It is not suggested at all because you can make a lot of loss with panic selling i would suggest to just wait till it grows again and hold your coins if it goes down because it will go back up in fact i would even buy more bitcoins then.
Yes, panic selling will gives you loses. It is best to think twice or more before selling of your coins. When price drops wait for the price to grow and atleast you can earn when selling. Yes eventually price will recover and it is normal that fluctuates daily.
