Why is it not suitable for bitcoin mining at this stage
but what I want to emphasize is that bitcoin mining is now a very professional instry. Although ordinary people can dig, the cost is much higher than that of professional mining, so it's better to buy money directly.
as tens of thousands of miners compete for the right to pack, the probability of a single miner seizing the right to pack is very small, and the output is very unstable. It is possible to grab the right once an hour or not once a year
in order to stabilize the mining output, miners often choose to join the mining pool. The mining pool integrates the computing power of a large number of miners and occupies a certain share in the total computing power of the whole network, so as to obtain a more stable mining output. After charging 2% ~ 4% of the pool handling charge, the output is distributed to the miners according to the miners' computing power
it's just like that it's hard for one person to win the lottery, so the mine pool organizes many people to buy the lottery together, and after winning the lottery, they are distributed to everyone according to the amount of contribution.
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.
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
mining is a process of consuming computing resources to process transactions, ensuring network security and keeping everyone's information synchronized in the network. It can be understood as the data center of bitcoin. The difference lies in its completely decentralized design. Miners operate all over the world, and no one can control the network. This process is called "mining" because it is similar to gold panning, because it is also a temporary mechanism for issuing new bitcoin. However, unlike gold panning, bitcoin mining provides rewards for services that ensure the safe operation of payment networks. After the last bitcoin, mining is still necessary.
first of all, mining is the main way to obtain bitcoin, but the current threshold of mining is relatively high. If you choose to mine by yourself, first you need to understand certain technology, then download the bitcoin client and mine by yourself according to the online bitcoin mining tutorial
however, in theory, bitcoin can still be mined with computers or graphics cards. However, e to the development of mining instry in recent years, the whole network computing power of bitcoin is extremely terrible (more than supercomputers), so if you want to mine with computers or graphics cards, you can't find bitcoin, If you want to dig bitcoin, you still need to buy mining machines. Now the better mainstream mining machines in the market have to be tens of thousands. Of course, there are cheap second-hand mining machines, but these second-hand mining machines are all obsolete ones, and the electricity cost of mining is relatively high
in addition to the second way of direct purchase, the digital currency exchange is a special place for bitcoin trading. If you want to own a bitcoin, you can buy it directly with money. However, it should be noted that there are many digital currency exchanges in the market at present. Many small exchanges are specialized in cutting users and eating customer losses for a living. Therefore, when choosing an exchange, it is better to focus on the head exchange. For example, Hufu, one of the head exchanges in China, I have been using it for nearly two years, and it is very stable and safe.
According to the exchange rate on January 6, 2020, 1 pound = 9.1143 yuan, 1 yuan = 0.1097 pound, 500 pound = 4557.15 yuan sterling was issued by the Bank of England, which was founded in 1694. The unit of secondary currency was shilling and pence. One pound was 20 shillings and one shilling was 12 pence. On February 15, 1971, the Bank of England implemented a new currency carry system. The unit of secondary currency was changed to new pence and one pound was 100 new pence the banknotes in circulation include 5, 10, 20 and 50 denominations of pounds, 1, 2, 5, 10, 20 and 50 new pence and 1 and 2 coins extended data: Britain formally adopted the gold standard system in 1821, and the pound became the standard monetary unit of the United Kingdom, containing 7.32238 grams of pure gold per pound. When the first World War broke out in 1914, Britain abolished the gold standard, stopped the circulation of gold coins, and stopped exchanging gold
The answer is: there are several goals, one withdrawal and one withdrawal. It's hard. Good luck
the popular point is to use the computing power of your computer to solve mathematical problems, and then give you a certain amount of bitcoin in return
bitcoin mining has gone through three stages, CPU, GPU and ASIC
. At present, bitcoin mining needs professional ASIC mining machine. At present, Avalon and butterfly laboratory are more famous mining machinery manufacturers in the market, but American butterfly laboratory likes to evade tickets. Avalon has proced the world's first ASIC miner. At present, Avalon's third generation chips have been put into the market, and avalon3 miner is about to enter the market.
