This one is really hard bcoz of greed and FOMO, I admit this is one of my flaws
but I know it is possible if you have set your attitude right and have self-discipline.
Being greedy is not bad at all. I mean who on earth does not want to have money. It is the only thing that can fulfill our basic needs and eventually desires. You should always desire for the most instead of more. That will solve the issue of losing control for little gains. As far as the FOMOs are concerned, this issue can be handles with knowledge. Just research about your coin and trust in it.
Humans tend to be greedy but in trading, the lack of emotional control will definitely have negative consequences. The effect of emotional trading will make the profit curve of trading account up-down and the stability will stay away from the trader under these psychological conditions. FOMO is a useless feeling unless there is no chance to catch the lower price in the future and in most times the price reverses back to the level which it started to climb higher.
