The total number of bitcoins is 21 million

in 2009, when bitcoin was born, block reward was 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the block reward will be halved to 25

when the total amount reaches 15.75 million (5.25 million new output, i.e. 50% of 1050), the block reward will be further halved to 12.5. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to about 21 million

6. Online banking of Bank of communications has the function of settlement and sale of foreign exchange, but it must open the registered version of online banking, SMS version / certificate version. It can exchange RMB and foreign currency in financial management, but it is not real-time. There will be an approval process, but it will be very fast.

7. No, only financial constraints on your purchase
the risk of all financial procts is that after the depreciation of the financial procts, they may not appreciate or return to the price when you bought them on time
that is, your property is trapped in it, and you are unwilling to sell it after devaluation. Wait, I don't know that you can't get it back until the end of the year. Maybe, just like China's stock market, you can't stop losing. The more you wait, the more you lose

8. It's true that there is a threshold, but it's too low. For example, the okex exchange I use can buy bitcoin for at least 10 RMB. It's not too much to say that there is a zero threshold.

9. I don't think so, but at least it costs a few hundred yuan

10. I don't think so, but at least it costs several hundred yuan. It's too little for you to play. It's not enough for the service charge.
