We know about some investors who are not patient enough to hold and they sell once they start seeing their investments in green. But we call them smart as well, because what would happen if that specific investment never rises in value once it came down and that investor would rather regret holding it? Whatever you gain, a gain is a gain and if you see coins pumping after you sell your holdings, then we call it your bad luck and not impatience to hold, because there are so many investors who would fall in your category who also experience the same.
