No I do not think this will happen but of course never say never because you never know it of course.
I think that its gonna be hard the other currency's are already so long in the game.
I also do not have the feeling it can do this, the other currency's are indeed longer in the game but are also way too big.
Banks will also not let this happen in my eyes so that is another reason why its most likely not gonna happen.
Another reason is there are many fiat available. Like every country has its own currency but there is only one single bitcoin
