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.
I do not think that Bitcoin is going to be replaced by a other crypto currency because Bitcoin is the most popular one and the biggest one.
It would be weird that Bitcoin would be taken over by a smaller one.
At this stage we don't see any competition to bitcoins but there is no guarantee that the same thing will be followed in future too, as there is a possibility that bitcoin can get replaced in future by some new and innovative currency.
