How many computers can dig a bitcoin
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
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
1. The calculation is mainly done by GPU, while the GPU of ordinary computers is not very powerful, which directly leads to the low efficiency of mining, and even the electricity bill can not be recovered
2. Because it is the exchange of data on the network, not only the performance of the computer should be good enough, but also the bandwidth and quality of the network should be higher. If you were asked to build a 100 megabit broadband of Telecom before, would you be so interested
3. GPU will generate a lot of heat ring calculation. If it is not handled properly or the original radiator is very dirty, it may burn the GPU or computer, and the gain will not be worth the loss
4. The other is the impact of the environment. Let's not say where bitcoin is going, but that the exchange rate is seriously declining and there is no money to be made before. Professional mines are even processing equipment. It's obviously unreasonable to go mining at this time.
bitcoin mining refers to the creation and addition of bitcoin blockchain in the process of block transaction. Each block contains hundreds of transactions, and each transaction is paid from one or more bitcoin addresses, other addresses or addresses
the process of creating blocks is called bitcoin mining because there are rewards for each new block to be created and added to the blockchain. In 2017, the reward was 12.5 bitcoin. So as long as you are faster than others and create a new block, you can get a 12.5 bitcoin reward
obviously, the speed of mining depends on the running speed and stability of the computer. Therefore, only professional "mining machine" can be competent for this job. This kind of machine configuration is very high, power consumption is very large, often need more than one cooperation.

After surpassing the peak in 2017 and breaking the $20000 mark, bitcoin has not stopped soaring. Bitstamp market shows that bitcoin has broken through the $34000 mark, a new record high
you know, as early as 2010, a programmer in the United States exchanged 10000 bitcoins for a $25 pizza. Now, a bitcoin has risen to a high price of 220000 yuan
Therefore, the author suggests that ordinary people who want to take the opportunity to invest should not invest too much. After all, bitcoin's sharp rise and fall is normal, so the investment risk is high, so we need to be cautious when entering the market
