in panic most of the people cannot move. like a rabbit who see car light people going to be freeze. but this is not a good thing most of the times.
for example; if you are a trader and your hold start to be down. you should definitely sell this coin. if you wait for correction, you gonna lose much more. of course there is a chance you were right first place and coin take the bounce. don't be sorry. not to lose more important then not to gain.
