Miner 2

1.

bitcoin mining machine is a kind of computer used to earn bitcoin. This kind of computer generally has professional mining chips and works in the way of burning graphics card, which consumes a lot of power. It is one of the ways to get bitcoin that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server

mining is actually a competition of performance and equipment, and a competition of computing power among miners. Miners with more computing power are more likely to dig bitcoin. With the increase of computing power in the whole network, it is more and more difficult to dig bits with traditional devices (CPU, GPU). People have developed chips specially used for mining. Chip is the core part of mining machine. The process of chip operation will proce a lot of heat, in order to cool down, bitcoin miner is generally equipped with heat sink and fan

bitcoin is a kind of virtual currency. Bitcoin mining system is the process of carrying out mathematical operation for bitcoin network through computer hardware. Miners who provide services can get a reward, because the network reward is calculated according to the tasks completed by miners, so the competition for mining is very fierce

bitcoin mining started with low-cost hardware such as CPU or GPU, but with the popularity of bitcoin, the mining process has changed greatly. Nowadays, the mining activities are transferred to the field programmable gate array, and the hash speed can be achieved through optimization. The mining efficiency of this mode is very high

2. On today's miners there are many high-quality second-hand mining machine, and there is a warranty problem, there are professional after-sales manufacturers

3.

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

after expansion, an expansion shelf needs to be made. To fix the graphics card and other equipment, we need to get some fans on the shelf to cool the graphics card

CPU is not very important. But not lower than i5< br />

4. At present, the market price of second-hand mining machine is quite different. We need to evaluate the service life and the aging condition of the parts in order to get the result.

5. Few people buy Avalon 2 single-mode group now, and the official does not necessarily have the goods. Now four generations of Avalon have come out. It's very difficult for the fourth generation to recover the cost of mining, not to mention the second generation. If you want to buy the fourth generation mining machine, you'd better buy it. Private letter me, I tell you<

now mining has approached or even exceeded the currency price, and retail Mining has graally withdrawn from the stage of history. However, if your electricity is free, it is still possible and profitable to buy mining machines. If the electricity charge is free, we suggest you buy the fourth generation miner or ant S5

6. There doesn't seem to be any big units over there. They sell motorcycles, doors and windows, and there's a big base for planting flowers. There's a community over there

7. The most important thing is to ensure the safety of funds, do not pay the seller, the other side does not give you delivery, followed by the selection of reliable sellers, this line of water is too large, many of the mining machine are indivials, really run can not find, you can go to today's miner official website to understand, or publish the machine you need.

8. There is no doubt that it can be surpassed. Although tianhe-2 has super computing power, it is not specially used for bitcoin mining. Bitcoin ASIC miner is specially designed for bitcoin algorithm, with strong computing power. Some netizens calculated a sum of money, and converted the computing power of tianhe-2 into mining efficiency. About two to three bitcoins can be g out in an hour, which is 15000 yuan. That's 360000 yuan a day. Mayor Chen Jianhua said that tianhe-2's daily electricity bill is 300000 yuan, which seems to make a little money. However, if labor costs, depreciation of machinery and other costs are taken into account, "mining" will not make much money. This is the result of last year's calculation. According to the current difficulty of mining, the profit is much less than this

at present, bitcoin mining is a very professional business, which has graally developed into an intensive large mine. The upgrading of bitcoin miner is very fast. Take Avalon miner, the mainstream miner in the market, as an example. At present, three generations of chips have been upgraded, and the fourth generation is expected to come out soon. In the future, it can be predicted that mining will graally move towards concentration, retail investors will graally disappear, and mining will have a large-scale effect.

9. Avalon mining machine consumes a lot of electricity. It's difficult to earn back the electricity bill and it's noisy. Guangtian mining machine reminds you to understand these before you buy it. Ants are more cost-effective, quiet and low consumption. If they are bigger, they choose the 1t miner of Ajie of longkuang.
