People have been talking about the Bitcoin bubble since it started. And it's a very contentious issue if it is a bubble or not. So, let's just not touch that.
Bitcoin will not burst, explode or disappear from the surface of the planet earth. In the contrary Bitcoin will be more valuable because of the constant increase of the difficulty to resolve the mathematics puzzle.
Also, we need not forget the halving every 4 years, this will result in less bitcoin every 10 minutes. So, whether the Bitcoin bubble bursts or not, it will have nothing to do with the 21 Million limit. This is because it gets progressively harder to mine for Bitcoin and as a result, the remaining 7 Million Bitcoin will take until around 2140 to mine.
Bitcoin won’t be all mined out by 9:40am.
