Panic sell is not bad idea actually. The reason is if price falls down more (it will), you can buy it cheaper. Eventually you will end up with more coins.
So, selling coins at right moment and purchasing it back can be very profitable.
I think it's possible if there is a big problem like this ,, but that's not what I mean ,,, if there's okay but there's a bunch of people who want to get the price down is playing tricks to make panic ,, for then. That is my opinion above
