How many mining machines are produced

1. 1、 bitcoin is an experimental currency, and the consensus of core members is that bitcoin is only a virtual experimental currency. Its existence value is to prove whether money must have thing value or only need a currency symbol. If it survives, and can always be used as a trading chip, then the proof of money does not need physical value, as long as a reasonable currency symbol. If it can not survive, then the proof of money must have a certain physical value. 2、 Bitcoin is "mined" by calculating the results of mathematical problems. I think you can pay for bitcoin to get an answer to a math problem. You know, computing resources are valuable, and many people don't realize it.

3. 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.

4. Hello, according to the different power of mining machine, 20kW power can drive different types of mining machine.
for example, the power of an ant V9 mining machine 4T is 1.05kW, 20kW can drive 19 mining machines
the power of an ant T9 + miner is 1.45kw, 20kW can take 13
the power of a Shenma mining machine is 2.1kw, 20kW can take 9 sets
according to the different power of mining machines, the number of mining machines that can be carried is also different
the above mining machine power data comes from bitfan website

6. You're talking about bitcoin! Because the remaining amount is less and less, a miner can dig less and less money

7. What is the risk of futures
it's not easy to answer this question. Many people just hear that futures are risky, and they shout that futures are risky. In fact, which investment has no risk
people think that futures are risky because futures are margin trading, You can use 100000 yuan to make a contract worth 1 million yuan. Your capital has been magnified 10 times. Then if the market goes in the opposite direction, your principal may be lost. For example, when you buy two hand 704 copper, the price is 55000 (one hand is 5 tons), and the required margin is only 55000 * 10 tons * 10% = 55000. If the copper falls to 50000, your loss is (55000-50000) * 10 = 50000 But I think the risk is completely controllable. Risk and return are relative. There is absolutely no investment with low risk and high return. Investment in an instry mainly depends on whether its game rules are fair. Futures are fair and open relative to the domestic stock market
