How long does BTC mining machine take out

5.

Recently, the price of bitcoin continued to rise, reaching a maximum of US $41000. According to Mr. Liu, the manager of the mine, recently some customers have asked for additional orders, but the output of the mining machinery manufacturers is insufficient and they can't get a large number of mining machinery. Now they have to wait five months or more. Most of his customers have increased their positions in the middle of this year. At present, the prices of mainstream mining machines vary from 30000 to 60000, Mining takes about 12 months to recover the cost

therefore, if people really have mining ideas, they should not be dazzled by the impulse of the moment, and they should try to do it slowly. Today, the price of bitcoin continues to rise, largely because many mainstream investment institutions or investors begin to be interested in digital assets and begin to hoard bitcoin

bitcoin investment has great risks, the phenomenon of sharp rise and fall is not uncommon, and there are not a few people who have lost all their money. Therefore, it is not advisable to follow blindly and keep calm in investment

6. First of all, you need to understand the time point of bitcoin Mining:
a total of 2100W bitcoins are issued, and each block is generated for 10 minutes, and a block rewards a certain number of bitcoins. In the beginning, 50 bitcoins were awarded for each block of mining. In the future, the reward was halved for every 21000 blocks (about once every four years). Now, 12.5 bitcoins are awarded for each block generated. The generation time of each block is 10 minutes, but with the development of computer technology, now the mining calculation power is increasing, so the generation time of a block must be less than 10 minutes, which requires certain control measures to ensure this time. This measure is the difficulty of mining. If the output time of each block is less than 10 minutes, the difficulty of mining will be increased. If the output time is more than 10 minutes, the difficulty of mining will be reced. The difficulty adjustment time is 2016 blocks, that is, 2 weeks
after every 2016 blocks, all nodes will automatically adjust the mining difficulty according to a certain formula. This formula is obtained by comparing the latest time spent in 2016 blocks in this cycle with the expected time (20160 minutes, i.e. two weeks)
new difficulty = old difficulty * (time spent in the past 2016 blocks / 20160 minutes)

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.
