You compare incomparable! Bitcoin and Ethereum are completely different assets. Bitcoin is the father of all cryptocurrencies and it leads them. Just look through the markets history! When BTC pumps, alts start their growth also. When BTC dumps, all alts also dump. These processes are permanent.
True, it is clear that the two will not be comparable in comparison, because the first to be born will still be the King of crypto coins, namely Bitcoin, and those born after that are Alternative tokens that often have an influence when Pump and Dump on Bitcoin.
I, too, believe bitcoin has a great future, but also understand that Ethereum is bound to take its place under the sun as the forefather of all smart contracts !
