Besides ant miner, which one

1. At present, the well-known mining machinery manufacturers in the market include bitmainland, Jianan Yun, etc., but now the price of bitcoin has fallen more, and the electricity charge is higher. Mining is not cost-effective. You can directly buy bitcoin as an investment in bitnet exchange.

3. Mining machine manufacturers have gone through several major reshuffles. At present, the more active mining machine manufacturers are Ajie mining machine, ant mining machine, and of course, several well-known foreign mining machine manufacturers. Avalon, the earliest miner in the coin circle, and roast cat have disappeared. On the one hand, the upgrading speed of mining machinery is too fast, on the other hand, the strength of the R & D team has been unable to keep up with the needs of the times

however, each miner has its own advantages. It doesn't matter whether it's good or bad. The scope of application is different. Some mining machines have high energy consumption, high computing power and low price, which are suitable for users with low electricity price; Some mining machines have low energy consumption, high efficiency, high price and high electricity price. Of course, you can also go to bitcoin home to check the recent mining related reports.

Hello, there are many Shenma mining machines and ant mining machines in bitcoin mining machine market at present.

if you buy a mining machine, you should first consider the computing power and cost of the mining machine. If the computing power is large, the yield of coins will be higher, and the cost of low computing power will be lower.

it is suggested that you visit bitfan website to check the mining machine market, The figure below shows the market comparison of bitcoin miner on June 11

if you have any other questions, please ask me, hope to help you, thank you

5. All very good, for example, my ant mining machine S19 pro in NB cloud mine has a service life of 30 days, the daily operation and maintenance cost is only 0.00012317 BTC / share, while the monthly net return rate is 0.00003983 BTC / share.. If you don't understand, you can continue to ask

6. There are many ways to mine bitcoin, mainly in the following ways:
1. Direct exchange purchase, such as fire coin, coin security, buybit, OK and other digital exchanges. Although buying bitcoin through direct exchange is the most convenient way, you have to find the right time to buy it. Buy high may be cut, so it is best to buy according to the market low. At the high point, you can also sell bitcoin, which is a value-added investment
2. Mining machine mining bitcoin, this way to get bitcoin is the most primitive, bitcoin was originally computer mining, now it is a professional mining equipment mining - bitcoin mining machine. The better bitcoin mining machines on the market are Shenma, ant, Avalon and so on. However, the mining machine mining threshold is relatively high, which the group owners should pay attention to
3. Cloud computing power mining is actually the mining method after the mining machine is split, and the digging of bitcoin is actually the factor of computing power. Because mining machine mining threshold is relatively high, so many mining machine manufacturers will split mining machine into a piece of computing power, sell to users
4. It is a new way to dig bitcoin. It mainly corresponds to a 1t mining machine with 60W power consumption. Because of cloud computing power mining, the cost of leasing cloud computing power will not be refunded, so there is a way of mining with certificate of deposit of cloud computing power, because the certificate of deposit can be traded in the end, which can recover a large part of the cost of computing power for users. Now, Xbit is the first innovative miner. Others like VC are OK
investment is risky, so don't be blind

7. In my opinion, if it reaches 10nm, the movement of the electron will have a great impact on the normal operation, which will greatly affect the yield of the proct. As far as I know, there is no good process to solve this kind of problem. Therefore, in the short run, it is better to consider expanding to three dimensions than to increase the plane density. It may be a practical method to forget the multi stack scheme proposed by which company in the front-end time.

如果有需要，自己太添加，就在那个switch里面，还有宏，
但是不能超过你定义的类型的最大值，否则会出错哦
汉字部分自己改把
