Ethereum display card miner for sale

1. Generally, it's not recommended to buy mine cards. If you're lucky, it may be OK to use them for half a year. If you're not lucky, it's not impossible to have problems when you buy them home.
some mine cards look good because there's no st in the mine machine, but because the hardware has been overused, all kinds of unstable problems may appear when you play games on the computer, And manufacturers generally do not guarantee the quality of mine cards.

The miner is better

1. the electricity charge for mining with graphics card is very high, and the performance is not high, so it can't even earn the electricity charge

2. mining is an investment more than time and speed. We should try to dig more money in the shortest time. Therefore, the professional mining machines of BTC now stress the characteristics of simple operation, small footprint and low power consumption. For example, Yingtai has developed a professional mining motherboard with a computing power of 23.488g/hash, and the proct model is btc-24gh< br />

3. 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.

mining machine risk

1. The problem of electricity charge

in order to make the graphics card full load for a long time, the power consumption will be quite high, and the electricity charge will be higher and higher. Many professional mines at home and abroad are operated in areas with extremely low electricity charges, such as hydropower stations, while more users can only mine at home or in ordinary mines, so the electricity charges are not cheap. Even in a certain residential area in Yunnan, there was a case of crazy mining, which led to a large area trip of the residential area, and the transformer was burned

2. Hardware expenditure

mining is actually a competition of performance and equipment. Some mining machines are composed of more such graphics card arrays. With dozens or even hundreds of graphics cards, the cost of hardware and other costs is very high, and there is a considerable expenditure in mining

3, currency security

the withdrawal of bitcoin requires hundreds of keys, and most people will record this long string of numbers on the computer, but the frequent problems such as hard disk damage will make the key permanently lost, which also leads to the loss of bitcoin

5. Is it going to be a large mine or a private family
it's up to the family to dig. Large can be prepared on a host of 6 or 8 graphics cards, need rx570 (580), or gtx10610170. Then in the preparation of 20 hosts or more can make money. At least 10

6. No one can tell clearly whether the price of the video card miner will go up or down, but it is irresponsible to say so, because the commodity price is determined by the proction volume and the relationship between supply and demand. If the supply exceeds the demand, the price will rise. If the supply exceeds the demand, the price will fall
if you have to buy it, you can do it directly, because what you like will not be too expensive.
however, there are risks in mining, so you need to be cautious in investment

7. Naturally, there are only second-hand platforms like salted fish or 58. But there are a lot of knights in it

8. This mobile phone mining is not free, but you can also play it for free, but if you play it for free, you have to have a lot of people before you can play it. Moreover, if you use this mining machine, you have to spend your own money to buy it, and then you can earn profits.

9. It's very troublesome for mining machines to be installed, and it's not cost-effective to pick mines where electricity is expensive. It's recommended to find a miner factory that can be trusted. You can take a look at Feixun's Ethereum miner C8. It's very popular recently. Feixun provides trusteeship service. It doesn't need to assemble miner itself, debug miner itself, or find miner itself. Moreover, the maintenance of miner is also covered for you. It provides one-year warranty service for graphics card. All it does is two things: pay and check your Ethereum wallet, Save time and effort, let you mine.

10. It doesn't matter. First of all, I'll take photos of the bar code and N / s code of your graphics card to store evidence. Second, I'll take a complete video of the graphics card as evidence. I also need to take photos when I send it by express mail. I need to see if the buyer has real name authentication and what the sesame score is. If the credit is good, I'll deliver the goods, if not, I'll cancel the transaction,
