If we talk about ETH down, it is true that ETH will go down. All of this is due to the genius of ETH (Vitalik) who has moved to handle ETC today. But, ETH will not fall to that depth. I'm sure if ETH falls to $ 50, people will leave.
I expect ETH will remain at the current price until the end of this year, it is the Chinese market that has kept ETH prices so far, no less or more.
