Soon? by the time you buy "soon" it'll be too late. The time to buy is right now, current btc price is 9400, though it could probably test 8k later today or tomorrow. ETh on the other hand, current price is around $812, could see some support at this price, but most likely it'll going to keep going down, either way, bitcoin and altcoins are on sale right now, anyone who wants to buy should go and do it now.
