Meh, With current state Bitcoin can never change fiat currency, for not it's just too volatile. FIAT is a little more stable, but even that is gone after years when inflation happens, not to mention fiat is devaluing itself with everyday use for things that are not there. Services, etc... Also, when bitcoin is down, rich people talk bad about it, when it's booming, they talk nice about it. You just have to follow the money.
