honestly think this is not gonna happen, the normal currency's are just too big to take over in my opinion.
Maybe if the normal currency's will get smaller its possible but I do not see this happen at all.
Me too I don't think that this is going to happen because the use of fiat money has been established for a lot of time already.
But I would say that there is going to be a chance if the government will implement will be used as secondary currency but no the primary.
This is more feasible than making fiat money lost.
I am using fiat 24/7 and I am happy with it and also I am investing and working for bitcoin, if you will see that both had given me comfort so why would I choose to replace money with my bitcoin when I can use both to have convenience, the answer is pretty simple. It will not happen..
