If eth will be @ 50 usd therefore bitcoin will be @ 2k USD . Too low prediction is ok but what I am saying is that ethereum will be at cheap price if bitcoin will also suffer and the rest altcoins .
Ethereum will not go down to $50 because all the investor will not let this happen, i am sure that ethereum will only dump to $170 but it will really recover again on the perpect time, and i have a big hope that ethereum can go back again up to $800 this year.
