Probably selling would be the best thing to do when seeing a serious drop on the price of the token you are dealing with, a few rises in price could happen too but at the moment that is pretty much unlikely.
if you have a backup token and many of the tokens are sold, it doesn't matter, because the price goes up and down erratically, so sometimes it rises and sometimes drops, we have to be patient and see the price of the tokens that are going down
