You can't compare both because bitcoin is a breakthrough of centuries, there was no digital currency until bitcoin was invented, Ethereum was just invented to improve some things and bring more innovation to the crypto space, both are great coins and started below a dollar and today they are worth a alot of money, also whether you like it or not eth or other altcoins will always follow bitcoin trend, it's never going to stop.
Yes, I agree with you, because Bitcoin is the forerunner of crypto, without Bitcoin maybe ETH wouldn't exist, Bitcoin's decline and increase are always followed by other Altcoins, and until now it's still like that, indeed ETH has grown rapidly at this time but he hasn't able to shift Bitcoin.
