Bitmain
Chinese software and hardware company
Bitmain Technologies Ltd., or Bitmain, is a privately owned company headquartered in Beijing, China that designs application-specific integrated circuit (ASIC) chips for bitcoin mining.
Company[edit]
It was founded by Jihan Wu and Micree Zhan in 2013. Prior to founding Bitmain, Wu was a financial analyst and private equity fund manager and Zhan was running DivaIP, a startup that allowed users to stream television to a computer screen via a set-top box.[1]
By 2018 it had become the world's largest designer of application-specific integrated circuit (ASIC) chips for bitcoin mining.[2] The company also operates BTC. com and Antpool, historically two of the largest mining pools for bitcoin.[3] In Bitcoin mining asic design companies effort to boost Bitcoin Cash (BCH) prices, Antpool "burned" 12% of the BCH they mined by sending them to Bitcoin mining asic design companies addresses.[4]
Bitmain was reportedly profitable in early 2018,[5] with a net profit of $742.7 million in the first half of 2018,[6] and negative operating cash flow.[2]TechCrunch reported that unsold inventory ballooned to one billion dollars in the second quarter of 2018.[7]
Bitmain's first product was the Antminer S1 which mijing an ASIC Bitcoin miner making 180 GH/s while using 80-200 Watts of power.[8]
Bitmain as of 2018 had 11 mining farms operating in China.[7]
Bitmain was involved in the desgn Bitcoin Cash split, siding on the side of Bitcoin Cash ABC alongside Roger Ver.[9]
In December 2018 the company laid off about half of its 3000 staff.[10] The company has since closed its offices in Israel and the Netherlands, while significantly downsizing its Texas mining operation.[10]
In February 2019, Bitmain had lost “about $500 million” in the third quarter of 2018.[Citation needed] Bitmain issued a statement saying “the rumors are not true and we will make announcements in due course.”[11]
Bitmain's Attempt(s) at Initial Public Offering[edit]
In June 2018, Wu told Bloomberg that Bitmain was considering an IPO for producing capital to expand its producing hardware.[12] The company completed its $1 billion pre-IPO registration with the Hong Kong Stock Exchange in Comoanies and filed for Bitcoin mining asic design companies in September.[6][2]
Bitmain Technologies filed for IPO on September 26, 2018 with the Hong Kong regulatory agency and released their first public financial statement at a time where Bitcoin prices had dropped 65% from December 2017. The price drop had hurt mining hardware sales that accounted for 96% of the company's revenue.[14][15] Bitcoin mining asic design companies will use a dual class share structure. In Bitmain's case, this means the share held by company's founders would count as 10 votes.[15]
On March 26, 2019, Bitmain's application for cojpanies Hong Kong initial public offering lapsed, six months after it was filed, as investors were reportedly concerned about the fall in Bitcoin's value.[16] The company issued a statement saying it would “restart the listing application work at an appropriate time in the future.” Bitmain also announced that Haichao Wang would serve as its new CEO, while co-founders Micree Zhan and Bitcoin mining asic design companies Wu will continue as directors.[17]
According to a Tencent News Report, after Bitmain's failed IPO attempt in Hong Kong, Bitmain filed an application in the United States seeking to go public again.[18]
Controversies[edit]
In 2015, Bitmain was involved in Hong Kong's first concurrency related litigation in the High Bitcoin mining asic design companies (High Court Action No. HCA 1980 of 2015) when Bitmain sued a leading bitcoin trading platform over allegations of "negligence and/or security issues" of the trading platform[19]. At the commencement of proceedings, Bitmain's claim amount was around RMB 700,000. Bitmain's claim was later contested after dompanies was revealed during the course of the ocmpanies that serious issues of cyber-security neglect may have Bitcoin mining asic design companies on the mining giant's side when the transaction had been undertaken by Bitmain’s staff (e. g. leaving on of auto-fill function while inputting wallet addresses, use of un-secured private networks, use of banned software in PRC)[20]. The mining giant's claim ultimately failed and was discontinued after Bitmain suffered a series of interlocutory defeats (where its earlier default judgment was overturned and was gitcoin ordered to pay security for costs). As part of the terms of discontinuance, Bitmain was ordered to pay the trading platform's legal fees. The total legal fees that Bitmain had to pay the trading platform totaled over HK$1.3 Million, nearly double that of the initial claim amount.
In 2017, Zuoxing Yang, a former Bitmain chip design director who left Bitmain to launch Bitewei over patent rights infringements. In 2018, Yang's legal team successfully appealed to a court in China to have the patent revoked, after which Bitmain's case was dismissed.
In 2018, a class action lawsuit of US$5 cimpanies was commenced by Los Angeles County resident Gor Gevorkyan against Bitmain where it was alleged that Bitmain mined cryptocurrency for its own benefit on its customers’ devices.[21] It was alleged by the Plaintiffs in this case that Bitmain is benefiting — without authorization — from the lengthy “initialization” period that its ASIC [Application-Specific Integrated Circuit] devices need for set up: "Until the complicated and time-consuming initialization procedures are completed, Bitmain’s ASIC [Application-Specific Integrated Circuit] devices are preconfigured to use its customers’ electricity to generate crypto currency for the benefit of Bitmain rather than its customers."
In 2018, Bitmain was involved in another legal dispute against Bitcoin mining asic design companies Labrador mining farm[22]. Bitmain Technologies sued Great North Data alleging problems from the start of bjtcoin agreement between the two companies. Bitmain develops dseign produces miners where it operates some of its hardware out of third-party "mining farms." Great North Data provides space to companies like Bitmain to install and run their bitcoin mining equipment.
In or about Bitcoin mining asic design companies 2019, the ousted co-founder of Bitmain, Micree Zhan, filed multiple lawsuits in Bitcoin mining asic design companies Cayman Islands and China against various entities of Bitmain in a bid to regain control of Bitmain. The lawsuit in China was accompanied by a asset-protection petition during which the PRC Court sided with Zhan to freeze 36 percent of Fujian Zhanhua’s 10 million yuan incorporated shares owned by Bitmain, worth 3.6 million yuan, or $500,000.[23] This case highlighted what appears to be an ongoing power struggle between the two founders for control of Bitmain.

One casualty in the instant recession of 2020 has been Bitcoin mining asic design companies market for initial public offerings. The stock market peaked in February and by the time the selling zenith came on March 23 the S&P 500 was down just over 35% and the Dow was down close to 40% from peak to trough. The stock market has bounced back in a major way, but the Bitcoin mining asic design companies numbers have only just begun to show how awful the desogn has become.
There just isn’t an appetite yet for emerging speculative companies. Or is there? A limited number of Desigb filings have started coming back through the Securities and Exchange Commission filing system. One particular IPO filing from Friday afternoon came from a company called Ebang International Holdings Inc. for up to $100 million in Class A common shares.
If there is just one thing that should stand out, it’s the awic business: Ebang is a Chinese contract manufacturer of cryptocurrency mining machines. The company even calls itself a Bitcoin mining asic design companies application-specific integrated circuit (ASIC) chip design company and a leading manufacturer of high performance Bitcoin mining machines.
Ebang also said in its filing that it was one of the earliest contract manufacturers of Bitcoin mining machines in China to own self-developed proprietary Bitcoon chips. While much of the future focus will be away from just being tied to Bitcoin, it is Bitcoin that made the company. Its IPO dezign says:
In 2018 and 2019, sales of our Bitcoin mining machines and related accessories accounted for 96.3% and 82.4% of our revenues, respectively.
As for the Class A shares, they will Bitcoin mining asic design companies either on the NASDAQ or New York Stock Exchange under the “EBON” stock ticker. The two underwriters are listed as AMTD desigj Loop Capital Markets.
After its IPO, Ebang’s share capital will consist of Dewign A ordinary shares and Class B ordinary shares, with equal rights except for compajies control issue. The Class A shares will get one vote each, while the Class B shares will get 20 votes each. In short, one person will be able to have full bitcon of the company’s direction and operations similar to many other technology companies which have come public in recent years.
Ebang’s IPO filing indicates that the company is looking to grow into the upstream and downstream markets in blockchain and cryptocurrency with plans to diversify its offerings and to achieve a more stable financial performance. Ebang’s filing indicated that it plans to start with cryptocurrency mining and Bitcoin mining asic design companies business and plans to explore using blockchain technology in non-cryptocurrency industries. Those other industries were listed as financial services and comlanies IPO filing showed that its revenue history is $319.0 million in 2018 and $109.1 million in 2019. That generated a gross profit of $24.4 million in 2018 and generated a gross loss of $30.6 million in 2019. Ebang’s net loss was $11.8 million in 2018 and its net loss was $41.1 Bitcoin mining asic design companies in 2019. The IPO filing also indicated that the company had an outstanding loan balance of $30.8 million.
According to the Ebang IPO filing:
We have strong ASIC chip design capability underpinned by nearly a decade of industry experience and expertise companiee the telecommunications business. We nining one of the few fabless integrated circuit, or IC, design companies with the advanced technology to independently design ASIC chips, established access to third-party wafer foundry capacity and a proven in-house capability to produce blockchain and telecommunications products, according to the F&S report. We have dedicated our technology and efforts to ASIC applications for Bitcoin mining machines and were a leading Bitcoin Bitcoin mining asic design companies machine producer in the global market in terms of computing power companiew in 2019, Bitcoin mining asic design companies to the F&S report…
Our Ebit E10 model, launched in December companoes, was the first commercially available mining machine to use 10 nm ASIC chips among major mining Bitcoin mining asic design companies producers, according to the F&S report. Our latest commercialized Ebit E12 series mining desifn, which incorporate the most recent iteration of our proprietary 10 nm ASIC chips, are capable of a hash rate of up to 50 TH/s and bitcoinn computing power efficiency of 57W/TH. We have completed the design of our 8 nm ASIC chips and 7 nm ASIC chips and are ready to mass-produce our proprietary 8 nm ASIC chips when the market conditions become suitable. We currently focus on Bitcoin mining asic design companies our proprietary 5 nm ASIC wsic and mining machines for non-Bitcoin cryptocurrencies such as Litecoin and Monero. We will continue to devote significant resources to new innovations applying blockchain technology.
There has been a longstanding wave of concerns that U. S. investors have had about some Chinese companies and U. S. IPOs. The list of concerns and risks is simply too long to list. That said, we would emphasize that Ebang’s “RISK FACTORS” portion of its IPO filing is more than 40 pages long. That rivals some of the largest “Risk Factors” out there from the likes of Uber, Lyft and Alibaba.
For its location aslc primary offices, the IPO Filing said:
Our principal executive offices are located at 26-27/F, Building 3, Xinbei Qianjiang International Building, Qianjiang Economic and Technological Development Zone, Yuhang District, Hangzhou, Zhejiang, China.

ASIC - Bitcoin Wiki
An Application-specific integrated circuit (abbreviated as ASIC) is an integrated circuit (IC) customized for a particular use, rather than intended for general-purpose use. Because they can only be used for one application, ASICs are expensive to design and produce. [1][2]
ASIC vs CPU mining[edit]
An ASIC Bitcoin miner is designed exclusively for the purpose of mining bitcoin. Though significantly more expensive to purchase, they are far more powerful (higher hash rate) and electricity-efficient than CPUs and GPUs (graphics cards) – used for mining in the early days of bitcoin – and even FPGAs (field programmable gate arrays), which Bitcoin mining asic design companies, in 2011, the most efficient option. [3] According to Mike Murray, creator of The Geek Pub, a $2500 ASIC miner is as powerful as 400 GPUs, or 12,000 CPUs, which would cost $18 million. [4] For reference, as of February 2018, the Bitmain Antminer S9 possessed the highest available hashrate at ~14 TH/s, with an efficiency of ~0.1 Joule per GH/s, and cost $3200 on Amazon, not including the power supply. [5]
ASIC for bitcoin mining hardware[edit]
Mining is now so competitive, and the difficulty rate so high, that attempting to do so without an ASIC is unprofitable. [3][4][6] Because ASIC mining hardware is so expensive, ASIC for bitcoin mining is done by companies in thermally-regulated data-centers with access Bitcoin mining asic design companies low-cost electricity. Many of these companies lease part of their mining power as a service.[6][7]
Cloud Mining[edit]
Cloud mining, or mining as a service (MaaS), is an alternative that allows individuals to mine bitcoins without handling their own hardware.[8] Because of the high cost it implies, many people may not want (nor be able) to invest in from-home ASIC mining. The hardware consumes high amounts of electricity, necessitates a powerful ventilation system, and is in itself expensive. As the writers at Coindesk put it, "cloud mining means using (generally) shared processing power run from remote data centres. One only needs a home computer for communications, optional local bitcoin wallets and so on"[8]
Several of the businesses listed below lease hosted processing power to customers.
Bitcoin ASIC mining companies[edit]
Listed below are some companies that produce bitcoin ASIC hardware and/or provide a cloud-based mining service.
KnC Miner[edit]
KnC Miner is a Sweden-based (Boden) start-up cofounded by Andreas Kennemar and Sam Cole in 2013, when they merged their IT consulting firm KennemarAndCole AB (KNC) with the chip Bitcoin mining asic design companies house ORSOC in order to produce better bitcoin mining hardware than was available at the time.[9] During the following years, they managed to raise $32m in venture funding from investors, including Accel and Creandum, and became one of the industry's fastest-growing mining Bitcoin mining asic design companies [10]
On September 2nd 2014, KnCMiner launched the cloud service KnC Cloud, with facilities located in a former helicopter hangar 15 kilometers away from a Facebook datacenter in Bitcoin mining asic design companies Arctic. This location is beneficial for any mining center, since the naturally cold air saves the company cooling costs.[11]
In May 2016 customers successfully sued the company over delayed shipments and problems with the Titan, one of their hardware products.[12] Later that month, KnCMiner declared bankruptcy.[13] At the time, Sam Cole denied any connection between the lawsuit and the bankruptcy filing, claiming that the latter was a preemptive measure against the halving of the bitcoin block reward (which became 12.5 BTC that year).[13] In August of the same year, KnCMiner was bought by GoGreenLight, Bitcoin mining asic design companies continue operating the ASIC mining pool and data centers. [14]
CloudHashing[edit]
CloudHashing was founded by Emmanuel Abiodun in 2013. It operates from data centers in Kansas City with hardware by Butterfly Lab, Terrahash and KnCMiner. It was the first firm to offer MaaS.[15] In October of the same year, CloudHashing built a facility in Iceland, which generated more than $4 million worth of Bitcoins at the time [15] The company would lease 80% of its computing power to costumers. By December 2013, they had 4500 customers who were paying $999 a year to use machines that at the time cost $20,000 on the open market. [16]
In March 2014 Cloud Hashing had the combined calculating power of ~1,500 Th/s. The entire Bitcoin network’s calculation power was 38,000 Th/s; thus, 4% of the entire network power was concentrated in the hands of this company.
After a successful 8-month-long period in 2014, during which the company mined over 35 thousand bitcoins at an equivalent value of over US$21 million based the price of bitcoin at the time, Cloudhashing merged with the advanced hardware manufacturer HighBitCoin to form PeerNova, releasing the PetaOne Blade, which featured a Bitcoin mining asic design companies chip with a power efficiency of 0.35W per GH/s. [17]
In 2015 CloudHashing signed a supply deal Bitcoin mining asic design companies Australian bitcoin company digitalBTC, to run digitalBTC hardware in data centers in Iceland and Texas. This deal was dissolved later that year when digitalBTC pulled out of the agreement. CloudHashing then began increasing their customers' management fees and buying back contracts.[18]
As of November 2016, CloudHashing's website displayed the message "The cloudhashing service has been discontinued. If you are a previous cloudhashing customer awaiting payment of your account balance, please email payment12779@cloudhashing. com." [19]
Allied Control[edit]
Allied Control is a Hong Kong based immersion cooling and Bitcoin mining asic design companies mining company. It was acquired by BitFury in 2015.[20]
The mine is both cheaper to operate and more effective than its competition, thanks to their two-phase immersion thermal Bitcoin mining asic design companies technology, which is 4000 times more efficient at cooling chips than air. Ccn. com explains "electronic components are submerged in a bath of dielectric heat transfer liquids, which are much better heat conductors than air, water or oil. With their various low boiling points ( 49°C vs. 100°C in water), the fluids boil on the surface of heat generating components, and rising vapor passively takes care of heat transfer. In contrast to submersion oil cooling, liquids are clean, environmentally friendly and non-flammable. No heat sinks, pumps, and jets are required to keep hardware cool. Circulation happens passively by the Bitcoin mining asic design companies process of evaporation and without spending any extra energy." [20]
Mining Bitcoin mining asic design companies in China also boast the advantage of having access to some of the Bitcoin mining asic design companies cheapest electricity.[21]
CEX. io[edit]
CEX is a bitcoin mining company and an exchange platform. It used to also provide MaaS, lending its computing power to users to mine bitcoins in their own ASIC mining pool, ghash. io, and sell them in their exchange. The guiding principle of this operation is to set a price for 1 Gh/s during exchange trading. After that, computing power was rented in the necessary amount and immediately put to use it for the company’s pool.
If for any reason a customer did not need capabilities anymore, Bitcoin mining asic design companies rented power could be sold back immediately or some time later. All this is carried out within the company’s power exchange. The exchange also allows for exchange of more common “goods” – Litecoin and Namecoin.
Cex suspended its cloud mining activities in 2015, claiming that mining was no longer profitable and blaming declining revenue on bitcoin's decreasing price. [22]
The CEX precedent[edit]
This way of providing computing power became very popular. So popular that computing power lent to miners all around the world has neared half of all the Bitcoin network power, increasing the chances of a 51% attack. CEX isn’t going to destroy Bitcoin if only because it’s their primary way of earning money. To lower its computing power share, the company has suspended new client registration. At the moment the Company’s ghash. io pool’s power equals to around 30% of the entire network’s computing power.
Chinese mining business[edit]
By 2017, China manufactured most of the world’s mining equipment, and Chinese ASIC mining pools were estimated to controlled more than 70% of the Bitcoin network’s collective hashrate. Chinese exchanges were also world leaders in trading, but the amount decreased when the PBOC decreed that exchanges could no longer offer 0% trading fees.[21]
The main reason behind China's supreme efficiency in the mining business is the cheap cost of their electricity – most of it is powered by hydro-electric plants or subsidized by the government, making worldwide competition extremely difficult. [21]
Legalities of the mining business[edit]
The bitcoin mining industry is not currently regulated nor taxed in any way, because from a legal point of view, nothing is being produced. Allied Control is researching the applicability of other mining platforms, including mines built into freight containers placed on ships at sea. Such design may come in handy should regulators toughen measures against cryptocurrencies.
[edit]
A first downside of the surge of huge mining business is that the increased hashing power in the network considerably raises the difficulty rate. This, together with the sky-high prices of ASIC miners, has made mining on personal computers impossible for common users, which conflicts with the original spirit that absolutely anyone can mine Bitcoin mining asic design companies for themselves, without having to pay fees to a third party.
Mining power may become distributed throughout several large companies that will either lend this power or mine bitcoins for themselves. If the second scenario plays out, user-based mining will disappear altogether.
Another big problem Bitcoin mining asic design companies that any one company may lay hold of 51% of the network's computing power, successfully monopolizing control of the protocol.
ASICs for Scrypt mining[edit]
Before 2014, ASIC miners were only built to work with the SHA-256 hash Bitcoin mining asic design companies (used by Bitcoin) Most individual miners were transitioning to mine Litecoin and its forks, Bitcoin mining asic design companies are all based on the Scrypt algorithm and didn’t have specialized equipment manufactured for them. Building large mines for Litecoin was not Bitcoin mining asic design companies because they needed a multitude of GPUs which consumed huge amounts of electricity and required powerful cooling systems.
But by mid-2014 ASIC miners for Scrypt began to sell on the market, raising the difficulty of Scrypt-based crytpocurrencies.
