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 doubt that there is any other cryptocurrency or altcoin that can supersede the bitcoin. At least not for the next 5-10 years. Of course there are many rising competitors like ripple and litecoin. The newest addition to the list of its competitors is Ethereum. Ethereum has launched its own cryptocurrency called Ether that showed an exceptional growth last year making it the 2nd most popular cryptocurrency of 2016. And for all one knows, Ether is the only currency right now that owns a slight possibility to outpass the bitcoin in coming years. The biggest accomplishment of Ethereum perhaps is the support from some leading organizations like Microsoft and IBM. Microsofts US based financial team is now working with Ethereum to offer blockchain as a service to various business firms and financial institutions.
Although, we must not forget that its been just a few years since the bitcoin came into existence and theres still a long way to go. And as the time goes by, we are going to witness many other astounding aspects of this virtual currency.
