Panic selling is probably the worst thing a trader could ever do with BTC. That happens because people invest and buy more then what they can afford to lose because If they didn't buy more , they simply wouldn't care , have patience and wait whatever time It takes until It raises again.
People who bought more then what they can afford to lose are always in panic and the least drop in the price could make them panic sell and that could result into losses , however If they waited , It could've go up again.
