Mobile phone Ethereum mining machine

1.

Miner components include CPU, GPU, motherboard and hard disk, similar to a high configuration computer with a hard disk. Self assembly mainly depends on which aspect of hardware performance you want to highlight

mining machine has computing power, display card mining machine and storage mining machine. Daotong storage has long been concerned about the dynamic and hardware supply of mining machine, and its own components will be cheaper than those of the manufacturer< br />

2. I don't know if you use it in a mine or try water. If you're afraid of trouble, it's a brand-name machine to save trouble. You can plug in the power and connect the network cable when you buy it. It's like the one in the galaxy miner, which is more suitable for Xiao mining

3. Buy mining machine is best to go to the official website, there is a guarantee, Galaxy mining machine is good

bitcoin uses SHA-256 encryption algorithm. When mining, it competes with computing power. In order to improve computing power, bitcoin has gone through four stages: CPU mining, GPU mining, FPGA mining and now ASIC mining machine mining, and the degree of specialization is getting higher and higher

Ethereum uses the ethash encryption algorithm. In the process of mining, it needs to read the memory and store the DAG file. Because the bandwidth of each read memory is limited, and the existing computer technology is difficult to have a qualitative breakthrough in this problem, so no matter how to improve the computing efficiency of the computer, the memory read efficiency will not be greatly improved. Therefore, in a sense, Ethereum's ethash encryption algorithm is ASIC resistant.

different encryption algorithms lead to great differences in mining equipment and computing power between bitcoin and Ethereum

at present, bitcoin mining equipment is mainly ASIC mining machine with a very high degree of specialization. The maximum computing power of a single mining machine is 110t / s, and the scale of computing power of the whole network is more than 120eh / s

the main mining equipment of Ethereum is video card miner, and there are very few specialized ASIC miner. On the one hand, the "ASIC resistance" of Ethereum mining algorithm improves the threshold of developing ASIC miner. On the other hand, after Ethereum is upgraded to 2.0, the consensus mechanism will be transformed into POS, and the miner can not continue mining

compared with the ASIC miner, the graphics card miner has two orders of magnitude difference in computing power. At present, the computing power of mainstream graphics card miner (8 cards) is about 420mh / s, and that of Ethereum is about 230th / s.

from the time dimension of the past two years, bitcoin's computing power of the whole network is growing rapidly, while Ethereum's computing power of the whole network is growing relatively slowly

The ASIC mining machine of

bitcoin is monopolized by several major mining machine manufacturers, and miners can only buy it from the market; Although the graphics card miner of Ethereum is also manufactured by a special miner, the miner can buy accessories from the market and assemble them according to his own demand

5. At present, most of the mainstream Ethereum mining machines in the market come from bitmainland and Jianan Yun. However, with the decline of Ethereum's price, the profits brought by mining have been very meager. Investors can choose to invest in Ethereum on the digital currency exchange. At present, the mainstream digital currency transactions in the market are all coin security, fire coin network, bitnet, etc.

6. The core component is the graphics card, which accounts for about 80% of the cost, followed by the motherboard and power supply, with high configuration. If you're digging deep in the mountains with a large mining machine. If personal computers are not enough for electricity, you can also choose crowdfunding mining machine... And now mining is generally in the place where electricity is cheaper, and the money is usually directly linked to the platform (currency exchange trading platform). Personal suggestions should be considered. After all, electricity is not enough.

7. I'm sure I can't get a ticket to buy a new one these days. Buy second-hand, don't try to be cheap. They're all paid for. If you can buy a good second-hand, then the money will be fast. Want to buy a good second-hand excavator, Shanghai Jincheng second-hand market

8. Hello, I'm an old user of Feixun. It's easy for me to buy it at 0 yuan. It's simple, that is, they will return you the full amount of cash after purchase. This purchase mode has been carried out by fisun for several years, and it has never been overturned. I bought their router and air purifier, and this time I bought two C8. How to say, investment is bound to have risks, but we should be good at judging the trend. Everything will fall when it reaches the peak, and rise when it reaches the lowest point. Now it's in a bear market, it won't go up or down, but I personally think it will go up in the future. At present, Ethereum's blockchain technology is up-to-date and Turing is complete. Many experts predict that within 2-3 years, Killer Software Based on Ethereum's blockchain technology will appear. This is my personal point of view, which needs the subject's own judgment.

9. This requires you to calculate when the cost of expenses can be recovered. However, at present, most mining machines can not be returned (in bitcoin), not in legal currency.
