Panic selling is never worth it anyways because people can lose a lot through panic selling i do not understand why people invest and have patience and then panic sell everything just because it is down for just a couple of hours.
Sometimes it's good to panic sell but it's not worth if you'll going to do it with bitcoin. This can be applicable to those alt coins that are going to be dead anytime.
This is something that's very normal in the world of cryptocurrency. When traders are seeing some alt coins that are pumping they'll convert their funds for it.
And if they see their coins are dumping, they'll mostly going to cut their losses.
