Does it make sense to believe that Bitcoin could one day be replaced by another cryptocurrency, that is, a cryptocurrency that really does make Bitcoin obsolete?
I think it's possible. There are a lot of altcoins that are far more technologically advanced than bitcoin, but they are not replacing bitcoin, which is still the king of the state-owned cryptocurrency. I don't think there will be an encrypted currency to replace bitcoin in the short term, and we need time to test it.
