bitcoin will never be able to suck all the fiat money, they can just print more without problem
also fiat is already worthless, but you're obligated to use it for the majority of things
if you mean collapsed, i don't think so
yeah that's right.
I think fiat will survive in hundreds years and won't be worthless.
if bitcoin ever reach $10.000/bitcoin, fiat currency won't be worthless either as long as people convert bitcoin to fiat
Fiat will always survive especially in poor countries, where people don't have any idea about the digital world, they would prefer to use fiat for making purchases.
