Maybe yes or maybe no. Ei her way such an altcoin must have something Bitcoin does not have. But I doubt there's any chance an altcoin being developed will take over the place of bitcoin. Bitcoin is like the king of cryptocurrency so I like to think.
Yes, a possibility can indeed happen to Altcoin, only if to have something that is not owned by Bitcoin on an Altcoin, it seems to be a little more difficult to realize, because the average Altcoin developer takes its reference to bitcoin and the blockchain system owned by bitcoin, so this will certainly be a little difficult for Altcoin.
