I also decided to just hold the coins as I can not control my emotions. I've been studying trading strategies for a long time, but in practice I always get only a loss of money 
If you have invested in shit coins and hoping to price to pump then it will never happen as the price of those coins can crash with an blink of an eye and in that case you will surely get panic and sell your coins at low price but if you have invested in good coins and if price goes down then there is nothing to worry as those coins have potential to bounce back but you need to make sure that you hold your coins for the right time.
