you should have dumped ETH as soon as price went down from $12 to $11.99 and not wait until the very bottom to sell.
right now it is certainly a bad situation going on because people have been cashing out of ETH and it has not yet stopped meaning the price can still go down. and as far as i can see there is no upcoming pump for the time being.
the only way that OP can get his investment back is that if he gets lucky and bitcoin price stops rising and becomes stable like before. then it would be another golden time for altcoins and we may even see pumps again to previous prices. but other than that i don't see any way because as bitcoin price rises, ETH to stay the same price has to go down in ETH/BTC and that will cause people to continue their dump both because price was going down and also to get more bitcoin and join in the bitcoin price rise.
