Yes, one of the failures is greed. Humans in general have a greedy nature, so they quickly become arrogant and never care about the risk of losing. Crypto is a risky trade, some experienced people will avoid greed in trading. Many of those who become greedy will regret not taking the opportunity. In trading we must commit to a predetermined strategy, for example, the profit target is something that cannot be changed anymore. If the profit line has been reached, then immediately take it. And don't mind the temptation that the market will go higher, because that's still a prediction and far from correct.
