1. Today's smart phones are easy to heat up and consume power quickly. Because the software running on mobile phones is relatively large and can support multiple software running in the background at the same time, mobile phones are easy to heat up and consume power. You can use Tencent's acceleration rocket to end other background applications with one click when playing mobile phones, Keep a program running, the phone will be more power-saving and not easy to heat.

2. For example, when I buy a miner with 20000 tons of computing power, the cost is 1000 tons. The one who sells cloud computing power is to buy a machine with 2000W, 20 tons of computing power, 1000 tons of computing power. He sells 13001500 tons of computing power. In short, cloud computing power is not reliable. The one who sells cloud computing power is to earn the price difference of mining. It's better to buy a miner to dig

according to the current output, the global output is only 3600 bitcoins per day. Even if there are 1 million machines in the world, the average number of machines per year is only 1.3! Don't talk about making money. I don't know if I can get back to the capital only after a long time. The real money makers are those who sell mining machines. Let's stop now, it's still time

4. I've never heard of the S91 miner.

forget it, but as you said later, is this miner 5T? Why do you buy it back? It's far away. This miner is not enough for electricity expenses
at present, mining is basically based on s19pro 110t. If the electricity charge is higher than 40 cents, it will be a loss of money.

5. 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 At present, the profit margin of mining is very low, and retail investors have graally withdrawn from the historical stage of mining.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.

If we use pure mathematical calculation ability to compare, human's achievement is much worse than that of computer, such as the factorial of 1000, which can be completed in less than half a second with ordinary home computer calculation, and the result must be correct; If we calculate the factorial of 1000, I'm afraid we can't finish it in one month. Even if we finish it, the result is basically not correct

human brain can directly process a lot of analog signals, and human brain has the real sense of "intelligence", which is currently impossible for all computers

The figure below shows the factorial result of 1000 calculated by the computer. If you look at this number, you can see why people are wrong... (PS: if this result is expressed by scientific counting method, it is about 4.024 times 10 to the power of 2567)
