I get your point about patience and not to sell our coin, but have you been faced with a very difficult situation, let’s say health situations and all you have to do is choose between your health and your coin?(I hope to see your answer pretty soon)
If you are investing in Bitcoin with a long-term goal and suddenly you are faced with a serious health challenge and it happens that you need to sell your Bitcoin investment to save yourself, then you are free to sell your Bitcoin and save yourself because as long as you are alive, there's a big hope for you to invest in Bitcoin again when you are fully sound and okay. But if you want to sell your Bitcoin because of the little profit you see, I agree with OP: we should be patient enough and hold our Bitcoin investment for a very long time because that's when we are guaranteed to see good profit from Bitcoin investment.
