Why Bitcoin Mining Needs ASICsminer?
When Satoshi Nakamoto designed Bitcoin, he hoped that people would use their home computers to mine and use the computing power of the CPU to collide with the hash value to obtain Bitcoin. Later, people discovered that Bitcoin mining is only for SHA256 calculations, and functions such as CPU floating-point calculations are completely useless. Large-scale mining is not cost-effective from a cost perspective.
The graphics card cuts off a lot of useless computing functions for the sake of image processing capabilities, which is just similar to the calculation method required by Bitcoin. But even so, graphics cards still have a lot of idle computing power during mining, so ASIC mining machines came into being.
An ASIC mining machine is a computer that specializes in executing mining programs, and can do nothing but mining.After sacrificing general-purpose computing power, the mining capacity and efficiency of ASIC are also greatly improved.
For example, the current mainstream Antminer S9 uses 189 pieces of ASIC chips, with a computing power of 13.5TH/s, the price of the whole machine is only 14,000 yuan, and the power consumption is 1350W. As a comparison, the current computer flagship graphics card NVIDIA GTX1080Ti single card costs 6,000 yuan and consumes more than 300W of power, but the mining computing power will basically not exceed 60MH/s, which is hundreds of thousands of times different from the computing power of the ant mining machine S9.

We need to understand the following concepts before buying Bitcoin ASIC mining machines:
computing power. The computing power of a bitcoin mining machine represents the rate at which bitcoins are acquired. For example, the current computing power of the entire network is 32.54EH/s, and 1900 bitcoins are produced in 24 hours. Then a mining machine with a computing power of 4T theoretically produces about 0.0002 bitcoins per day, which is about 10 yuan.
power. Power represents the power consumption rate of a Bitcoin mining machine. A 1000W mining machine consumes 24 degrees of electricity in 24 hours.
cost. In terms of electricity consumption, the average household power supply is about 0.5 yuan/1 kilowatt-hour. A mining machine that consumes 24 degrees of electricity per day has an electricity cost of 12 yuan. In terms of network, the mining machine does not have high requirements on the network. 1M bandwidth can carry 150 mining machines, and the cost is almost negligible.
Payback cycle (theory). Payback period = (daily income - electricity fee) / mining machine price, the payback period is only a theoretical calculation of the number of days, the bitcoin market is changing every day, and the difficulty of computing power is also increasing, plus mining pool and transaction commissions , so it is difficult to calculate the exact payback cycle time.
When we plan to buy a Bitcoin mining machine, the most important thing we should pay attention to is the price per T of computing power and the ratio of computing power to power consumption.Precautions:
Precautions:
Do not buy mining machine products with high computing power. At present, there is not much difference in ASIC chip technology. Excessive computing power means that there are too many ASIC chips in a single mining machine, and the internal structure of the mining machine is too complicated, which is not convenient for maintenance.
Don't over-idealize the return cycle. Power failures, network failures, and mining machine failures during operation will all affect the final income.
