Of course it will take time but I think it will be as altcoin as bitcoin.
There will be even more than one because the functionality of the banks will be reduced and such digital money will be valued.
I dont feel the same way in my opinion as the crypto grows bitcoin price will also grow and it will always outperform altcoins as because most of the altcoins price is related to bitcoins price action so i dont see it happening anytime soon.
