You are kinda wrong about this.The newbies don't panic sell their coins,because some "influential" guy told them to do so.They panic sell because the prices are already going down.The newbies act like a crowd driven by emotions like fear and they have no market strategy.
i know what you mean but you said it wrong.
newbies are newbies because they panic sell when
the prices have already gone down. in other words the main characteristic of a newbie panic sell is selling when it is too late. otherwise selling because price is going down is not wrong. in fact that is what every experienced trader does, you see the drop and sell before it is too late.
