How much BTC can we dig in 1st

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.

At present, bitcoin needs to be g by professional mining machines. 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

according to the current speed and the number of bitcoins, it will take three months to get a bitcoin if a computer is kept in a 24-hour state of operation

extended data:

because the current bitcoin mines use special bitcoin mining machines to mine. The computing power of an ant S9 miner is 13.5th/s, which is equivalent to the sum of the computing power of 7500 1080ti graphics cards. A medium-sized mine has hundreds of such miners

the instry of bitcoin is not very good either, so you'd better not dream of becoming rich overnight with bitcoin. Now many countries have issued policies to suppress the rise of bitcoin prices. Some countries even refuse to dig bitcoin. Many bankers and economists are disgusted with the emergence of bitcoin

4. This is definitely a loss.
recently, I saw a test that the rtx3070 notebook only earns 1.2 yuan an hour.
1050ti computing power is less than 1 / 4 of 3070, which is about 24%
power consumption is 35% of 3070.
energy consumption is not cost-effective. One hour's income is definitely less than 1 yuan, except for the electricity charge. Once the loss of notebook is eliminated, it is definitely a loss

Austria, Belgium, Denmark, Germany, Greece, Spain, France, Ireland, Italy, Luxembourg, Netherlands, Portugal, Finland, Sweden, United Kingdom, Estonia, Latvian, Lithuanian, polish, Czech, Slovak, Hungarian, Slovenian, Maltese, Cyprus); Add the EFTA member states (Iceland, Lichtenstein, Norway); It also includes countries that are preparing to join the EU (Turkey, etc.). How to get CE certification? The following is a series of steps to obtain CE certification. Considering the difference of procts and their dangerous characteristics, several corresponding steps should be paid attention to. First, find out if there are any instructions applicable to your proct. If there is more than one such directive, your proct must comply with one of them. Determine to what extent your proct design and proction must meet the main requirements of the required instructions. Choose a unified assessment process based on the options provided in the instruction. Usually you have to fill in a & quot; Unified evaluation process & quot; Table, which asks you to provide proct characteristics in the form of a series of questions in order to classify its hazard level; At the same time, it includes many options to require manufacturers to confirm their procts and affix CE certification. The unified assessment process table requires that procts with low risk should be provided with a unified statement of self-test and attached with CE certification; The procts with high risk can apply for testing, supervision or other certification from the announcement agency. Choose applicable proct standards and testing methods for procts. If the proct needs to be tested separately, an independent laboratory shall be selected for testing. Set up an authorized representative for your procts in EU countries. Some directives require the manufacturer to appoint a representative in Europe to provide technical documents in time when the customer needs them. These instructions require manufacturers to prepare technical documents. In this way, customers can learn from the documents that the target proct has passed the test and meets the required standards. Prepare a unified declaration, including a package of instructions and standards your procts comply with, proct certification, manufacturer name, address and signature. CE certification itself does not provide details of the proct to the authority. The information in the uniform declaration must be detailed. According to this table, the manufacturer or its authorized representative in the EU can be found. Pasting of CE certification mark. The paste of CE certification mark must be in accordance with the regulations. The regulations indicate the size and pasting position of CE certification mark; Attach the logo to the proct, packaging, materials or documents shipped with the proct; There are restrictions on when and who can paste the CE mark. Who will carry out CE certification? According to the general proct safety directive (92 / 95 / EC), each member state of the EU can use laws, regulations and administrative regulations to ensure the safety and reliability of procts put on the market. As for specific implementation, each country has its own set of methods. Many countries set up special personnel to carry out on-site inspection of the instructions, and accept and handle consumer complaints. In other countries, the return of goods to the place of origin and economic punishment are combined. However, most countries adopt the mechanism of monitoring and training procers and distributors rather than resorting to legal action. Generally, such training is provided by the customer to the manufacturer. EU law stipulates that importers are responsible for the safety of their imported procts, including the machines provided by importers to employees for proction.

6. In 2020, with the rapid development of blockchain, many applications will be implemented one after another. Only ant financial services has more than 40 application scenarios in blockchain technology, covering commodity traceability, public welfare traceability, cross-border remittance, supply chain finance and electronic bills. With the continuous breakthrough of blockchain application scenarios, bills in the fields of supply chain finance, cross city travel and public welfare fund-raising also usher in the era of comprehensive blockchain. Blockchain technology can solve the problem of trust. Blockchain electronic bills are replacing paper invoices, and blockchain electronic bills are spreading across the country. Cipher finance mimacaijing, focusing on blockchain information.
