/s
  • Litecoin-300 GH/s
  • Ethereum-75 GH/s
  • Dash-50 TH/s
  • Power Consumption-2400W
  • Power Socket 110V-240V
Now you understand what im talking about, seriously 2000 TH/s mining Bitcoin at 2400w (where the latest Antminer S17 is 72Th/s), or mining ETH and the profit is so big that it will cover the miner cost faster then month. And another thing, they using the same hardware to mine multiple currencies which every one of them needs different hardware. Worst thing is that people will loose money, and most likely some of them already did. People think they will get rich after buying this miner, which they will never receive. Their fake products look so bad, their cheapest version ZiBit 2.0 looks like an ATX power supply.

Few things to also note is :
  • They have support chat on their website. I did send them a message and got response after about 20 minutes. So they told me that they only accept crypto currency, and the products are shipped from United Kingdom. My last line of the chat was "im coming for you you'll be in jail soon ".
  • When you google miner name, there is few websites coming up describing how great is their product. This most likely is owned websites for this scammer or this is purchased content posts.
  • Last thing is that i tired to do checkout on one miner, there is btc address which has already received 7btc. Im not sure if this is some people got already scammed or this is fake volume, hope this is fake volume https://www.blockchain.com/btc/address/1C4RSshoK9veR4jCNStqF32QARS5oGnmzw . Hope none is scammed.
Sad to see that there is such kind of people who makes money on scamming others. Man karma is there , i believe it will come for you sooner or later.

Bitcoin hashrate hits a new ATH again

The aggregate computing power of the Bitcoin network exceeded the historical maximum, reaching 68,631,992 TH/s.
https://www.blockchain.com/charts/hash-rate?timespan=2years
Another interesting fact is the number of active addresses per day. The first time BTC exceeded 1 million active addresses in 24 hours was November 2017 when 1 BTC was worth $9352 and the average fee was $3.23.
It happened again on Friday: over 1 million addresses were active and the fees paid by users were on average $1.33. These numbers hadn’t been seen for a long time.
Among the technical reasons that are favouring the growth of the value of Bitcoin, there is also the approaching of the so-called “Halving” (the process of reducing the reward for finding a new block; more detailed here: https://medium.com/letknownews/what-is-halving-and-how-does-it-affect-the-bitcoin-rate-c48a994c833a). The first halving took place in 2012: the reward for a block had decreased from 50 BTC to 25 BTC. The second, on the other hand, occurred in 2016 and went from 25 to 12.5 BTC per block. In both cases, as a direct effect of the reduction in supply, there was an increase in the value of the cryptocurrency.
The next halving is now imminent. In 11 months’ time, in fact, the reward for miners will be halved from 12.5 BTC per block to 6.25 BTC per block. The inflation rate will fall below 2%. The following halving will, therefore, occur in 2024 and 1 block reward will correspond to 3,125 BTC, the rate of inflation will fall below 1%, perhaps even below 0.5%.

The total computing power now dedicated to securing the bitcoin blockchain has set yet another record.

According to data from mining services operator BTC.com, the average bitcoin mining hash rate over the last two weeks has reached 71.43 quintillion hashes per second (EH/s), up from 64.49EH/s on July 23. The threshold was breached as bitcoin adjusted its mining difficulty at block height 586,672 on Monday 2:52 UTC – that is a 6.94EH/s, or 10.78 percent jump since mid July.
Bitcoin mining difficulty is a measure of how hard it is to compete for mining rewards on bitcoin. Just how difficult the bitcoin software makes it to generate new blocks adjusts every 2,016 blocks – approximately every 14 days – to ensure the block production time remains about 10 minutes at the next cycle.
Assume this additional 6.9EH/s (or 6.9 million tera hashes per second, TH/s) computing power has all come from powerful ASIC miners, such as Bitmain’s AntMiner S17 or MicroBT’s WhatsMiner M20S, both of which boast a mining rate of around 55TH/s and recently hit the market.
That means more than 100,000 top-of-line ASIC miners could have been switched on within the past two weeks. Further, given these products have been sold for at least $2,000 each, this equates to some $200 million in revenue pocketed for major miner makers.
The continued interest in bitcoin mining comes at a time when the cryptocurrency’s price appears to be en route to challenging all-time highs, however distantly, and amid the arrival of the rainy season in China, which leads to cheaper hydropower electricity costs in the country’s southwest provinces – a region that is reported to account for 50 percent of the global mining activity,
Miners in China estimated earlier this year that bitcoin’s hash rate in the summer would break the level of 70EH/s. To be clear, at several single points of time, bitcoin’s hash rate had already crossed that level in June and even reached 80EH/s around Aug. 1.
However, today marks the first time that the two-week average computing power has been able to remain above the 70EH/s threshold. As such, bitcoin’s mining difficulty has also set a new record of nearly 10 trillion.

Market change

Amidst this uptick in mining interest, there have been notable changes in the mining market, where top manufacturers are racing to produce more powerful equipment.
For instance, in Bitmain’s 2018 initial public offering prospectus, the Beijing-based mining giant claimed it had a 70 percent market dominance. Now, it may be facing serious competition from rival players that some believe are capable of shipping more top-of-line products with better profitability.
Michael Zhong, a former mining analyst who now operates mining farms at a startup called Force Mine, told CoinDesk that based on his experience, the production capacity ranking among major Chinese miner makers for their flagship products have changed over the years.
Zhong explained that from 2017 to 2018, Bitmain had topped the list with its AntMiner S9 series miners, followed by Canaan’s Avalon 8 series machines. InnoSilicon, Ebang and former Bitmain design director’s MicroBT were all in the third position at the time.
But from January to June this year, the delivery capacity ranking has reshuffled, with now MicroBT’s WhatsMiner M20 series at the top, followed by Bitmain’s S17 series miners and then InnoSilicon, Canaan, and Ebang, Zhong added.
According to F2pool’s miner profit tracker, Bitmain’s flagship AntMiner S17 Pro ranks third in terms of mining profitability, following BitFury’s Tardis and MicroBT’s WhatsMiner M20S. The cost for WhatsMiner M20S is around $3,000, while that of AntMiner S17 Pro is around $4,000 each, based on the information advertised on the two firms’ websites.
Although orders for these flagship machines have queued up until November and December this year, MicroBT’s founder Zuoxing Yang told CoinDesk previously that the bottleneck of production capacity is the availability of chips from suppliers.
For example, MicroBT uses 10-nm chips for its M20 series, which are relatively more affordable with a higher level of availability compared to more advanced 7-nm chips used by Bitmain for its AntMiner S17 series equipment.
While Bitmain has always been relying on chips supplied by Taiwan Semiconductor Manufacturing Company (TSMC), MicroBT has switched from TSMC to Samsung earlier this year for its flagship products.
Both TSMC and Samsung have estimated in their most recent Q2 earnings calls that the demand for cryptocurrency mining chips will come back in the third and the fourth quarter this year.

The "Squire Mining" penny stock company promoted by Coingeek could be a nChain pump & dump scam. Here's the evidence...

"Squire Mining" is a penny stock company, with no revenues. In most years, it had operating expenses around $10,000 - $150,000.
For many years, "Squire Mining" listed its business as literally mining for physical metals & minerals, like copper, gold, tungsten, etc.
Then in August 2018, "Squire Mining" suddenly changed its listed business to say that it's now involved with mining Bitcoin & blockchain applications with ASIC chips.
Wow, what a change. From using shovels to mine for metals & minerals, to using ASIC chips to mine for Bitcoin.
Two months later (October 2018), Coingeek is promoting "Squire Mining", which claims that they now have an ASIC miner prototype, that is faster & more efficient than most commonly used crypto miners on the market, and they will deliver them to Coingeek in 2019.
"Squire Mining" also announced that Stefan Matthews is both the Chairman of nChain and director of Squire.
As homopit noted in the comments, Squire's ASIC design apparently comes from "Aracore"
And the aracore.io website is shady as hell.
And the "About" page has blatant stock photos for team members..
At this point, the penny stock company "Squire Mining" looks like a nChain shell company, acquired through reverse merger.
And it could easily be a pump & dump scam, designed to capture the media hype around "blockchain, Bitcoin, ASICs".
Which wouldn't be surprising, given that nChain's Chief Scientist Craig Wright ("Fake Satoshi") is a known fraudster.

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.

Bitcoin hashrate hits a new ATH again

The aggregate computing power of the Bitcoin network exceeded the historical maximum, reaching 68,631,992 TH/s.

Another interesting fact is the number of active addresses per day. The first time BTC exceeded 1 million active addresses in 24 hours was November 2017 when 1 BTC was worth $9352 and the average fee was $3.23.
It happened again on Friday: over 1 million addresses were active and the fees paid by users were on average $1.33. These numbers hadn’t been seen for a long time.
Among the technical reasons that are favouring the growth of the value of Bitcoin, there is also the approaching of the so-called “Halving” (the process of reducing the reward for finding a new block; more detailed here: https://medium.com/letknownews/what-is-halving-and-how-does-it-affect-the-bitcoin-rate-c48a994c833a). The first halving took place in 2012: the reward for a block had decreased from 50 BTC to 25 BTC. The second, on the other hand, occurred in 2016 and went from 25 to 12.5 BTC per block. In both cases, as a direct effect of the reduction in supply, there was an increase in the value of the cryptocurrency.
The next halving is now imminent. In 11 months’ time, in fact, the reward for miners will be halved from 12.5 BTC per block to 6.25 BTC per block. The inflation rate will fall below 2%. The following halving will, therefore, occur in 2024 and 1 block reward will correspond to 3,125 BTC, the rate of inflation will fall below 1%, perhaps even below 0.5%.
