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 is how it was designed by Satoshi.
This limited and precise supply has made Bitcoin so valuable.
Not just bitcoin, every asset that is scarce, like Gold will make it valuable overtime.
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.
It's not disagreement, it's prediction, wild educated guess so everyone has his/her own thoughts on what the price will be in the future. You also forget one thing, blockchain, it's the technology behind bitcoin and I think it will also influenced how data is to be stored.
