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?
My friend I have also an Ethereum holdings and this time the value of it was so down.But it doesn't mean that I'm down also because someday it will rise again.
