I think its is totally the opposite of it. It might be the best time for trading since the prices are low many potential investors must be showing good interest in buying so good coins that might have some good value in the future. Those who trade crypto with small amount hoping to get big will get stuck from all the bearish price and finally panic sell when he can't handle the FUD
I don't know if you're talking about a permanent exit, but exiting trading is not a simple decission to take at once. If you will exit trading, you should select the best time for this. The term best is not objective, it's very subjective.
