2. 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
3. According to the current total
computing power and the current growth rate of total computing power, it will take about 250 days to dig a bitcoin
4. Cloud
mining mode. Mining machines are troublesome. They have to be assembled by themselves and then put into the mine, and the electricity and maintenance costs are also amazing, which is a large amount every month. Cloud mining is to have people to help you put the mining machine in custody in the mine, you don't have to do it yourself.
5. Bitcoin mining is to use the computing power of your mining equipment to calculate mathematical problems and confirm transactions. The system will give unequal bitcoin rewards according to the amount of computing power you contribute to the whole network. Bitcoin mining has gone through three stages. In the first stage, we use CPU to mine, because there are few people mining; The second stage, we use the graphics card mining, popular point is burning graphics card mining, players began to wake up; In the third stage, professional ASIC mining machines are used for mining. Starting from Avalon's mining machines and the introction of cat roasting mining machines into the market, the computing power in this stage is surging, and the mining difficulty is increasing. In the following period, new mining machine manufacturers continue to join the mining machine instry. However, with the increase of computing power and the progress of technology, Some mining machinery manufacturers began to go bankrupt or fade out of the market. Avalon has always been active in people's field of vision and constantly launched new chips. At present, Avalon has launched three generations of mining machinery chips, and the fourth generation will soon be launched.
6. Don't bother. They can't compete with professional miners,
