There's no good decision if someone is in panic and it can only bring bad decision.But I think that when you have more experience, you can control your emotion better.Do not give any decision when you are lack of information.
Well panic is one of the most common attitude when it is in dire situation. Most of the people panic if the coin is falling down, which is a bad habit. If coins price falling down you dont need to panic, relax and trust the coin. Be patient because it will recover.
