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 dont think so, that bitcoin can be replace by any other currency, bitcoin is getting popular day by day. people are entering in the world of bitcoin on daily bases, they are investing their money in bitcoin, some people are also using bitcoin as in place of fiat money, some shops are now accepting bitcoin for shopping, and the government is now taking serious decision about bitcoin legalization, therefore i do not think so that the bitcoin is going to be merge or replace my any other currency.
