well i think Bitcoin is the first cryptocurrency that came on blockchain platform and some say that this is the king of all cryptocurrencies. So it may be right to say that Bitcoin will always be in power because bBitcoin is the only online currency that give the idea and a start up for the other alternate cryptocurrencies on the blockchain now a days.

Bitcoin is the first crypto creation and it is tested through times
