I really taught this year was for Ethereum but what happen?

I'm so disappointed holding it. Why did Ethereum go with btc flow? Everytime btc falls it falls also. Im rooting for it since its is an open-source, public, blockchain-based distributed computing platform and operating system featuring smart contract. If the erc20 token using it has high price then why is ethereum price not directly proportional?
In your own opinion?
There is the true that the impact of Bitcoin is still too great with this market, so when it goes down, will pull almost whole market down. This thing will decrease when BTC Dominance is lower
