I'm sure this was mentioned in this thread but, people work and have to be paid for the work they do. I don't see that happening in bitcoins anytime soon so i don't think fiat will disappear unless something drastic happens.
What drastic action would be needed? Are we talking nuke wars, are we talking about red light district hoes taking bitcoin as a form of payment. Speak up dude because im trying to understand what you're saying but Im having problems
As to me, the most "optimal" drastic action that could help Bitcoin is something which would heavily undermine the faith of people in the government and, consequently, their faith in the monetary tokens that this government happens to issue, without seriously damaging the real economy at the same time. So far the best instance of that was the Cyprus hair-cut, though it was rather constrained and limited in its effects...
Something like that but on the scale of, say, whole Europe would work much better
