I think it is not impossible if Ethereum can beat Bitcoin someday, who knows mate? I know that Bitcoin is like the mother of all crypto coins and Bitcoin has the highest market caps so far. But this cannot guarantee Bitcoin to stay at the number 1 coin in coinmarketcap. Although the possibility of Ethereum beating Bitcoin is very small, it is not impossible, right? Everything in crypto space can be changed and no one knows the future of those crypto coins.
