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?
This is possible if any altcoin has the potential and attracts the trader as well as the investor who cares and invests in it. I believe that bitcoin can not last forever and it will be beaten by a better altcoin.
I agree with you, bitcoin will not always be liked by investors. bitcoin will disappear slowly as the number of bitcoin worldwide decreases. I think the bitcoin will run out but it takes a long time. after the bitcoin is lost then the best altcoin will hold the crypto currency.
