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.
What do you mean about investor? basically the majority of them are only following the market and that looks so possible to see the price of ethereum will be jumping down again in the future. Consider the fall of bitcoin still not yet ended.
Without a big bubble and don't expect that will be so easy to ethereum will jump to the $800 rate again. It may take a few years.
