If you have a peace of mind, it's so important ,do stress your self.If your trading just have a plan and target for years not for a day,keep playing smart,if you don't have any coin to long or short,set a limit and rest or wait some times and check again ,you may find a coin to buy.
Another think don't catch every falling knife,it may hat you,first do research ,why before you open a position.I take profit 50%-150% according to the coin I bought .
I don't think that it will hit 30 dollars again .
