Safe Haven for criminals and who don't want centralization. Bitcoin is used and dry popular mode of payment in the darkweb. They are free to collect funds without being revealing themselves. Bitcoin is not a safe Haven for people wants stable income. No it doesn't work that way. Because we all know how the market behaves.
It all depends on your perspective if we evaluate Bitcoin only based on its last high of 20K$ we will probably get to your conclusion but if we put aside the price and evaluate it on its characteristics, it's a safe haven.
Imagine something that cannot be inflated, that cannot be controlled by any entity, that cannot be censored by any government.
Well, Bitcoin has all those characteristics, so before you speak against Bitcoin, learn about it.
