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 do not think that Bitcoin is going to be taken over by a other currency because Bitcoin is the most popular one so it would not make sense.
It would make more sense if Bitcoin took over the other cryptocurrencies.
bitcoin is the most popular coin for now, but for the next year, we still don't know, bitcoin already took over the other crypto currencies that is why bitcoin is the top in all cryptocurrencies, but that doesn't mean bitcoin can't be replace, its all depends on the users, if we all keep using it then bitcoin can survive at the top
