1. 
at present, the computing power of bitcoin in the whole network has reached 2.36 billion hash collisions per second, which is equivalent to the number of water droplets in more than 200000 50 meter long standard swimming pools. But even with such a large amount of computing power, it will take about 10 minutes to hit a hash value that meets the requirements
in 2012, bitcoin's output was halved for the first time, and in July 2016, bitcoin's output was halved for the second time. At present, 12.5 bitcoins are awarded for recording one page of account book. The next halving will take place around 2020, and the total number of bitcoins will not increase by 2040, with a total of 21 million. In other words, the difficulty of digging bitcoin is increasing, while the time required is increasing
2. 21.5 * 3600 seconds * 24 hours = 1857600 M / day
1857600 / 1024 / 1024 = 1.7715 T / day
a t of computing power / day can dig bitcoin worth 4.03 yuan
1.7715 * 4.03 = 7.14 yuan / day
since 2017, bitcoin has reached new heights. Yesterday (May 23), the value of bitcoin broke through the ￥ 16000 mark, hyping virtual currency, becoming a matter that the general public can participate in, And a little bit of technical level, both fried money, but also began to have the technical content of mining
as we all know, virtual currency has a numerical peak, the more difficult it is to dig. In fact, it's hard to judge whether to lose money or not if we continue to dig. Therefore, in the end how to dig, dig what can be the fastest back to this, this paper studies the above two core issues based on the current market situation
3. 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. More than 30000 bitcoins, one 470 second-hand, more than 300 and six 1800. It should take at least 20 years to calculate the annual income of 100%. Besides, the graphics card is not suitable for bitcoin.
5. 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. According to the current calculation, it will take at least 650 days to dig out one under the top configuration< It's estimated that rx588 will cost 1000 days.
7. Introce the reward mechanism of bitcoin system. Bitcoin can basically dig out a block every 10 minutes through system settings. The reward for each block is given to the miners who dig out the block. The miner who digs out the block is called the block miner. The block miner will record the legal transactions in the bitcoin network to the blockchain, so that the miner can receive the service charge for bookkeeping
8. As I told you just now, there's no way to guarantee how long the mine card will last. After all, the manufacturers don't guarantee the service life of the graphics card. If you're lucky for one year or so, it's only three or five months if you're not. After all, the mine card works under high intensity,
