No doubt that there is no 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 Ethereum, ripple and litecoin.
Do you agree???
I think no because we all know that bitcoin serves as the father of all the coins. Bitcoin serves as the main idea of all the coins because we all know that any coin can be changed or convert to bitcoin. And ofcourse bitcoin era may not be in the high value in the market but I believe that someday bitcoin price will rise too. And it will be always number 1 coin in the market used by many people.
