Leave the market after the value has falls 50% seems to be the wrong decision, so it's better to keep holding it. Unless you are very confident if the market conditions will continue to get worse until the end of the year, maybe leave the market from now on is the best decision.
I have the same opinion as you. Leaving the market is not a good choice, I think. If we are leaving now, then what we get from it? Just a loss?
Then it will be better to wait, although we don't know for how long we should wait.
