Bitcoin maximum computing power miner
CPU mining → GPU mining → FPGA mining → ASIC mining → large-scale cluster mining
while mining chips are updated, The change of mining speed is:
CPU (20mhash / s) → GPU (400mhash / s) → FPGA (25ghash / s) → ASIC (3.5thash / s) → large scale cluster mining (3.5thash / s * x)
mining speed, which is called computing power in professional terms, is the ability of computer to generate hash collisions per second. In other words, how many hash collisions can our miner do per second is the calculation force. Computing power is the ability to dig bitcoin. The higher the computing power, the more bitcoin you dig, the higher the return
in the world of bitcoin, a data block is recorded about every 10 minutes. All mining computers are trying to package the data block and submit it, and the person who successfully generates the data block will get a bitcoin reward. Initially, bitcoin rewards of 50 bitcoins could be generated about every 10 minutes. But the payment is halved every four years, and now the bitcoin network can generate 25 bitcoins every 10 minutes
in order to successfully generate data blocks, miners need to find the effective hash value. To get the correct hash value, there is no shortcut. They have to guess. The process of guessing is the process of computer random hash collision. If you guess correctly, you will get bitcoin
so far, the highest 1btc price in bitcoin history is about $20000, with a market value of more than $60 billion.
The most advanced bitcoin mining machine, one to two years to dig out a bitcoin, bitcoin mining is now too difficult. If you want to dig, you can dig ether currency. Now it is steadily appreciating every day. According to the current development trend, it will be able to recover its capital in about seven months, and then it will be profitable< br />
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
warm tips:
1. The above explanations are for reference only, without any suggestions
2. Before investing, it is recommended that you first understand the risks existing in the project, and clearly understand the investors, investment institutions, chain activity and other information of the project, rather than blindly investing or mistakenly entering the capital market. Investment is risky, so we should be cautious when entering the market

Xuebao miner A1, miner chip is the core of miner. It is said that bitmine is the source of the whole bitcoin miner instry. Bitmine has its own powerful chip technology as early as the end of 2013. Of course, it also benefits from the joint cooperation and efforts of bitmine and other companies, and Xuebao miner is their own proct. A1 is the world's first customized mining machine, equipped with ASIC chip (bf16btc), the number of chips is as high as 576pcs, the computing power of a single chip is 84.1gh/s, and the overall computing power is as high as 49th / s ± 5%
Z4 adopts Intel al core [email protected] Cup, mining power is 265mh / S (ETH), equipped with independent graphics card 570x8, has 9 fans, and the radiator adopts Intel original radiator, power supply: station flag 2000W power supply, voltage: 12.4-12.6v.

therefore, the mining machine of Hengxun cloud enterprise hard disk is a wise choice. The price of IPFs special mining machine ranges from several thousand yuan to tens of thousands of yuan, and the special mining machine is more efficient than the home computer, saving more electricity.
I won't comment on Zhang Xiaolong's other views, but I have reservations about his view that "wechat wants to build a truly decentralized system and will not provide a centralized traffic entrance to all public platforms and third parties", and that the traffic entrance is in the QR code.
