When I found out about the bitcoin and started trading, I read the forums and there I saw the advice I follow: if the price falls, you either need to sell at the beginning of the fall or just HOLD
You are exactly right specially if you are new in btc community. Many people do panic and all are unreasonably dumb since they think that they can gain if they sell in panic times. As of now the best strategy we need is hold if in dump or sell in the beginning time.
