I hope this could help OP
https://coinmarketcap.com/All you need to study the market and do some search. Bitcoin remains dominating the market, not ETH. And altcoins remain to follow the movement of Bitcoin, not the one to follow Altcoins.
Do you think it's possible that the Bitcoin price will follow Ethereum price in the future? When Ethereum becomes proof of stake and becomes deflationary, can it happen?
This will never happen at all we all know that the bitcoin is always the number one coin and it's price is much higher than the ethereum or on any other altcoins. So it will never follow ethereum it is impossible to happen. Bitcoin always dominating the market and all altcoins always follow it.
Don't take that seriously as the OP still confuse about what coin is dominating the market. That is to find ridiculous but we just have to try educating him and help him to get familiar with the market sentiment and ranking.
