I had previously doubted that Bitcoin would be replaced by another currency. But my mind has changed. Because I see there are many other cryptocurrencies that the developers are trying hard to solve the problems in cryptocurrencies. What about bitcoin? We don't know who are the developers and no effort is being made to develop it.
If you don't try hard, your rivals will win. Bitcoin's rivals will win too.
I don't think there would be any cryptocurrency that will replaced bitcoin.Bitcoin is very popular and no one can level up it's value.This will never happen.Bitcoin remains to be the number 1cryptocurrency.
Major alt coins are actually closing in on Bitcoin and although many still think that Bitcoin is at the top, it won't stay up there forever.
