Is there 21 million bitcoins

1. 1. According to the bitcoin mining mechanism, it will eventually be infinitely close to 21 million, but it will never be reached
it can be roughly understood as the relationship between 0.9 (9 infinite cycle) and 1
2. Even if there is only one bitcoin left in the world, it means that there are 1000 0.1 bitcoins and 100000 0.01 bitcoins in the world
let's assume that the function of bitcoin is equivalent to that of gold as a currency anchor (in fact, it also has this function). You will understand that there are 21 million bitcoins in the world and only 0.1 bitcoins in the world are the same. The currency itself or bitcoin

for example, if the number of bitcoin in the world is reced to one tenth, the market price of bitcoin should be 400000 yuan (to understand this needs a certain economic basis)

so whether bitcoin is in circulation or not has nothing to do with the quantity.
2. According to the legendary algorithm, bitcoin has an upper limit of 21 million. But you know the algorithm. Although it's very difficult to make adjustments in theory, if you (the legendary top trading institutions with trillions of wealth) really want unlimited, it's a matter of minutes

theoretically, 2100 trillion, or 250.899. In terms of selecting this value, this number is far less than 264-1, which is the largest integer that can be stored in the form of standard integer in a computer. If it exceeds that value, the bitcoin value will return to zero like a odometer

but this is only theoretical, just theoretical. Just like the previous IP address regulations, no one expected that V4 would be used up so quickly. Now it is necessary to use V6. This so-called "maximum integer that can be stored in the form of standard integer" may be broken by the technology upgrade one day a year later, followed by the collapse of the whole bitcoin computing.
3. The upper limit of bitcoin is not the exact figure of 21 million. 21 million is calculated according to the mining rules
in the first four years, 50 pieces were g out every ten minutes: 50 * 6 * 24 * (365 * 4 + 1) = 10519200 pieces
in the second four years, 25 pieces were g out every ten minutes: 25 * 6 * 24 * (365 * 4 + 1) = 5259600 pieces
according to the sum formula of infinite equal ratio sequence, the final total amount is infinitely close to 21038400 pieces (10519200 * 2)
as long as the mining rules are not changed, the number of bitcoins will never exceed 21038400
4. There is an upper limit to the number of bitcoins, mainly because there is an upper limit to the solution set of the algorithms involved in the program. The algorithm is very complex. In theory, no computer has such powerful computing power that it can solve 51% of the solution set, that is, no one can control bitcoin

so far, the number of bitcoins has reached 12 million. To be exact, the maximum number of bitcoins should be 2099990000, but in fact, the current mining (mining) process is quite difficult - no less difficult than connecting 1000 home computers, and then continuously calculating for a month, it is not possible to dig out a bitcoin

I hope I can help you.
5. Yes, when it was released, it showed that its constant number was 21 million. With the passage of time and the efforts of the miners, the number left on the market is less than 2.5 million.
6. It's the second one. According to the previous block information, root node information, real-time mining time, difficulty and random value, the random string is generated by twice hash256 algorithm calculation, and is allocated and recorded when the verification is passed.
7. At that time, Nakamoto set a maximum of 21 million rules
8. This algorithm is designed in such a way that the upper limit is similar to the limit of an infinitely proportional sequence, and the common ratio is 1 / 2
9. When the global financial crisis broke out in 2008, someone published a paper under the pseudonym of "Nakamoto Tsung", describing the mode of bitcoin. Compared with legal tender, bitcoin does not have a centralized issuer, but is generated by the calculation of network nodes. Anyone can participate in the manufacture of bitcoin, and it can circulate all over the world. It can be bought and sold on any computer connected to the Internet. No matter where they are, anyone can dig, buy, sell or collect bitcoin, And in the transaction process, foreigners can not identify the user's identity information. In 2009, bitcoin, which is not controlled by the central bank and any financial institutions, was born. Bitcoin is a kind of "electronic currency", which is composed of a series of complex codes generated by computer. New bitcoin is manufactured through preset programs. With the increase of the total amount of bitcoin, the speed of new coin manufacturing slows down until it reaches the maximum amount of 21 million.
