⑴ Can anyone tell me whether you will lose money in blockchain transaction mining?
Losing money is possible under any circumstances. There are no hundreds of people in this world. Investments that can make money are 100% sure to be made.
With the rise in the price of Bitcoin, the mining industry has become a veritable "gold mine". The large influx of newcomers and retail investors has made the Bitcoin market
Coin mining machines are hard to come by.
It is precisely in the face of such a market that the price of Bitcoin mining machines has also begun to rise. Not only that, because the number of Bitcoins is becoming increasingly scarce
, so mining The difficulty is getting bigger and bigger, and now the production capacity of Bitcoin mining will gradually decrease.
When the revenue of the mining machine is not enough to pay for the electricity consumed, the currency price at this time is called the "shutdown currency price". The influencing factors include currency price, electricity consumption
price, mining Mining difficulty, etc., if the currency price falls below the "shutdown currency price", miners need to shut down the mining machine, otherwise they will lose money.
So, any industry has certain risks, and only when you devote yourself to this industry, that is, after you have a deep understanding
, will you know There are risks involved, and you need to bear these risks before you can continue to develop in this industry.
Blockchain mining:
In 2009, Satoshi Nakamoto invented Bitcoin and set a limit of 21 million Bitcoins. In the Bitcoin network, by participating in the production of blocks and providing proof of work (PoW), you can obtain rewards from the Bitcoin network. This process is mining.
The concept of "mining" is taken from the existing concepts in our real economic life, such as gold mining, silver mining, etc., because minerals are valuable
That’s why people are driven to pay labor to dig.
Another important point in Bitcoin mining is that the miners participating in mining recognize the value of Bitcoin, and there are people in the market who are willing to mine the Bitcoin market
Spend money. So, Bitcoin mining makes sense.
⑵ Crazy blockchain, crazy mining machines
After the recent climax of Bitcoin’s rise, Ethereum’s performance followed. Ethereum’s OTC transactions have now exceeded 10,000 . And the mining craze triggered by the skyrocketing rise of these mainstream currencies has also reached its climax.
Recently, the market for Bitcoin mining machines and graphics card mining machines has also been extremely short of stock, and many miners have increased their prices to buy but may not be able to buy mining machines. Now there is a price but no market.
Recently, a friend and the boss of the general agent of graphics cards in China are developing graphics card mining machines. I have built some graphics card mining machines with him before, and also hosted several Bitcoin mining machines with Jin Wei. machine. I have a little understanding of mining machines, and I just happened to calculate the cost performance and cost cycle of these two mining machines for my friends in the past two days. Let’s do the input-output analysis of these two mining machines.analysis.
The following is a calculation and comparison using the currently popular Antminer and MSI's RX 470 model 8-card graphics card mining machine as examples.
1. Basic concepts related to mining.
1. What is mining:
Mining is actually accounting through mathematical calculations, and uses a large number of encryption operations to ensure that the ledger will not be tampered with. Mining is the process of producing and issuing cryptocurrency, while using computing power and electricity expenses to ensure that the distributed ledger cannot be tampered with. It can be simply understood as the process of selling the computing power of our machines in exchange for corresponding digital currency returns.
2. What is a mining machine:
The Bitcoin mining machine and graphics card mining machine introduced in this article can be understood as a machine with multiple high-performance CPU chips and graphics cards. computer. Similarly, graphics card mining machines also require basic accessories such as CPU, memory, motherboard, hard drive and power supply.
3. What coins can be mined:
Antminer S9 mining machine mines Bitcoin; graphics card mining machine mines Ethereum (graphics card mining machine can mine Ethereum ETH, Ethereum Classic ETC , ZCash, Monero, etc. Here are only examples of Ethereum.)
2. Calculation of mining income
1. Ant S9 mining machine
/>
It is a Bitcoin mining machine with higher computing power and higher mass production currently on the market, but it is still hard to find. The spot price is 30,000 RMB in the market, and the official price is around 23,000; futures have to be arranged. to April and May.
Hashrate: 13.5TH/s
Power: 1350 watts
Mining machine price: 30000RMB
Electricity fee: 0.5 yuan/degree
The currency price on January 13 is 100,000RMB
The following is the result calculated using the mining website calculator:
Revenue and payback period :
Current daily revenue: 199
Daily electricity cost: 16.2
Daily net profit: 183
Number of days to pay back: 164 days (about 5.5 months)
Summary: The current cost of the Antminer S9 mining machine is 30,000, and the payback period is about 5.5 months. The machine does not have the function of maintaining value.
2. RX470 8-card graphics card mining machine
The same goes for current graphics card mining machines. Many graphics cards suitable for mining are also hard to find. Take the graphics card general agent as an example. In his own words, selling mining machines is not as profitable as mining by himself. He can’t even do it himself. How many mining machines are there, not to mention that the demand in the entire market is so high.
The configuration of the graphics card mining machine, taking the 470 8-card mining machine as an example:
Revenue and payback period:
The total computing power is 224M
Power 1600W
Mining machine price 29000RMB
Electricity fee 0.5 yuan/kilowatt
Price on January 13th 9500RMB
Revenue and payback period:
Current daily revenue: 280.9
Daily electricity bill: 19.2
Daily net Profit: 261.7
Number of days to pay back: 110.8 days (about 3.7 months)
Summary: Based on the cost of 29,000 for an 8-card 470 mining machine and the current currency price, The payback period is probably less than 4 months. And after one year, the graphics card can be sold at a depreciation price of at least 50%.
Actual pictures of the graphics card mining machine:
Summary of the payback period: Antminer S9 is 5.5 months; graphics card mining machine is 3.7 months, and the graphics card mining machine also has depreciation and value preservation .
The above is only based on the comparison of the current currency prices and mining machine prices of Bitcoin and Ethereum. Currently, there are uncertain risks in both buying coins and mining, but relatively speaking, mining The risk is lower than the risk of currency speculation, but the rate of return is relatively stable.
There are still certain risks in mining. The price of mining machines and electricity costs are fixed investments. The currency price is constantly fluctuating. The biggest risk is the drop in currency prices and the increase in computing power. If the currency price halves due to market reasons, or if the computing power gradually increases because more and more players participate, it will lead to a greatly extended personal income expectation or less and less income.
If you can buy a mining machine at a lower cost and mine with lower electricity costs, and recover the cost of the mining machine as soon as possible, you will be sure to make money later. Mining can also be understood as fixed investment. If there are coins that can be mined, they are all hoarding them and waiting for the ideal price to sell them to get a higher return on investment; if someone digs them, they sell them and they will be safe immediately.
It is recommended that everyone invest appropriately within a controllable risk range, try a small amount first, and then gradually increase the number of machines to reasonably control risks. Investments are now considered risk-averse.

For example, on the blockchain mining machine APP platform, users can become miners by registering as members, and miners can earn income through various mining activities, such as purchasing a dedicated mining equipment. You can start mining, and for example: mining when you buy it, mining when you trade, mining when you sign in, mining when you evaluate, mining when you buy a mining machine, mining when you invite people, etc. In other words, any task operation performed by users on the blockchain platform can be regarded as mining behavior.
Every mining behavior of users is contributing value to the platform, and the platform should reward them with coins. The mines mined by users can be circulated in the merchant's own ecosystem. For example, they can be used for financial transactions such as buying and selling on the platform, and can also be used for purchase deductions, cash withdrawals, etc.
⑷ The two giants of blockchain mining machines have successively submitted applications for listing in the United States, desperately trying to catch the "window" to see if they can do so
China Times (chinatimes.net.cn) reporter Yang Liu, Jinhua Wu Reported by Min from Shanghai and Beijing
The trend of the blockchain industry has begun to become clearer as the country issues clear encouragement signals. Canaan and Bitmain, the two major domestic mining giants that have been struggling to go public, seem to have grasped "life-saving straws."
"China Times" reporters learned that on October 28, the U.S. Securities and Exchange Commission announced the IPO documents of chip mining machine manufacturer Canaan Yunzhi. The documents showed that Canaan Yunzhi's plan to raise funds was insufficient. It exceeded US$400 million, which was smaller than the US$1 billion raised during the failed IPO in Hong Kong. This is also the fourth time that Canaan has sought financing channels from overseas capital markets after several unsuccessful IPOs in Hong Kong. .
On the other hand, as the world’s largest cryptocurrency mining machine company, Canaan is also a leader in mining machines and AI cores.Bitmain, a competitor in the film market, is undergoing a "CEO revolt." Just on October 29, Wu Jihan, the co-founder of Bitmain, publicly announced at an all-employee meeting that he would terminate all positions of Bitmain’s legal representative and chairman Ketuan Zhan, who started the business together. The two founders completely broke up. .
On October 30, new news came out of Bitmain. According to reports from self-media in the relevant industry, one week before Wu Jihan launched this "coup" raid, Bitmain had secretly submitted a listing application to the SEC, and the sponsor was Deutsche Bank. This process has been led by Jihan Wu and CFO Liu Luyao, another senior executive of Bitmain, with Ketuan Zhan less involved. In this regard, our reporter also called the relevant departments of Bitmain, but Bitmain declined to comment.
"Both Canaan Ventures and Bitmain have been on the road to IPO in the past two years, but the road ahead is bumpy. Due to the cold winter period in the mining industry, the mining companies of these two institutions have The machine business is deteriorating, and the capital chain is even tighter. Now that the country’s favorable policies have been introduced, there is no doubt that both institutions have begun to rush into the US stock market. Compared with the two capital markets of the mainland and Hong Kong, Canaan has always been cautious about such business, so Canaan It is almost impossible for Yunzhi and Bitmain to be listed in Shanghai and Hong Kong. The US stock market is relatively loose. For Bitmain, Wu Jihan’s strong return means that if it obtains shareholder support, Bitmain will focus on the areas with the most advantages. The blockchain industry is regrouping in the mining machine and mining pool business and launching an impact on the US stock market." On October 30, Liang Ming (pseudonym), an investor in the mining machine business in Shanghai, told a reporter from China Times.
The future of the second "mining company" to go to the United States for IPO is uncertain
Compared with the turbulent Bitmain, Canaan is one step ahead, attacking the IPO for the fourth time and submitting a U.S. stock prospectus .
According to Canaan’s disclosure in the prospectus, the company started by producing Bitcoin mining machines and is the world’s second largest Bitcoin mining machine manufacturer. In the first half of 2019, its mining machine sales were According to calculations, the company's market share in the first half of 2019 was 23.3%, ranking second in the world, and Bitmain's market share was 64.5%, ranking first.
According to public information, as the world's second largest manufacturer of Bitcoin mining machines, Canaan's Avalon mining machine was launched in 2013, which is a commercial ASIC chip Bitcoin mining machine. Bitcoin "miners" bid farewell to the original era of computer CPU and GPU mining and chose high-power ASIC chip mining machines.
In 2015, due to Bitmain’s dominance of the mining industry with its S7 Antminer and subsequent S9 mining machines for many years, Canaan’s new series of mining machines was late in losing its first-mover advantage. In July 2018, Canaan released the Avalon A9 series, which was earlier than Bitmain’s launch of 7nm technology ASIC chip mining machines. Due to the low price of the virtual currency market, Canaan's efforts to make a comeback have had limited success this time.
Reporters found on the official website of Canaan that the Avalon A1166 is currently priced at US$1,978. The A11 series of Avalon A1146, A1066, A1047, A1026 and other mining machines are also on sale.
According to sources in the mining market, Canaan recently released the Avalon A1166, which has a computing power rating of 73TH/s and an energy consumption ratio of 46J/T. A1166 is Canaan's best mining machine at present. Based on the current Bitcoin price and mining profits, the time to pay back the investment is about 230 days.
It is worth noting that in this prospectus, Canaan listed Bitcoin price as the first risk factor. Due to the downturn in currency prices and the sharp fall in mining machine prices, Canaan Yunzhi achieved revenue of 289 million yuan and a net profit loss of 331 million yuan in the first half of this year. Compared with the net profit of 216 million in the first half of 2018, the profit dropped by 252% year-on-year.
“The price of Bitcoin controls the fate of major mining machine manufacturers, and the symbiotic nature is very obvious. Mining machines not only consume electricity, but their mining costs are also affected by the dry and wet periods of hydropower. "On October 28, a mining machine manufacturer in Sichuan said in an interview with a reporter from China Times.
The prospectus shows that the funds raised from this IPO will be used for the research and development of AI algorithms and application-related ASICs, and the company’s future revenue growth will depend on whether it can successfully open up AI. markets and enter new application areas.
In other words, in addition to mining machine sales, Canaan is also working hard in the field of AI algorithms and applications, trying to transform into an AI chip manufacturer.
The mining machine boss also went public after the internal battle
In fact, as the development of China’s blockchain industry has been elevated to a national level, recently in the mining machine industry, especially the two major What happens to the giants is really confusing to the outside world.
Since the "second eldest" Canaan and Zhizhi have chosen to go public, why can't Bitmain, the boss, go public, even though it is currently involved in a battle for management control?
In an important notice issued to employees by Bitmain co-founder Jihan Wu on October 28, he decided to terminate Micree Zhan from all positions in Bitmain, effective immediately. It also stated that any employee of Bitmain shall no longer carry out Micree Zhan’s instructions and shall not participate in meetings convened by Micree Zhan. If there is any violation, the company will consider terminating the labor contract depending on the severity of the case; if it causes damage to the company’s economic interests, the company will pursue civil or criminal prosecution in accordance with the law. responsibility.
There is more news that Wu Jihan subsequently sent another email announcing the dismissal of Wang Zhi, the current head of HR. Wang Zhi was appointed by Ketuan Zhan and seems to be very unpopular within Bitmain. Micree Zhan is currently prohibited from entering the company's office, and employees are prohibited from continuing to follow instructions, which is equivalent to being expelled "out of the country."
"China Times" reporters also sorted outThe development history of Bitmain found that the main operating entity of Bitmain is Beijing Bitmain Technology Co., Ltd. The predecessor of Bitmain was founded by Ketuan Zhan, Wu Jihan was a latecomer, and the circle has always believed that Ketuan Zhan is the real operator of Bitmain. .
In August 2018, Bitmain went to Hong Kong for its IPO. According to the prospectus at the time, Ketuan Zhan held 36% of Bitmain’s shares and was the largest shareholder; Jihan Wu held 25.25% of the shares and was the second largest shareholder. No one has absolute control.
According to analysis by insiders, the root cause of the split between the two parties is the disagreement between the two founders on the company's business line. The core is their different opinions on whether to develop the AI chip business. Wu Jihan prefers to do mining machines and mining, while Zhan Ketuan prefers to do technology and lead Bitmain's AI projects.
Public reports show that in March this year, Wu Jihan had distanced himself from the management of Bitmain.
At that time, Wu Jihan led some core technical personnel to create a new company dedicated to the construction of blockchain infrastructure. Its business included digital currency exchanges, mining pools, etc. It is reported that Bitmain has also invested in Wu Jihan’s new company, while Wu Jihan continues to hold shares in Bitmain. After Wu Jihan "established a new business", Bitmain's business mainly focused on AI chips and mining machine chips, with Zhan Ketuan fully in charge.
However, there are already clues that Wu Jihan can make a comeback this time.
According to information from Qichacha, on October 28, the legal representative of Beijing Bitmain Technology Co., Ltd. was changed from Ketuan Zhan to Jihan Wu, and Wu Jihan also succeeded Ketuan Zhan as executive director. Ketuan Zhan resigned as executive director and continued as manager.
According to a Bitmain insider, in terms of Bitmain’s development direction, except for Kai-fu Lee, most shareholders within the company almost all support continuing to do business related to blockchain, especially mining machines. Business, this is what Wu Jihan has always insisted on. Spurred by previous rivals' submission of prospectuses, shareholders supported Wu Jihan's rise to power, and their primary purpose was to promote Bitmain's listing in the United States.
⑸ Who knows what mining machine to use for blockchain mining?
Blizzard mining machine, high performance, stable system, fast packaging speed, high mining efficiency
⑹ Waiting online, the principle of mining machine mining
Mining machine mining refers to the process in which users use specific hardware equipment (mining machines) to mine digital currencies. The working principle of a mining machine is: it uses specific software and hardware components to complete the mining process, using the processing power of the computer to solve complex mathematical problems in the digital currency network, thereby obtaining digital currency rewards.
The specific process of miner mining is: first, the miner will obtain new transactions from the blockchain network and combine them into a new block; then, the miner will calculate the new block hash value, that is, the block header; then, the miner will check the new areaWhether the hash value of the block meets the requirements of the blockchain network, if so, the miner can add the new block to the blockchain network; the miner will receive a certain digital currency reward.
The principle of mining by mining machines is based on blockchain technology, which is a distributed ledger technology that can record all digital currency transactions and ensure that these transactions are safe and reliable. Blockchain technology is a distributed ledger technology that can record all digital currency transactions and ensure that these transactions are safe and reliable. The core principle of blockchain technology is that a network of mining machines can use computer processing power to complete complex mathematical problems and obtain digital currency rewards.
The advantages of mining with mining machines are: it allows users to obtain digital currency rewards without worrying about security; it allows users to participate in digital currency transactions more conveniently; it allows users to participate in digital currency transactions more quickly; Earn digital currency rewards; it allows users to participate in digital currency transactions more safely.
The disadvantages of mining with mining machines also exist: mining with mining machines requires the purchase of professional hardcore equipment, and the prices of these equipment are relatively high; mining with mining machines requires a large amount of Electricity, and the electricity bill is relatively high; the computing power of mining machines is also limited, and the mining speed is relatively slow; the benefits of mining with mining machines are also limited, because the prices of digital currencies such as Bitcoin are also limited.
In short, mining machine mining is a technology that uses computer processing power to solve complex mathematical problems in the digital currency network to obtain digital currency rewards. It has the advantage of obtaining digital currency rewards. But there are also some disadvantages, such as high hardware purchase costs, large power consumption and limited benefits.
⑺ What is the principle of Bitcoin and blockchain, and what is happening with mining machine mining
Bitcoin is a digital currency generated based on a specific algorithmBitcoin is equivalent to digital gold. As a generally recognized equivalent, gold naturally has monetary properties and has been regarded as a currency in circulation since ancient times. Bitcoin was born in 2009. It was created by a person named Satoshi Nakamoto. As the earliest digital currency, it can be said to be worthless at the beginning of its creation. Until 2017, the highest trading price of Bitcoin exceeded 30,000. RMB and Bitcoin have become a valuable digital currency for the following reasons:
First of all, it is like gold. As a natural mineral, the total amount is limited. The same is true for Bitcoin. According to its own algorithm, it cannot be over-issued, so there will be no rapid devaluation of currency due to excessive currency issuance. Due to algorithm reasons, the number of Bitcoins is controlled to no more than 21 million, and it cannot be issued in large quantities, so its value is guaranteed. .
⑻ Learn about Ethereum mining machines and mining principles in one article
In previous articles, we learned about Bitcoin mining and Ethereum mining respectively. The difference between mines. This article focuses on Ethereum mining and miningmachine part.
Ethereum is an open source public blockchain platform with smart contract functions. It provides a decentralized Ethereum Virtual Machine to process peer-to-peer contracts through its dedicated cryptocurrency ETH. Currently, ETH is mined mainly through graphics card mining machines. The so-called graphics card mining machines are actually similar to home desktop computers, except that each machine has 6-10 graphics cards and no monitor (as shown in the picture).
Picture: Graphics card mining machine
The reason why Ethereum has not developed an ASIC mining machine similar to BTC is mainly due to the special mining mechanism of ETH.
During the ETH mining process, a DAG file will be generated, which needs to be called all the time, so it must have a dedicated storage space. This rigid demand for storage space will lead to the fact that even if ASIC chips are produced, the cost per unit of computing power cannot be significantly reduced. To put it simply, the price/performance ratio is very poor.
Ethereum’s DAG size started from 1GB when the Dagger-Hashimoto algorithm was introduced in June 2016, and has increased at a rate of about 520MB per year to the current 3.7G. It is expected that the DAG size of Ethereum will be at the end of 2020 Will be increased to 4G. By then, graphics cards with less than 4G of video memory will be gradually eliminated.
One thing that needs to be introduced is that since the size of a graphics card mining machine is usually 2-4 times that of a Bitcoin mining machine, the power consumption is only 1/2 or even lower than that of a Bitcoin mining machine. , which makes most people unwilling to build a dedicated graphics card mining machine mine (because the mine mainly earns the difference in electricity charges, and the same area of site can place fewer graphics cards and consume less power). Even if there are a small number of graphics card mining farms, the electricity costs charged are usually higher than those of Bitcoin mining machine farms.
