Oh yea dominance for certain crypto's will fade but will not die as this is pure REJECTION OF FIAT MONETARY system which is on going right after 2008 crisis, Central bankers are on bandwagon printing money as if there is no tomorrow which includes Japan yen, Euro and US dollars and these FIAT money should die before that we will see so many cryptos popping and only that will survive which has MINING capabilities.

We don't know which will overtake which one as its evolution process in this space too and we are lucky we are early on in this..... before every common man knows about this space and has truly transaction capabilities for daily usage as the regular money does.So we are long way in this space which i would refer baby steps !!!
