Bitcoin has been mapped in such a way that the supply of Bitcoin will be precise and limited.
According to various calculations, the last bitcoin will be created in 2140.
This limited and precise supply has made Bitcoin so valuable. There is a lot of disagreement about what the price of Bitcoin will be in the future, how long this high rate will remain.But in the midst of so much uncertainty, Bitcoin has undoubtedly opened a new horizon in the field of economics and technology, with its popularity growing day by day, and it is hoped that one day every country in the world will realize its importance.
There's probably a lot of more to be added here, but i'm trying as much as i can to say something new from my own thoughts.
The rest is to learn from those who are old experienced and senior here.
Come to think of it, I am not sure that it's necessary for Bitcoin's popularity. The rate at which Bitcoin is getting mined is what matter in a particular period of time when we're talking about scarcity. If Bitcoin could be mined forever with the halvings disappearing at some point and the rewards remaining the same after that forever, I don't think it would be a major problem. While there would be more and more BTC, the rate at which more of them become available would allow a certain stability. Okay, maybe Bitcoin would then be susceptible to inflation, but the rate could remain very precise because of this limitation on the BTC that can be mined. Maybe I wrong, I can certainly see some problematic points here, but I suppose this could be okay in general (and still much better than fiat).
