All because ETH couples still follow BTC and if BTC goes down then ETH follow suit, but also depends on community holding ETH because market will move if big community decide to sell or buy coin that will be in market, small capital and do not follow the premium community, better just bear the ETH that we still hold and believe the price will definitely come back with a high price. Just give it time to do so, all cryptos are in a adjustment period BTC especially. ETH may even surpass BTC in the long run because it has the better tech lets be honest. BTC will eventually hit a wall because of its tech hence why things like pay with amazon via BTC does not exist. 1% of amazon traffic per seconds is higher than what BTC can per second and that would not be including all the trading and personal BTC moving. So eventually there will be a transition from the old tech to the new.
