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 guess ethereum was made to sustain what bitcoin cannot give. In short etc varies directly to bitcoin. Bitcoin affects ethereum because ethc was made for bitcoin. Etc and btc night have different functions but the thing is bitcoin is still the king and all coins or altcoins varies on what is going on to the bitcoin. That is why. But we can assume that before this year ends, the market will rise.
