An investor should never ever let his emotions affect himself. That's the most dangerous thing an investor can do to himself, losing his control over his emotions.
Sometimes you need to be happy with what you have or what you made. Sometimes you need to know when to leave the table.
I know it is hard, I know it feels like you are leaving the money behind but it is that feeling which forces you to make mistakes.
I guess that's a feeling everyone will experience at least once in their crypto investment journey. We must admit that it is difficult to control greed, but if we do not control it, the end result is loss. Always have a plan and goals when investing and always remember that we are here to make a profit, called profit only when the money is already in our account. We should be grateful for what we have achieved, only by being grateful can we control our greed.
