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?
Ethereum had entered a serious upward trend over the past year due to the intense use of ICO projects and the high return on these projects. Especially in the direction of the rapidly rising demand, the price reached a very high level with the effect of a bullish period. In the meantime, the Ethereum price went into a rapid decline as a result of the ICO projects being out-of-purpose, intensively on the day-to-day basis of projects and meeting the funding needs of successful projects. Ethereum, which is traded well below its deserved value with its high supply and bull effect, seems to be unable to recover its price for a long time. I would like to remind you that there will be changes in the price recovery process depending on the ICO projects and I do not want to be reminded that this decline crisis can be turned into an opportunity.
