Emotion is the most difficult aspect of trading. I can relate to your point first hand, but I have found that selling to early hurts way less than not selling and watching the fall. I sold all my EOS at 2x and while it stings a bit it's nothing compared to the position I hold that is 2x and wished I sold when it was 10x. What I'm planning to do going forward is take positions with the plan to sell half at 2x and another half of the remaining at 10x.
