No way. Bitcoin has something like the benefit of being the first crypto, so it won't be replaced by an alt one day.
The possibility exists, but it is very difficult for any Altcoin, because what it is competing with is the king of coins, namely Bitcoin.Don't be too sure about the saying that Bitcoin cannot be replaced forever. we don't know what will happen in the future or will happen in the next 10 years. 
Indeed, yes anything can happen in the future, but you should also know that Bitcoin is almost 11 years old in crypto and it is clear that it will not just stand by even though it is very popular at this time, meaning Bitcoin will also grow in the future, because if Bitcoin does not develop, the same as the world of cryptocurrency is over.All have the right to say what happened to Bitcoin. let's see together what will happen to Bitcoin. whether Bitcoin will have new ways or new developments to surprise many.
