Note: Taking your profit does not mean selling your entire portfolio; it means taking profit; retaining your capital
You can always buy back the low
This is absolutely correct.Do not at the first green color on CMC immediately sell all your capital.Personally, I try to sell 50% of my assets at a good price.But after selling everything you can then very much regret.I can say by personal example that I really felt sorry for many times when I sold absolutely everything.
