Mining difficulty of BTC miner

2.

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. In January 2013, Avalon released the 60g / s miner specification and accepted the booking. In January 2013, Avalon delivered the world's first commercial bitcoin ASIC miner, and the core developer of bitcoin network, Jeff
garzik, was fortunate to be the owner of the first commercial ASIC miner.
the most difficult mining problem was 0, and the computing power was about 2p at the beginning of 2013, and now it has reached 100p

5. It's really difficult to mine now. First of all, determine whether your positioning is correct. As mentioned above, you may not be able to play one in eight years in ten years. Of course, you are lucky to dig out a few in one year, but this is gambling. The probability is very small, ha ha

however, you really regard mining as fun and entertainment. If you don't care much about whether you can dig, you can also let your own machine dig all the time. However, the machine configuration above you should not be low, but it is not suitable for mining, just as the swimming champion is not necessarily good at mountain climbing

generally speaking, mining machines mainly focus on graphics cards, which have little to do with processors, main memory boards and hard disks. Of course, they need to be stable and not crash for a long time. In fact, a card is more suitable for mining. In principle, you can go to the network. It is said that before the emergence of R-Series a card, the card with good mining effect was not hd88708750, But we despise the old graphics card that has been eliminated

6. Most businessmen and speculators are always interested in things that can be turned into money immediately. Bitcoin is one of them. The specialization of ASIC chips leads to the market separation between bitcoin mining and other Shanzhai coin mining
when the vast majority of video card mining machines and CPU mining machines are in a mine disaster, bitcoin mining with ASIC mining machines will not be affected. As the first big man in the virtual currency circle, bitcoin has become a deep-rooted belief in the coin circle. The total number of 21 million bitcoins also determines the transaction type and value-added of bitcoin
although bitcoin has begun to be recognized by most people, it has not really replaced the world's currency to fulfill its original intention, but it has become a collection beyond gold. The inflation of money, the rection of the total amount of mining and the increasing difficulty of mining all determine its future market prospects. The value-added has been firmly established, so people will rush to dig for mines, Because the bitcoin is actually worth more than gold

7. The mining speed of the mine with high computing power is fast. If you only consider the calculation power, not the electricity charge, it is estimated that you can easily buy a pile of scrap iron. Of course, if the electricity charge for mining is free, the higher the calculation power, the better the miner will be
the purchase of bitcoin mining machine not only depends on the size of computing power, but also considers the efficiency of some mining machines, as well as the price of mining machines, the increasing difficulty of bitcoin mining and other factors
at present, the mainstream mining machines in the market are Avalon 3 generation mining machine and ant mining machine.

8. 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.

9. If you don't know anything about BTC, I'll tell you nothing about it.
according to the current price and difficulty of mining machinery, none of the mining machinery can recover the cost.
all of them are money losing goods.
