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?
No, I do not think of going to another crypto currency. All other altcoins are bound to bitcoin. If the bitcoin ends, it ends up in the other crypt currencies.
Of course it is not easy to predict the future. We do not know what will happen in the future.
i also do not think that bitcoin can be replace by any other crypto currency, because bitcoin is still number one crypto currency and there is not a single currency so close to bitcoin which can compete and overcome bitcoin, therefore i am hopeful that bitcoin will still remain as number one currency of the world.
