Is Antminer S9 hardware coming offline? The disappearance of an unusual pattern in the Bitcoin nonce value distribution may suggest so. Regardless, reports have surfaced that mining farms are upgrading to the latest generation hardware.
3 months later. How the profitability of mining changed after halving
3 months later. How the profitability of mining changed after halving On May 11, the size of the Bitcoin mining reward fell by half. The next time it will be in 2024. What devices will be profitable by that time, and what to hope for owners of obsolete equipment. In May 2020, a halving took place on the bitcoin network. The cryptocurrency mining reward has decreased from 12.5 to 6.25 BTC. This is a long-awaited event, which, according to the hopes of the crypto community, should lead to a strong increase in the value of the coin. For example, Anthony Pompliano, co-founder of investment company Morgan Creek Digital, predicted that the rate would rise to $100,000 by the end of 2021, primarily due to lower mining rewards. So far, the bitcoin price hasn’t responded to the halving as much as expected. In mid-May, at the time of the reduction in the mining reward, the BTC rate was around $9,000. To date, the cryptocurrency has risen in price by 27%. This year’s high was set yesterday, August 18, at $12,400. The hashrate of the cryptocurrency network showed a different dynamics. Its value fell immediately after the halving from 137.5 to 87 EH/s, according to bitinfocharts.com. Since mining bitcoins has become less profitable, some of the miners probably turned off their equipment. They could switch to mining other coins or completely abandon this activity due to its unprofitability. Later, when the BTC rate began to rise, the amount of computing power in the coin’s network also began to increase. So, from late May to mid-August, the cryptocurrency hash rate increased from 87 to 130 EH/s. But over the past three days, the figure has dropped sharply by 20%, caused by floods in China. Torrential rains in Sichuan province caused power outages that interfered with the operation of mining farms. Changes in hashrate and mining rewards have affected its difficulty. On May 11, at the time of the halving, this figure was at around 16.1 T. By the current moment, this value has increased to 16.9 T, in July rising to a maximum of 17.3 T. The decline in the reward for mining cryptocurrency was partially offset by the increase in fees. Until May, a single BTC transfer cost the user an average of 50 cents. By the current moment, commissions have grown more than 10 times, to $5.5. Mining profitability is now at around 0.114 THash/s. It fell sharply immediately after the halving from 0.16 to 0.08 THash/s. To date, the indicator has grown by 40%. This was due to the rise in BTC prices and higher fees. Development Director at BitCluster Dmitry Shuvaev said that the profitability of the device for mining BTC s17–73Th/s is now about 8 thousand rubles per month (at an electricity price of 3.5 rubles per kWh). The payback period is about 15 months. Old devices, such as the Antminer S9, are now unprofitable to use, they do not bring profit. But this situation may change if the bitcoin rate rises to $15,000. “We recommend our customers to buy the new generation S17 or S19 devices. It is these devices that will provide profitability until the next halving. Their break-even point is at $6,000 per bitcoin”, Shuvaev said. In June, specialists from the research division of the BitMEX exchange announced that in the long term, 2–3 ASIC miner manufacturers will remain in the industry. Canaan’s Avalon devices were the first to hit the market in 2014. Three years later, in 2017, Bitmain took 75% of the market. Subscribe to our Telegram channel
Got this weird DM on reddit idk what this guy is up to have any of you ever heard of this https://tradeoptiongains.com Site? u/mikerobin25 Mikerobin2501:52 AM Hello there IDEKMyUsername09:34 AM Howdy Mikerobin2509:47 AM How's it going? IDEKMyUsername12:13 PM Not bad. What's up Mikerobin2512:36 PM I'm doing quite alright, How about you? IDEKMyUsername12:53 PM Not bad Mikerobin2501:39 PM Well, I don't mean to intrude but are you familiar with the term "cryptocurrency", Bitcoin to be precise? IDEKMyUsername03:10 PM Yes Aye Mikerobin2503:25 PM Well, I'm at the moment engaging in an outreach aimed at expanding the clientele of my platform and enlightening the populace on the monetary potential of bitcoin trading and mining. Would you be interested in this? IDEKMyUsername03:26 PM Uh yeah sure I can look into it. What does it include? Mikerobin2503:28 PM Are you familiar with the term "Bitcoin trading"? IDEKMyUsername03:29 PM Yeah somewhat Like selling and buying it? Mikerobin2503:33 PM Well, Bitcoin trading is the process of making profits by buying Bitcoin at a low cost and selling it when the price goes up, This method is referred to as Dollar Cost Averaging(DCA). The Bitcoin trade is volatile, and price move by a significant margin. This activity is done on trading platforms. Are you following? IDEKMyUsername04:07 PM Yep gotcha so far Sorry had to pickup a call Mikerobin2506:51 PM No problem mate. Every platform has an investment procedure and ROI method. Unlike other platforms that engage in day trading (profiting from the volatility of bitcoin which is inefficient), My platform is registered with S9 ant miners that mine the bitcoin you invest to increase exponentially and that’s how you earn profits. Have you heard of the term "Bitcoin mining"? IDEKMyUsername06:52 PM Yes I have Mikerobin2506:57 PM Good. For clarification, Bitcoin mining primarily involves generating and earning off the confirmation of blocks of transaction on the network such as the Blockchain network. This is made possible with the use of special and sophisticated devices called the Bit main devices, Such as the AntMiner S9 and ASIC hardware. These devices are extremely expensive to maintain and require a lot of electricity generation and technical expertise which makes it rarely an option for private individuals who are interested in going into Bitcoin mining. But my platform has been able to provide for this disability. Are you following? IDEKMyUsername06:57 PM I feel ya Yes Mikerobin2507:01 PM Moving on, My platform operates a full S9 Antminer farm. The Antminer s9 has a hash rate of 12.93TH/s which is -+ 7%, Which could generate a ROI of 0.5 BTC within an investment period depending on the investment capital. Note: ROI stands for return of investment while hash rates a measure of how many times the network can attempt to complete this puzzle every second. This means that hash rate is a good indicator of the Bitcoin network's health. Do i still have your attention? IDEKMyUsername07:02 PM Yes Mikerobin2507:05 PM Finally, All investments are made and monitored by the client (you) on the platform's website as you earn profits daily and you can contact me a "Broker" on the platform whenever you need assistance or more information. https://tradeoptiongains.com IDEKMyUsername07:05 PM Hm U have a history of wise investments? I mean don't really know you so not like your a "professional" of any means Mikerobin2507:06 PM Certainly We've been running for a span of 4 years now with optimum services provided IDEKMyUsername07:38 PM oh wow gimmie some more deets? how much money would I expect if i put a quick g bar in? IDEKMyUsername07:53 PM hm? Mikerobin2507:54 PM An investment of $1000 amounts up to the standard ROI stated above which is 50% of 1 bitcoin. Apologies for the late reply, Was attending to a client of mine. IDEKMyUsername07:55 PM so invest of about $1000 would give ruffly 5? nah ur good fam like how I go about that tho u know cause isn't bitcoin like kind of high right now? Mikerobin2507:57 PM Yeah though it would have been more profitable if you had started earlier when it was cheaper but you should be expecting more returns due to the halving coming up. https://www.bitcoinblockhalf.com/ IDEKMyUsername07:58 PM how high you think its going to get? Mikerobin2507:59 PM Its a highly speculative asset but from my experience and following it's previous halving events, Probably 15-18k. IDEKMyUsername08:01 PM oh jeez thats like as big as the big boom right? how you know its gonna do that? and what if it doesn't lol? do I just l;ose it all Mikerobin2508:05 PM Exactly. If it doesn't, It would remain at its breaking point of 9k or peak point of 10k but i highly doubt it doesn't pump(rise) based on past halving events. You can simply get started by creating your personal account on the platform by which you can start by purchasing bitcoin and you can do this by clicking on the "Register" icon to get started. IDEKMyUsername08:05 PM hmmm idk Kinda need some more security u know what I mean? Mikerobin2508:08 PM I understand. Loses are only made when you sell off, You money remains intact whether it rises or falls as long as you don't sell but your ROI is fully attained on your account on the platform. IDEKMyUsername08:09 PM o Mikerobin2508:10 PM Indeed Mikerobin2508:20 PM Any more questions? IDEKMyUsername08:20 PM uhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh no Mikerobin2508:22 PM Okay then, I'm available here if you're interested and need my assistance Enjoy the rest of your day.

Now with the recent halving, does the upcoming Antminer S19Pro make sense?
Hi Bitcoin community. This is my first post here so I want to introduce myself a bit. My name is Alex, I'm 25 years old, I live in Italy and I've been a Cryptocurrency miner since January 2017. Right now in my small mining farm I have online 2 Innosilicon S11, one Antminer A3 (All 3 mining a Blake2b coin that I've invested in), 4 Innosilicon A10 and from late 2017 till mid 2019 I had 5 Antminer S9 (14Th/s batches) running. In these days I was thinking if it is worth buying the upcoming Antminer S19 Pro from Bitmain, since as of today (19 May, 2020) with the current difficulty and price, the profit with that ASIC sits around 2,00USD/day (Assuming the power cost is 0,10USD per Kw). Also to keep in mind these new Antminers haven't been delivered yet, so the difficulty will rise even more. In my opinion, unless the minimum BTC price rises to at least the 20.000-30.000USD range, getting the S19Pro is not a great investment. What do you guy think? I'd like to hear your opinions as well.
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.
You made it! :) First up, SORRY! This has been a late post, I have my reasons don't question them (if you must know I'll be posting in the discord - one time only haha). Secondly, I am sure you can agree with me when I say "Wow!" What an incredible week it has been. Last week I thought it was going to take a couple more weeks for more moving price action when it had only taken a few days which has seen Bitcoin reach and pass the $10,000 region. We have also seen the total Market cap for cryptocurrencies increase from about 280B to over 300B (308B at time of writing) within just a few days. A huge injection of liquidity, about 40B, into the market and just to name a few of the best rises in the top 20 (on Coinmarketcap.com), the price of ETH BTC ADA have given good performances/positive responses (With this I will start adding screenshots at the end of each week for timestamp purposes). This may be a combination from Binance, Mastercard, Paypal, Grayscale investments, VISA AND the DEFI sector. Let me explain... Last week we read about Binance integrating with the company Swipe (SXP) to issue there own debit card expanding the use and reach of cryptocurrency to 31 countries within Europe. Binance's Q2 scheduled token burn of $60.5 Million, this figure correlates with its exchange, margin and futures trading platforms where approximately 20% of profits get burned to increase the price of BNB token (careful as the price has been steady after the burn). This week we find out Mastercard's expansion into the Cryptosphere as they expand and integrate with the Wirex team to issue a Mastercard-backed Bitcoin debit card, thus further extending the reach of cryptocurrency availability internationally. "The cryptocurrency market continues to mature and Mastercard is driving it forward, creating safe and secure experiences for consumers and businesses in today’s digital economy " "...Our work with Wirex and the wider crypto ecosystem is accelerating innovation and empowering consumers with more choice in the way they pay" Mastercard is also reaching out to other emerging cryptocurrency firms to apply to become principal members [Partners] with Mastercard as they have relaxed their digital assets program and look to expand into the Digital Assets and Blockchain environment. Paypals expression of interest in cryptocurrency facilitiation may bear fruits as it is said Paypal has partnered up with stablecoin operator Paxos (who is already in partnership with Revolut in the US) to facilitate trading through a cryptocurrency brokerage which will enable other firms to integrate cryptocurrency trading functionalities with them. In my opinion this looks much more promising than the Libra association they pulled out from last October as regulations. Grayscale Investments clears regulatory hurdle as they have been given the green light for its Bitcoin Cash Trust (BCHG) and Litecoin Trust (LTCN) to be quoted in over-the-counter (OTC) markets by US Financial Industry Regulatory Authority (FINRA). “The Trusts are open-ended trusts sponsored by Grayscale and are intended to enable exposure to the price movement of the Trusts’ underlying assets through a traditional investment vehicle, avoiding the challenges of buying, storing, and safekeeping digital Bitcoin Cash or Litecoin directly.” More green lights for Cryptocurrency in the US as regulators allow banks to provide cryptocurrency custody services (which may go further than just custody services). A little bit strange as it seems unnecessary and undermines one of the key factors and uses of cryptocurrency which is to be in complete control of your own finances... On another outlook this may be bullish as it allows US banks to provide banking services directly to lawful cryptocurrency businesses and show support for Bitcoin. Visa shows support stating they have a roadmap for their further expansion into the Crypto sphere. Already working with Crypto platform Coinbase and Fold they have stated they recognise the role of digital assets in the future of money. To be frank, it appears to be focused on stable coins, cost effectiveness and transaction speeds. However they are expanding their support for crypto assets. AND MOST IMPORTANTLY, DeFI! Our very own growing section in crypto. Just like the 2017 ICO boom we are seeing exorbitant growth and FOMO into the Decentralised Finance sector (WBTC, Stablecoins, Yield farming, DEXs etc). The amount of active addresses on Ethereum has doubled but with the FOMO on their network have sky rocketed their fees! Large use-cases of stable coins such as USDT ($6B in circulation using ERC-20 standard), DAI, TUSD, and PAX. $114M Wrapped Bitcoin (WBTC) on their network acts as a fluid side chain for Bitcoin and DEX trade volume has touched $1.6B this month. With all this action happening on Ethereum I saw the 24HR volume surpass BTC briefly on Worldcoinindex.com In other news, Bitcoin has been set as a new precedent in a US federal court in a case against Larry Dean Harmon, the operator of an underground trading platform Helix. Bitcoin has now legally been ruled as a form of money. “After examination of the relevant statutes, case law, and other sources, the Court concludes that bitcoin is money under the MTA and that Helix, as described in the indictment, was an `unlicensed money transmitting business´ under applicable federal law.” Quick news in China/Asia as floods threaten miners and the most dominant ASIC Bitcoin mining rig manufacturer Bitmain loses 10,000 Antminers worth millions alledgedly goes missing or "illegally transfered" with ongoing leadership dispute between cofounders. Last but not least, Cardano (ADA) upgrade Shelley is ready to launch! Hardfork is initiated as final countdown clock is switched on. At time of writing the point of no return has been reached, stress tests done and confirmation Hardfork is coming 29/07 The Shelley Mainnet upgrade is a step toward fast, capable and decentralised crypto that can serve billions of people. With the Shelley Mainnet is ADA staking rewards and pools! Here is a chance for us Gravychainers to set up a small pool of our own. Small percentage of profits going into the development of the community, and you keep the rest! If you read all of my ramblings thanks heaps! I appreciate it! I have added an extra piece of reading called speculation. Most you can speculate on by just reading the headline some others have more depth to them. Another post next week for a weekly round up!

P.S. Dr Seuss collectables on the blockchain HECK YEAH! and Bitcoin enters NASCAR, remember when Doge did this? it was like when Doge was trending on TikTok. ... Oh yeah did I also mention Steve Wozniak is suing Youtube, Google over rampant Bitcoin scams. Wait, what? Sydney based law firm JPB Liberty is suing Google, Facebook and Twitter for up to $300B. Just another day in the Cryptosphere.
The bitcoin halvings in 2012 and 2016 were at times when mining changed from a fun hobby to the beginning of farms and larger mining operations. We went from CPU-GPU-ASIC in these 2 halving periods. The main theme during most of this time was people mining for fun and at a relatively low cost, all while BTC was mainly under $1k. Things changed when the antminer S7 and later S9 came out and BTC began to really rise in price. Miners were making a lot of real money and thus began the creation of major mining farms for profit. When the element of mining as a business is the forefront of the network, selling BTC to cover costs becomes a big part of most operations. We have all heard the number of 1800 BTC created daily during the 12.5 block reward time, and this has translated to around 18,000,000 usd per day @ a $10k BTC price. The reason this is so significant is miners are the only group of people that have brand new BTC that is constantly open sold on the market. Every other person involved in BTC is buying and selling existing BTC supply. When the miner reward is cut to 6.25, this will help in the long run imo, but may add even more selling pressure by miners in the short term. Miners will instantly be making half the amount and will still have the same business costs. Even with rewards cut in half, 900 BTC and $9 million will be created per day as of right now. This is still a huge amount to be absorbed in the market, and we could see even more selling pressure than we do now where a lot of miners have a buffer in mining profits at the 1800 BTC per day network rate. TDLR: Halving will help in the long run but short term could add even more selling pressure than right now at a higher BTC inflation.
Bitcoin Halving: How Miners are Preparing for Lower Block Rewards
As the latest Bitcoin halving approaches, miners are upgrading equipment, optimizing arrangements, conserving power and more in the race to dominate. How are bitcoin (BTC) miners strategizing for the upcoming halving event, in which block reward subsidies will be cut by 50 percent? On this week’s episode of “Bitcoin Halving 2020: Miner Perspectives,” Kristy-Leigh Minehan and Pavel Moravec give an in-depth explanation of what miners are doing to maximize profits and increase operational efficiency. Since October, Minehan explains, bitcoin mining farms have been getting on “the upgrade train” and purchasing state-of-the-art ASIC machines such as the Antminer S17 and S19. Moravec says bitcoin miners have also been looking at creative ways to cut electricity costs by leveraging surplus energy from certain cities’ power grids. What started primarily as a hobby in 2009 has flourished over the years, gained broader adoption and ultimately evolved into a new, professional industry. “We’ve gotten to a point in bitcoin’s history where the government is paying attention and has started to realize bitcoin isn’t going away,” Minehan said. “Mining is not going away. And it’s in their best interest to start working with miners.” Teaming up with local governments and utility providers is another miner strategy both Minehan and Moravec have seen on the increase in recent years. This is why Minehan believes even the geographic distribution of miners, which was discussed in depth in an earlier podcast episode, may further stretch the industry into North America and Europe. (China remains the dominant locale.) Continue Reading On https://www.coindesk.com/bitcoin-halving-podcast-episode-2
Why is the RandomX algorithm being hyped to the moon?
TL;DR: don't assume the average return from mining RandomX will be higher than the current CryptonightR algorithm. Hold back your excitement for now. I think we all need to bring something to our attention. Over the last month, there have been so many topics and comments here on MoneroMining about the new 'RandomX' algorithm. This algorithm is supposed to be launched a couple of months from now. There are many questions like "is this a good hashrate for my CPU"? "What's your power usage on RandomX"? "How can I tune my CPU for RandomX"? "How would the algorithm perform on this hardware"? I think these are great constructive comments that are at the heart of what miners stand for. We miners love optimizing our rigs and educating ourselves on technological trends. But I've noticed many questions such as "what parts should I buy for a RandomX mining rig"? "Is an AMD Ryzen 9 3900x a good investment"? "What parts will give me the most profit when RandomX launches"? Many of these questions are asked with very little research. I think there's a gold fever brewing behind some of these comments. The kind of motives that have bankrupted many miners in the past bubbles. As we have seen in 2014 and 2018, anybody who enters the crypto industry with an 'I want easy profit' attitude almost always goes bankrupt. They buy coins or hardware at the peak of the bubble. Sometimes they get lucky and sell their coins or rigs right before the crash (only to get burned in a future bubble later). But most of the time, these new users lose most of their investment. As a veteran miner, a lot of alarm bells ring in my head when I read these kinds of RandomX hype posts. I have no reason to think CPU mining will be more profitable on RandomX than on the current CryptonightR.
If the new AMD CPUs are very efficient on RandomX, that just means more people will buy them, driving up the difficulty. Your shiny R9 3900x's profit will start falling because it's no longer as competitive against the other hardware on the network.
If the profits on day 1 of the RandomX launch are indeed high, more people will start adding rigs to the network. If the average miner's profit is above the equilibrium of the market, it will start going down. That equilibrium is largely set by botnets, large scale farms in China/Russia/Niagara Falls/Georgia, and datacenters with spare capacity. So if your R9 3900x earns $10/day on day 1, you can count on that golden streak ending soon.
CPU mining as a market is never stable. Your CPU rig is limited tojust 1 or 2 coins: Monero and Veruscoin. Edit: there are a few more CPU coins than these. AMD GPUs can at least mine 3 or 4 coins well, while nVidia GPUs are the best at 5-10 different algorithms. GPU mining is a safer, less risky investment. GPU mining is like playing blackjack. Building a rig specifically for CPU mining is like tossing a coin. You're locked into one coin by building a CPU rig. Yes, it has resale value to gamers, but it's much harder to resell a MOBO combo than a bunch of GPUs at any price. Trust me, I've sold hundreds of GPUs and dozens of MOBOs before!
I don't know what the market share of CPUs vs. GPUs on CryptonightR is right now. But if most of the current nethash is made up of CPUs, these CPUs will have no choice but to switch to RandomX when it is out. There's no other coin for them to mine, unless they have some work to do outside of mining. So almost all of them will get onto the RandomX network, too, along with your expensive new CPU rig. I think this'll be the biggest factor driving up difficulty. Yes, the older CPUs might not be as efficient as the new Ryzens, but many of them are already paid for in terms of capital (like in a datacenter) or have free power (like in a botnet or apartment with free power).
You might say that Monero will always be profitable enough because it has survived so long, or the developers are better, or they're taking action against ASICs. But that doesn't necessarily guarantee profit. Monero might be a successful coin and overtake ETH, but that has nothing to do with profit on the network. Even though Bitcoin's really successful, you're guaranteed to lose money if you buy the latest Antminer and run it at residential power rates. Meanwhile, Dogecoin back in the day had awesome profits even though it was a blatant fork of LTC with few improvements.
Your new RandomX rig might look like it has decent "ROI" to you, but that doesn't mean it was the best investment. You might have been better off building a GPU rig and mining Grincoin or Ravencoin. I.E. if you build a RandomX rig, you're earning less profit for the same amount of capital invested. And even if you earn the same return, you still took a higher risk than if you built a GPU rig (see the point above).
In the GPU mining community, I have the feeling that there's a lot of resentment over the 2018 crypto recession and the whole 'ASIC miner invasion'. I think people here are feeling burned over their losses last year and the evil ASIC takeover, and want an opportunity for the little guy to start mining again. So we're falsely seeing the RandomX ray of hope as a floodlight, and getting overexcited. And in general, the ordinary person cannot make a significant, steady profit in the crypto mining industry. The guy who wrote that thread is very rich and even 100 GTX 1080 Ti's cost nothing to him. The reason he became wealthy is because he avoided get-rich-quick gimmicks back in the day (like the dotcom sites) and focused on learning technology for the future. Mining will not make you rich, and especially not RandomX coin tossing. If you love RandomX, build your rig now, keep benchmarking and undervolting and have fun at it. But if you just want profit, wait until RandomX is up and running. And consider all the risks involved with a new algorithm and commercial mining in general. So I hope we can all reconsider whether we're excited about RandomX for the right reasons. Let's try to avoid jumping to conclusions about profitability and hold off on the Newegg 'checkout' button. Even though 12 cores at 70 watts sounds awesome. Happy mining!
Hi All, I’m new to this sub. After buying some bitcoin and watching it skyrocket I️’ve wanted to I️ learn more about crypto currencies. This has led to a lot of interest in bitcoin cash. I’ve wanted to pursue mining for a while but have no idea where to start? Is there a link or advice anyone could give to a first time miner to do it efficiently, safely, and securely? Maybe a previous poster has asked something similar you all would be willing to share. Thanks for the help!
THE END OF ALL ASIC MINERS? - Monero's New Superweapon: "Time Locked Proof of Non-ASIC work challenge reward" algorithms.
I propose the following algorithm to end this War of attrition with ASIC / FPGA manufacturers , hopefully once and for all and save us Precious PoW Tweaks during the upcoming forks.
"A time-locked, Proof of 'Non-ASIC work' Challenge reward algorithm"
Here's an image to help you visualise how the algorithm works (details below): https://imgur.com/a/9S8dA Here's why we need it: ASIC manufacturers mine in Secret to attack our decentralized network. They'll win the war since they'll 'get their investment back' before we brick their ASICs, allowing them to launch never-ending attacks against our decentralization, for eternity. Quick Overview This algorithm uses the concept of "time-locked reward challenges". The algorithm ‘time-locks’ the reward, then issues a ‘non-ASIC’ work challenge during each regular PoW Fork, which distributes mined rewards only to CPU and GPU miners who can pass the challenge and prove they are not ASICS, by maintaining their hashrate during the ASIC downtime. These Hash-rate challenges after PoW Forks successfully ‘detect’, and ‘Severely Penalize’ anyone Mining with an ASIC/FPGA, even those in Secret. Proof of Concept: An Actual Demonstration I'll demonstrate this algorithm in action: Please see this image to help you Visualise how the algorithm works: https://imgur.com/a/9S8dA There is a critical flaw and uniquely identifying feature that exists in absolutely 'ALL ASIC and FPGA miners', even those mining in Secret. As most of you may know, with the upcoming V7 PoW hardfork,
An ASIC miner’s hash rate component drops to Absolute zero for a set period of time afterwards, because their ASIC function can no longer be used with a PoW tweak.
Normal GPU and CPU miners are also very easy to identify; as they have no problem maintaining a relatively similar maximum hash rate after the fork.
Instead of just destroying an ASIC with a fork, we can further exploit this to attack the ASIC Manufacturer or Miner by taking back all their mined rewards and giving them to the community The Special timeframe is PoW Fork + 'N' Days. ('N' being however many days remaining where it would be "impossible" to build and startup a new ASIC/FPGA after the fork.) To exploit this, the algorithm introduces a period of time called the "Mining Rewards Collection Timeframe" (MRCT), the time period in between regular PoW Hardforks. the grey shaded area in this image This "Mining Rewards Collection Timeframe" is a time whereby all mining profit rewards are 'time-locked' or held hostage in escrow, on either the mining pool, or on the Actual Blockchain code itself, or Both, depending on where this algorithm is eventually deployed. The algorithm stores the wallet address a mining reward belongs to, and the maximum hash rate (or maximum value adjusted share rate per day) observed during the "Mining rewards collection timeframe" for that particular wallet address. This "Mining Rewards Collection Timeframe" can be of any duration as required by the developers; 1,2,3,4,5,6 Months or longer . The longer This Timeframe, the more dangerous it is to ASIC miners. Meaning we don't have to rush with forks. Since it's time-locked, mined coins/rewards cannot be cashed out until the coming challenge; However, mining pools can still choose to payout smaller miners before that time if they have a 'good stable Non-Asic Hash challenge passing history', or a deposit on file, or at their own risk, so most good miners don't have to wait to cashout rewards!. Big miners on the other hand, won't care! Why? Because the delay doesn't cost them anything. (it's a TINY TINY inconvenience compared to the damage ASICs would do to GPU mining profits. I hope this makes sense) Now for the Critical ANTI-ASIC Work Challenge. Time passes and the mining rewards collection timeframe ends with a Hardfork that changes the PoW algorithm slightly, All ASICS and FPGAs are INSTANTLY destroyed. At the same time, the mining rewards from that collection timeframe are now ready to be paid out. Since only the CPU / GPU miners are able to hash normally, The Algorithm now issues a Hash Rate challenge to determine how much of the coins mined were actually mined by ASIC or FPGA miners. The challenge is nothing special. Miners just have to leave their miners running normally at maximum speed for the period of the challenge, same as they do everyday! During this challenge, their "Average Maximum Hash rate during the challenge" is compared to the "Maximum Hash Rate speed" recorded on the blockchain during the Mining Rewards Collection Timeframe. See the green dotted line in the image Thus at this point, since ASICs are DEAD, they cannot Hash at the same rate during this challenge period, so any significant difference in hashrate would thus clearly indicate the use of an ASIC or FPGA miner. Now, we have all the information we need to STRIP ASIC Miners of ALL their gains, and Reward GPU miners instead. As shown in the earlier image
Example 1: A miner using PURELY 100% CPU and GPUs to mine, will easily pass the challenge as though it never happened. They can easily maintain 90% or more of their maximum hash rate recorded, well within the agreed margin of error. So they get the Full 100% Mining Reward, Plus a fair share of any of the coins forefitted by the ASIC Miners as a Bonus., (ie, 101% , or more.. possibly)
Example 2: A miner hashing with 100% ASICs or FPGAs, will be dead during this challenge and can match “0.00%” (ie, Nothing) of their maximum hash rate observed. As such, they proportionally also get “0.00%” of the rewards they mined and forefit all their rewards to other miners.
Example 3: A miner hashing with 60% ASICs and 40% CPU/GPUs will only be able to maintain 40% of their Maximum hash rate during the challenge period. As such, they proportionally only get 40% of all the Mining rewards they earned and forefit and Lose the 60% of all coins mined by the ASIC miners.
What if a 1 GPU breaks in a 12 GPU mining farm during the challenge? (Very rare) or for some reason, you can't mine during that period? then the miner can simply rent the GPUs from nicehash for the Challenge. An ASIC miner however, cannot use this strategy (because ASICS are not GPUs, explained further below). Also we can implement a 2nd chance option; the confiscated reward may be frozen for the next Cycle; and the miner may get a 2nd chance to prove the hashrate again, with a % reward penalty. The Beautiful thing is that If ASIC miners fail the challenge, Everyone gets a Bonus share of the Reward Forefitted by the ASIC miners, So Everyone wants the ASIC miners to fail so they get Free extra money. and thus have a financial reason to support this algorithm. *There is no escaping it... or is there? Is it ASIC PROOF? Can you Cheat this algorithm? I've also tried to see if you can work around this algorithm:
Example 1: What if they switched in GPUS to mine for an ASIC during the challenge? Well, that wouldn't work. When the challenge comes, they can either save the rewards mined by the GPUs, or save the rewards mined by the ASICs, One will always be lost and result is the same anyway because you'd only get paid for the Hash rate of the GPU. The ASIC portion of the hash rate will ALWAYS be lost.
Example 2: What if they use the GPUs to mine a different coin and have them only hash for the ASIC during the challenge period?
Consider the Antminer X3. at 200KH/s, to support just "ONE ASIC", they would need over 200 RX 580 Cards or 100 VEGA cards to pass the challenge... costing well over $60,000 (SIXTY THOUSAND DOLLARS) and if they depreciate at ~ 10~15% a year, they'd lose $6000~$9000 a year. it's not enough to cover your losses,
Also, What other coin could you mine? If ASICS are so powerful, there won't be another coin except those running this algorithm. Then, the dev can choose to issue the challenge at the same point as the other coin using the same algorithm, so they lose all rewards from one coin as 1 rig cannot sustain two challenge algorithms at the same time.
Example 3: What if they just leave some GPUS on standby to avoid the power costs? Then ASIC's would still be unable to be mass produced anyway. Because for every ASIC Mass produced, you'd need to Mass Produce 200 times the GPUS to support them in their place, and own of all them. practically impossible.
Example 4: What if they rented hashing power from Nicehash to fill in during the Challenge period?
Yes, but so can we! The beautiful thing about this algorithm, is if we rent the limited hashing power on Nicehash first before them at break even or loss, it doesn't matter, Because, the ASIC miner cannot rent and hash rate and will fail the challenge, and Forefit the ENORMOUS amount of Rewards to the community. Imagine, Mining at such a high rate for months on end , the rewards confiscated and paid to GPU miners will easily offset any of the tiny losses renting hashrate from Nicehash, so ultimately, The ASIC miners lose Everything, and the community (you and me) gets all their money.
Also if ASICs Dominate the crypto market, there won't be any GPU to rent, all remaining coins would be mining this algorithm, meaning they would have to save their own hashrate for themselves, not rent it to ASIC miners. otherwise they lose their reward. Brand new users may rent their GPU's but its no where near enough to cover the ASIC hash shortfall in the challenge.
Example 5: What if they waited till we exhausted our supply of PoW fork tweaks? That's the beauty of this algorithm!. We don't actually have to tweak the PoW algorithm on a constant basis! We can intentionally leave it the same. So Everyone passes the Challenge, Then when we do detect an asic "trying to Mine their Money Back in secret (as they do now)", We tweak the PoW at the Next Hardfork. Destroying and bankrupting their very first attempt, and we get all their money and rewards, So there's no need to waste a PoW tweak in a pre-emptive strike, because the rewards are Time-Locked to the future. We can lie in wait with a single PoW like a Trap, and eat them alive (literally we get all their rewards after the challenge!). We can maintain this lethal threat to ASIC manufacturers without having to change the PoW at all!
And remember, all this effort is just for ONLY, ONE ASIC. meaning you Can't mass produce it. So ultimately it wouldn't even make sense to even develop an ASIC, as you'd be far more profitable just mining only with the 200+ GPU's required to cheat the algorithm. *So in summary, *
No ASIC/FPGA miner can escape the challenge. Not even those running in secret.
All ASIC miners are guaranteed to suffer a huge (possibly fatal) financial loss, with no prospect of any return on investment. Time locked rewards ensure No secret pre-mining with ASICs is possible. ASICs are destroyed with each challenge, all R&D and manufacturing costs and the electricity bill used to power them is wasted for basically "ZERO returns",
…..and lets not forget that all their rewards gets given away to other honest miners like you and Me!. ( LOL!) or potentially the developers of the fork :)
As long as the algorithm is active and used by multiple coins, no ASICs will ever exist to mine in secret,
We save precious PoW tweak changes, since there's no need for a pre-emptive PoW strike to prevent 'ASIC hit and run' pre-mine scenarios.
ASIC manufacturers see that the war is un-winnable and go invest in other things,
So, in theory, The War Ends. (at least for a very good part of the future) As they say: " Don't build a wall and hide in fear.... Build a wall and launch missiles from behind it against the enemy so they will never dare attack us again." I would like to point out that time locked reward challenges are already in use by the Olympic games to Strip drug cheats in the past by storing samples and testing them in the future, and it's also in the PPLNS minig pool algorithms to deter pool hopping cheats, and also in the Bitcoin's Lightning network in the form of decrementing time-locks" that 'enforce the transfer of funds' under certain conditions. Is it beautiful? Will it work? Can it be done? Let's discuss this
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.
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.

It is understandable that Bitmain don’t want their customers to change overclock on their asic miners. OC changes could possibly kill or damage hardware in some cases when chip oc and voltages applied to much. Overclock could kill miner it self or power supply. This is one of the reasons why Bitmain lately locks down their miners firmware, they dont want customers to do any changes on them. The factory settings are standard, whoever is mining for while now. Knows that from some chips you can get better efficiency, just because quality of every chip is not the same. Lately there is been released an upgrade firmware and manual for Antminer S17 from hiveOS. HiveOS is gpu and asic miner monitoring/remote control. They previous firmware for Antminer S9 and T9 has been very successful. We have done review on this firmware also, and the best feature what Bitmain original firmware does not have is auto-chip tuning. It works very well, basically it finds the most optimal chip oc and the voltages to reach best efficiency. https://preview.redd.it/ewt2x2v59id41.jpg?width=1702&format=pjpg&auto=webp&s=008de1118c5721a4844cf90c25e4f1fc72b71b73 We have now also tested the new firmware for Antminer S17, it does perform much better then Bitmain original firmware.OnAntminer S17 53TH/s version , air cooled miner we where able to reach 75TH/su/3300watts. It worked very well and setup is straight forward. It is possible to reach even better performance up to 85 TH/s , but you will need immersion cooling. As with air cooled at 75 th/s our miner chip temperatures where close to 80c at room temperature 15c. Also be careful , Bitmani stock power supply Antminer S17 max power usage is 3500 watts. https://preview.redd.it/vwovczl69id41.jpg?width=1952&format=pjpg&auto=webp&s=211b252bd225b1dc7e35195bc86c823b2e2ad7ad hiveOS asic miner the installation guide :
And now let’s go back to the installation process. There is no universal manual, for S17 and S17 Pro there are 3 versions of stock firmware. Therefore, every particular case has its own manual on the custom firmware installation. Please note, that all the manual steps which involve using BTCTOOLS can be done via ASIC’s web interface (BTCTOOLS is usually used for a large number of devices).
Scan the network using BTC_TOOLS and export the list to csv. From csv, copy the IP list and insert it in ips.ini. In case you don’t have a lot of devices, you can make this list manually. Or use bitmain ipreporter tool.
Go to config.ini and check login and password for the ASIC’s SSH or web interface. If the password for the web interface was changed, the same would be for SSH. Set up FARM_HASH to connect to Hive or API, if necessary.
If the stock firmware of your ASIC is released before 1 July 2019
Flash your devices with a file from the archive “remsigallbefore_2019–07–01.tar.gz”. This can be done via either ASIC’s web interface or BTC_TOOLS in case you have a lot of devices. You will see an error in status, but this is okay — it should be like this at the moment.
Flash the devices with the firmware file. Again, this can be done via either ASIC’s web interface or BTC_TOOLS.
Launch “3hashfarmforsigned.cmd” from the archive. The ASIC will get connected to the web.
Stock firmware released from July 2019 to December 2019
Launch “1openssh.cmd” from the archive and wait for the script to be performed. The devices will be rebooted. After the reboot, wait for around 3 minutes.
I started mining bitcoin in the desert. Here's some of what I have learned.
I started a vertical farm out in the Southern California desert nearly a year ago. It is a modern, solar-powered aquaponic farm. We are 100% off-grid and currently use only solar. Since we are totally off-grid, we need to produce (and store) additional energy for those days of no sun. But since we are in the desert, we rarely need this excess energy. So, we have been mining bitcoin with this excess solar energy. And I have some interesting data. I can tell you that for about every 23 cubic meters (about 800 cubic feet) of our greenhouse, we can install one Bitmain Antminer S9. We are currently generating almost 4 bitcoin per year from each Antminer. I am building my farm out to 1,000 square meters of greenhouse space, at a height of 10 meters. So it will support about 425 miners. The nice thing about mining bitcoin using the excess energy from my farm is that I must produce it regardless. So I think this is the ABSOLUTE maximal use of my excess energy production. Just because I like to share (and literally no one here will copy my idea), we make about $100 per cubic meter in NET PROFIT from farming vertically each month. And about 0.014 bitcoin per cubic meter per month ($12.50 currently). I am going to build about 100 small greenhouses this year. Each greenhouse can support 4 miners. I think I am going going to order a million bucks worth of miners and start mining for real. Thoughts? For the record, I already know it is crazy....so don't waste your time with that one. Can anyone come up with a better use of free extra energy? I have been trying to come up with one for the last year.
Bitcoin Mining Power Sees Short-Term Drop as Rainy Season Ends in China
https://preview.redd.it/84jk6ssun2w31.png?width=1024&format=png&auto=webp&s=e11e42aea4b0346f9e2548bc0b0191dd0a966c90 After sustained growth over the past three months, computing power on the bitcoin network has seen a fallback as the summer rainy season trails off in China. According to data from Poolin, the world’s largest bitcoin mining pool by real time hash rate, bitcoin’s seven-day average computing (or hashing) power has dropped to around 90 exahashes per second (EH/s) since Oct. 24, signaling that some miners have been unplugging from the network. It had previously been estimated that the hash rate would go above the 100 EH/s threshold by the end of 2019 As a result of the power drop, data from mining pool service BTC.com estimates that bitcoin’s difficulty – a measure of how hard it is to compete for mining rewards on the world’s top cryptocurrency by market value – will decrease by 1.5 percent when it’s set to adjust in about seven days. Bitcoin’s mining difficulty had reached an all-time-high at 13.69 trillion on Oct. 24, following a 38 percent increase since early August. The climb resulted mainly from an increase in miners’ hashing power made possible by the abundant and cheap hydroelectricity in China’s southwestern provinces. Mining difficulty is designed to adjust itself to go up or down about every 14 days, based on whether the hashing power on the network in the two-week cycle increases or declines, respectively. The Oct. 24 difficulty record followed a jump in the 14-day average hash rate to an all-time-high at 97.90 EH/s. Poolin’s co-founder Chris Zhu said in a recent WeChat post that one main reason for the fallback over the last week is the gradual end of this year’s rainy season in China. As a result, some hydropower stations in China’s Sichuan province – estimated to account for 50 percent of bitcoin’s global computing power – no longer have the capacity to generate enough energy to support mining activities. Miners without sufficient hydropower supply would have to shut down their operations or relocate to other provinces like Xinjiang or Inner Mongolio, where mining farms have a more stable, but more expensive, power supply generated from fossil fuel plants. Xun Zheng, CEO of Hashage, which owns mining facilities in China’s southwestern Sichuan province, echoed Zhu’s comments, adding that even if some may still be able to find a hydropower resource, the cost has gone up from $0.04 per kilowatt-hour (kWh) in the summer to around $0.05. Further, bitcoin’s sudden price drop on Oct. 23 to below $7,500 could have resulted in a large scale of shutdown of older but widely used mining models like the AntMiner S9 made by Bitmain. The S9’s profit break-even price point is between $7,000 to $7,500. However, the price’s significant rebound since last weekend may have stopped that panic. The fact remains, though, that the profitability of the S9 and other similar modes made by Bitmain’s rival miner makers, is a critical issue for their utility lifespan. And that may soon be affected by the higher winter cost of electricity in China, as well as the scheduled halving of bitcoin mining rewards in May 2020 – before next year’s rainy season. According to a miner profitability index provided by Poolin and its rival F2pool, at bitcoin’s current price and an electricity cost of $0.05 kWh, the mining profit margin of models like S9 is about 30 percent. Some, like INBTC, a sister company of Poolin, are currently making efforts to extend the life of the S9 miner by merging two units into one in an attempt to generate a higher ratio of hashing power over electricity consumption. That would allow a higher daily profit margin than would be achieved using two individual units, though it remains to be seen if such a method can be proven to work and adopted on a large scale.

First time I heard about bitcoin in 2017. My friends from the Bay Area told me to read about it. I started with googling and watching YouTube videos. It was interesting and I bought a couple of books and divided to crypto history. From the very first moment I felt that this technology is promising and I was excited about it. While I was looking for ways to buy bitcoin, the price was climbing up every week. So, I decided to research more until the end of the year and not to rush. After I read about mining, I was thinking about how to set up my own rig. I found a local guy who promised to help, but there wasn’t any single GPU on the market. To get 6 for set up you had to wait for a month and pay too much. Antminers at that time cost more than $4500 per unit from resellers. It was really crazy times. So I didn’t find an adequate way to enter the market and decided to wait. While waiting I watched dozens of YouTube videos on mining and read a lot of articles. Till the moment I first bought my miners I was consuming knowledge. And finally, in May 2018, I bought my first 20 ASICs. I immediately launched them at my friend's place. In the beginning, there was a problem with the hash rate, as we were still learning how to set up proper internet and power supply. In practice, we were intensively improving the facility, as we wanted to get maximum out of mining. After a month and a half we decided to expand and made bulk order directly to Bitmain. Prices dropped nearly 35%, so we thought it was a good idea to buy more, as we gained experience with facility management. At the same time, my friends asked me whether I can host and manage miners for them if they buy some. I said yes, but offered a fee for hosting. That’s how my hosting business started. And it grew rapidly since that time. As not only my friends were interested, but later I met a lot of international miners, who came to my country in search of cheap electricity. I started to think globally and understood the existing problem on the market. As prices of crypto declined significantly, in many places mining became unprofitable. That caused the migration of mining equipment to cheaper places. Expansion of hosting forced me to rent a separate facility and connect 2 MW from power plant directly. That was made to decrease electricity price and operational costs, which in turns resulted in even cheaper rates for hosting. Sometimes my international potential clients cannot believe how can I provide such cheap hosting fee. Even here some people in comments say it is a scam. But the reality is that the level of life is so low, that this cheap electricity is really expensive for locals. Not everybody lives and gains salaries like in EU or USA. The biggest challenge for crypto mining now is finding ways to make it more efficient and decentralized. Many companies building huge mining farms in locations without gaining access to the cheapest electricity. Big companies gaining more strength which lead to more centralized mining. I prefer having a lot of different miners all over the world, instead of, for example, Bitmain controlling 40-50% of hash power. In the end, we all must contribute and try to improve the beauty of crypto.
