No I don't think it will replace fiat as the governments just won't approve due to the lack of control they can have with Bitcoin. But hey I can be wrong, anything can happen in this strange little world.
yes I agree, in some countries like china, they forbid bitcoins because of hard currency controlled, the number of cryptocurrency scams, usually used illegal transactions and more.
but I also hope the other bitcoin and cryptocurrency can be legalized by all countries, because it can improve the economy of society, like me
