Bitcoin mining machine S4

Only those whose electricity charges are controlled within 0.3 yuan can mine. At present, the daily income of a bitcoin S9 is about 55 yuan (calculated at 7000 yuan), so 30 is 30 × 55 = about 1650 yuan (210000 yuan)

bitcoin is a kind of universal encrypted electronic currency in the world, and it is completely autonomous by users. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system

the concept of bitcoin was first proposed by Nakamoto in 2009. Unlike most currencies, bitcoin does not rely on specific currency institutions to issue. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of money circulation. 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 21 million

bitcoin can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual goods, and they can also use bitcoin to buy real-life goods. On December 11, 2017, bitcoin futures began trading on the Chicago Board of Options Exchange (CBOE). On January 24, 2018, the Bank of Indonesia announced the ban on bitcoin payment

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

Mining needs high-end graphics card, mining equipment is the first to eliminate NV graphics card. Mining must be done with graphics cards. The overall structure of mining equipment and ordinary PC machine is different is the number of graphics cards. You can install four or eight through pic extension
