How is the number of bitcoin fixed

1. The mining rule of bitcoin is defined by mining rules, which is 50 bitcoins every 10 minutes, halved every 4 years, and the minimum unit is 0.0000000 1
09-13 years, 50 bitcoins every 10 minutes
13-17 years, 25 bitcoins every 10 minutes
17-21 years, 12.5 bitcoins every 10 minutes
...
after several years, 0.0000000 1 bitcoins every 10 minutes (reaching the minimum unit)
four years later, it can not be split, No more mining, no more bitcoin, no more bitcoin

2. No, these bitcoins are just out of circulation. The total amount remains unchanged

3. Yes, the total number of bitcoins is 21 million, and the mining was completed in 2140. Bitcoin is a consensus network, contributing to a new payment system and a fully digital currency. It is the first decentralized peer-to-peer payment network, which is controlled by its users without a central management organization or middleman. From the user's point of view, bitcoin is much like Internet cash. Bitcoin can also be regarded as the most outstanding three style bookkeeping system.

4. Due to the decentralized programming of the bitcoin system, only 25 bitcoins can be obtained every 10 minutes. By 2140, the maximum number of bitcoins in circulation will reach 21 million. In other words, bitcoin system is able to achieve self-sufficiency, resist inflation through coding, and prevent others from destroying these codes.
