Wow, interesting stuff. That's quite a lot of profit there. How many years precisely did this take? It seems I'm not even anywhere as experienced as you. So, it feels weird that I should be on the advising end. But then, I will say what I would do if I were in your shoes. I think I would sell a good percentage and keep some in the system. You also see how much profit you've made over time. But one must also be careful to know where to draw the line. So, sell some, keep trading the rest. More like a win-win situation.
