Home bitcoin devices

1.

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 />

2.

First of all, if the home computer is used to calculate bitcoin, even if the configuration is high, it will take several days to dozens of days. It may come out with a string of effective bitcoin (that is, bitcoin), and then it can be traded through the market of circulating bitcoin

special bit code operation requires a lot of graphics resources, so there are so-called mining machines, as shown in the figure below

this is a miner, which is specially used for mining. Such a miner may not be able to dig a bitcoin a day; The price of a mining machine is at least about 20000 RMB, and mining is a very power consuming project. All the graphics cards are running with full load, and the electricity charge will be very high

so don't blindly follow this kind of thing, it's not something that ordinary people can dig up with their home computers

3. This depends on the situation. If it's a mining machine of the size of USB flash disk, the computing power is only about 1g. This mining machine is a kind of experience machine. Let alone 20, it doesn't matter if there are several hundred. But if it is the kind of professional mining equipment, ordinary household electricity is simply not up, mining machine power and power consumption is very high. Moreover, the noise of mining is very large, and the heat generated is also very large. There must be powerful refrigeration equipment, which also needs power consumption

bitcoin is a consensus network, contributing to a new payment system and a fully digital currency. It is the first decentralized peer-to-peer payment network, which is controlled by its users without a central management organization or middleman. From the user's point of view, bitcoin is much like Internet cash. Bitcoin can also be regarded as the most outstanding three style bookkeeping system.

4. It's hard to say. It depends on the specific equipment you buy. With advanced equipment and high computing power, the price is naturally high. Of course, if you buy a obsolete bitcoin miner, it's much cheaper

if you haven't played bitcoin or mined before, it's recommended not to buy a miner to mine bitcoin. At present, the profit margin of mining is very low, and retail investors have graally withdrawn from the historical stage of mining. Mining is mainly some large mines, which are deployed in some remote provinces with low electricity price

of course, with free electricity, mining is also possible. If you don't know, you can trust me.

5. I suggest you don't go. I'm Lenovo g480 computer. I g for a week and got 0. 000034 bitcoins are not enough for electricity charges. If you want to dig them, you can dig them with professional graphics card machines. Because of different computing methods, it is efficient to dig them with graphics cards

6. Financial machines and tools refer to the machines and tools commonly used by banks and other financial institutions, such as anti-counterfeiting banknote counting machine, banknote checking machine, multiple counting machine, POS machine, intelligent terminal, coin sorter, banknote sorter, bundling machine, binding machine, shredder, ID card identification machine, etc. This paper introces the concept stock of financial equipment in A-share market for your reference only.

7. One bitcoin is now down to $135
one dollar equals 6.14
in other words, 1 bitcoin is equivalent to 828.9 yuan
and according to the latest news, bitcoin has been stolen, so the price will be lower.

8. Washing water is usually provided by many kinds of anionic polyacrylamide and common polyaluminum chloride i83398zz352. The price of polyacrylamide and polyaluminum chloride is relatively low

9. What you said is out of date. Now the pittcoin (the proportion of money g) can't make much money. Go to the second-hand market. If they can make money, will they still sell machines
