ETH can't, and won't go down to the level you suggested because everybody trust its network and it's a major altcoin with too many smart contracts already relying on it. But about the talks on ATH of ETH, I believe that it has already seen good highs this year and should not go any higher further till 2021 and should adjust in the short term.
I think the OP already got the idea that $80 level is too low for eth to go back to this value.
We will be seeing more increase in the next coming months.
But if you are a trader or investor, of course you need to prepare yourself with all possibilities that may happen in the future.
It is only you that can take care of your funds and no one else will be responsible for that.
