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 
yeah it happens to me too and I can only hold and wait for prices to rise again, trading is sometimes sucks but I try to be patient and control my emotions
If you think and feel that trading is not your cup tea then leave it. Forcing yourself to things that you really don't have patience and don't like to do is just a waste of time. Just hold your coins then wait for the profit. But you should also accept bthe fact that in holding the return of investment is quite slow. So don't expect.
