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?
I do not know why Ethereum prices always follow the price of Bitcoin, it is likely not only Ethereum is following the price of Bitcoin but all altcoins refer to the price of Bitcoin.
Haha, why do you think the price of Bitcoin follow Ethereum, I think it over Bitcoin, or look that. When Bitcoin drops 4 percent, Ethereum drops by 10 to 12 percent
