I have realized, that one of the hardest things in trading for me is to talk or force myself to sell altcoins with a price loss, to try to recover losses by other cryptocurrency growth. As not a frequent trader or investor, I find it mentally hard to sell with a loss. For me it was always better to think that altcoin I have bought and its price went down as a fail investment and come to terms with losing money. I have been holding dogecoin for long, bought them @33 cents. Saw today, that they have made already a nice growth, but still not enough, so I have decided to to sell and buy bitcoin instead. Previously, I would have held them till price returns to 33 cents, sell and forget like a bad dream. Forced myself to jump from dogecoin to bitcoin and keep holding.
