Do you think there will ever be a time when Ethereum will stop following Bitcoin? The time Ethereum goes up in value is because Bitcoin goes up in value. In the future, will people look for Ether first before Bitcoin? Or will it always be Bitcoin's sidekick

What do you guys think?
Maybe on the right time, there are few chances and one I know is that if the owner of 1 million bitcoin does shows and cash it all out. Selling those massive amounts of btc would lead to the crash of Bitcoin and there the ones would takes it place is thr second in n line which is eth. I don't know for sure, it's just my opinion.
