It will never happen. Now, we are waiting for Ethereum that will reach 400 dollars and even more. This is the best altcoin and its market capitalization will grow greatly in 2019-2020. It is worth investing in this crypto even now.
This speculation is almost meaningless and this topic should disappear and become the past when eth is right as you say, it is receiving a lot of expectations and there is a strong growth in recent days, it is still the best altcoin behind only bitcoin. There is no reason for it to fall so deep as OP said, I believe OP has been in a desperate time for too long, which makes him think about too bad cases, but maybe now he felt happy again, eth will continue to go backwards, it will not return to $40
