In recent days, bitcoin has been rising again, reaching a maximum of US $64800 and maintaining a high level of more than 60000.

There is no doubt that this has led to a new wave of discussion on bitcoin.

Among them, the total amount of bitcoin is always mentioned. It seems that there is a misunderstanding.

In fact, the total number of bitcoins is less than 21 million.

The total number of bitcoins is 2099999.97690000.

How does this number come from? It is calculated according to the principle of bitcoin.

To understand, bitcoin is not made or mined. As a virtual currency, it is "regulated".

It can be understood as follows: a program for producing bitcoin, which produces bitcoin every ten minutes on average through adjustment. In addition, 210000 production tasks are defined as a production cycle.

At the beginning, 50 bitcoins were produced at one time, and this production stage lasted for 210000 times. It has produced 210000 * 50 bitcoins.

After completing the first production cycle and these 210000 production tasks, only 50 / 2, or 25 bitcoins, will be produced every 10 minutes from the next time.

In this way, after another 210000 production tasks are completed, only 25 / 2, or 12.5 bitcoins, will be produced every 10 minutes from the next time.

In this way, for every 21 production tasks, the bitcoin produced each time will be reduced by half.

So is it going to be halved?

no, it isn't. When bitcoin was born, it set the bottom line. The smallest unit of bitcoin is Cong, and 1 bitcoin is equal to 100 million Cong. This means that when the 33rd "production cycle" is about to halve production, bitcoin will be found to be inseparable. This is the end of bitcoin production.

So far, the production task of bitcoin has been successfully completed, and no new bitcoin will be produced.

How much bitcoin will be produced at this time? 20999999.97690000.

That's the total amount of bitcoin.
