Of course it is easier said than done. lol. The most difficult thing for a non-trader like myself is usually: when to sell? Sometimes the decision to buy is pretty simple, you see the coin down and then you buy. But the selling part is usually the most difficult one, for me. Coz you don't know if the coin might go up some more or when it slightly falls you think it's just temporary and it's gonna go up again lol. Then it falls some more. Gotta love the HODL game.
