1. From cheap electricity to centralized mining, China's resources and environment provide bitcoin miners with many advantages. In recent years, bitcoin miners have used cheap electricity to expand their business in coal rich regions such as Xinjiang and Inner Mongolia, which are home to the founders of some of the world's leading mining companies

with the rising price of bitcoin, more and more people join the bitcoin mining business. Accordingly, mining consumes more and more energy. Obviously, our government is also aware of this

according to the requirements of the document, regulators require local governments to take measures related to electricity price, land use, tax and environmental protection to guide bitcoin miners to withdraw from the business. According to foreign media reports, regulatory authorities are mainly concerned about the money laundering and financial risks involved in the shutdown policy, but excessive power consumption is also a factor that can not be ignored. In principle, bitcoin mining consumes a lot of power because every time a new bitcoin is proced, it needs to solve the complex mathematical problems through the encryption process performed by a high-performance computer. Mining calculation process is used to verify bitcoin transactions in the blockchain to ensure security, but the disadvantage is that it consumes a lot of energy.
2. Firstly, the cost of bitcoin mining can be divided into three parts:
1. Machine cost: the cost of purchasing mining machine
2. Power cost: the power cost consumed by machine mining
3. Auxiliary costs: personnel maintenance, network, cable consumables, heat dissipation, etc.
for a simple example, take the mining machine of ant S9, which consumes less power on the market, for example, the calculation power is 13.5T, and the power consumption is 1400W
when the mining machine runs for 24 hours: 1.4kw * 24 = 33.6 degrees
Shenma m3, which consumes more power on the market, has a calculation power of 11.5t, The power consumption is 2150w
under 24-hour operation, the power consumption of a single machine is 2.15kw * 24 = 51.6oc
which is roughly equivalent to the power consumption of energy-saving air conditioning, but the bitcoin miner needs 24-hour uninterrupted operation, the power consumption of a single machine is very large after a year's calculation, and the step price cost of household electricity is too high, When the market is not good, the income may not be enough for the electricity expenditure, so at present, mining will choose to be hosted in the mine, which can get cheap electricity and rece the cost price of mining. The price below 30% is the ideal price, which can keep the price of bitcoin falling to a low level, and there is still some income< According to the current mining difficulty of bitcoin:
BTC revenue per ton: 1th / s * 24h = 0.00007087btc
calculated by the comprehensive 12t machine computing power, the daily output is:
0.00007087t * 12t = 0.00085044btc
then the time required for a single machine to dig a BTC:
1 / 0.00085044 = 1175 days
the time required for ten mining machines to dig a BTC:
1 / 0.0085044 = 117 days
100 days In other words, according to the current difficulty, it takes about three years for a single miner to proce a bitcoin, 3.9 months for ten miners to dig a bitcoin, and 11.7 days for a hundred miners to dig a bitcoin. The cost of a single miner is about 8500, Ten are around 85000, one hundred is 850000, less than one million, and one month's income is more than two bitcoins. According to the current price of bitcoin, the price is about 120000. So, although the income of bitcoin mining is not as good as before, it is still considerable compared with other investment projects
however, these benefits do not include decting the cost of electricity charges and later maintenance of machines, so the premise of mining is to find a mine with low electricity charges. If the quantity is large, we need to find a safe, reliable and stable mine. What's more, we need cheap electricity to lower the cost price.
3.

You can't dig in a day. It takes 2000 years

the global unified computing difficulty of bitcoin is 2621404453 (expected to change in two days). It takes more than 2000 years for a 2.5GHz CPU to work out a bitcoin

in order to make the graphics card fully loaded for a long time, the power consumption will be quite high, and the electricity bill will be higher and higher. Many professional mines at home and abroad are operated in areas with extremely low electricity charges, such as hydropower stations, while more users can only mine at home or in ordinary mines, so the electricity charges are not cheap. Even in a certain residential area in Yunnan, there was a case of crazy mining, which led to a large area trip of the residential area, and the transformer was burned


extended data:

bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system

bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network can get a qualified answer about every 10 minutes. Then bitcoin network will generate a certain amount of bitcoin as block reward to reward the person who gets the answer

when bitcoin was born in 2009, block rewards were 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the block reward will be halved to 25

when the total amount reaches 15.75 million (5.25 million new output, i.e. 50% of 1050), the block reward will be further halved to 12.5. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to about 21 million

4. Now it's not very profitable. In 12 years, the price of bitcoin was about 1000 +. With personal PC, we could dig more than one coin a week. The current currency price is about 20000 yuan
Development:
1. Bitcoin (bitcoin) is a kind of network virtual currency, which can buy real-life goods. It is characterized by decentralization, anonymity, and can only be used in the digital world. It does not belong to any country or financial institution, and is not subject to geographical restrictions. It can be exchanged anywhere in the world. Therefore, it is used as a money laundering tool by some criminals. In 2013, the U.S. government recognized the legal status of bitcoin, making the price of bitcoin soar. In China, on November 19, 2013, a bitcoin was equivalent to 6989 yuan
2. On January 7, 2014, Taobao announced that it would ban the sale of Internet virtual currencies such as bitcoin and lightcoin from January 14. West Virginia Democratic Senator Joe; On February 26, 2014, Joe Manchin issued an open letter to a number of regulatory authorities of the US federal government, hoping that relevant institutions would pay attention to the current situation of bitcoin encouraging illegal activities and disrupting the financial order, and demanded that actions be taken as soon as possible to completely ban the electronic currency. On January 11, 2017), the Shanghai headquarters of the people's Bank of China and the Shanghai Municipal Finance Office carried out on-site inspection of bitcoin China.
5. This income is not fixed. Today is July 17th. According to the difficulty of today, you can dig 0.019 BTC a day. Today's price of okcoin exchange is 578, so your daily RMB income is 10.982 RMB. The difficulty will increase day by day, and your income will graally decrease!
6. Different from bitcoin mining, IPFs mining does not require high electricity charges, but has certain requirements for network bandwidth and stability. Therefore, if IPFs mining machine wants to give full play to its functions, it also needs supporting "mines" and large-scale cluster mining. You can go to Renren mine website to learn about IPFs mining.
7. For example, when I buy a miner with 20000 tons of computing power, the cost is 1000 tons. The one who sells cloud computing power is to buy a machine with 2000W, 20 tons of computing power, 1000 tons of computing power. He sells 13001500 tons of computing power. In short, cloud computing power is not reliable. The one who sells cloud computing power is to earn the price difference of mining. It's better to buy a miner to dig
8. In order to know what mining is calculating, we must first know the essence of bitcoin and its proction process. Bitcoin is a network-based electronic currency, which is actually a string of codes of the Internet, calculated by algorithms. Mining is the process of completing the algorithm and the only way to proce bitcoin. And because of the algorithm, there are only 21 million bitcoins
1. Mining can not only proce bitcoin, but also guarantee transaction information
similarly, a mathematical system contains 21 million mathematical problems, so we need to constantly seek the special solution of each mathematical problem through a huge amount of calculation. In addition, the special solution is unique
mining can not only increase the supply of bitcoin money, but also protect the security of bitcoin transactions and prevent fraulent transactions. In terms of process, bitcoin network is a point-to-point payment system, and anyone can trade through the transaction program
in order to ensure that the transaction process is truthfully recorded, the role of "miner" is required to be responsible for recording bitcoin transaction information. The time interval is 10 minutes. The best recorded transaction records among miners will be packaged and stored in a new block, and the corresponding miners will also receive a certain amount of bitcoin rewards
2. The mining process is extremely complex, which is beyond human power
the specific process is as follows. When a miner listens to the transaction, he will first verify the transaction information. The verified transactions will be recorded by miners and stored in their own database. There may be thousands of miners in the world doing the same thing, but every ten minutes, only one miner has the right to create a new block, so that the transaction information recorded by himself can be recognized and stored permanently
next, miners need to fight for the right to keep accounts. This is a competition of computing power. The core of this competition is to use computers to complete a large number of calculation tasks and find a super difficult random number. This random number is the special solution of the equation mentioned in the first paragraph. The miner who calculates the correct random number first wins. According to the rules of the game, the probability of a miner getting the accounting right is directly proportional to the proportion of his computing power in the total computing power of the whole network. In other words, the probability of finding the random number is equivalent to throwing out 100 million dice, and the total number of dice is less than 150 million. Therefore, mining requires a large number of computers, installation of specific algorithm software, repeated operation day and night, not human
3. Bitcoin mining is actually "villagers' bookkeeping"
maybe some netizens still don't understand, let's take an example. In a village, the villagers often borrow money from each other, even if they write a written document, there is a risk of default. Then, every time there is a loan behavior in the village, we will use the village trumpet to inform everyone that all the villagers (miners) will record all the transaction records in their own account books.
9. < blockquote >

mining of bitcoin in Inner Mongolia is restricted, and the computing power of mining of bitcoin in Inner Mongolia is greater than that of the whole United States, because the electricity price in Inner Mongolia is cheap and the computing power of data center is abundant

economist Peter middot; Schiff once predicted that the future of bitcoin is full of uncertainty, and there is still no endorsement such as sovereignty or margin. If the capital withdraws, bitcoin will be worthless. China's policy of not proposing mining will also help guide investors to avoid the Ponzi scheme

10. It's hard to say. If the currency price continues to fall, the miners generally lose confidence in bitcoin, and the mining income is seriously lower than the mining cost, then a large number of miners will stop mining, and the computing power will drop sharply. In addition, because the major countries in the world adopt a more stringent attitude towards bitcoin, such as China and the United States, bitcoin's computing power may also drop sharply, or even disappear

but bitcoin mining as an infrastructure, if bitcoin can continue to exist, although the income of mining is reced, for the security of the whole bitcoin network system, some big bitcoin companies may invest in mining to maintain the security of bitcoin network system. In addition, the future of bitcoin will become more clear and bright. Bitcoin's computing power will not decrease, but will increase.
