Yes, it can be good sometimes. But this is a personal thing, depending on the gambler's own characteristics. Some people prefer to cash out early and feel comfortable doing so. It depends on what makes you happy when gambling; it's not always the fear of losing everything, but something already established from the start.
I believe that patience is absolutely important in life, whether in play, at work, or in personal relationships. It's not just a question of when and how to cash in, it's a way of life.
Rushing and being impulsive leads to nothing but making mistake after mistake.
Unlike many people here (and especially in these pages), I don't believe the idea that hodling Bitcoin is a sure thing, and I think about it not only as an investment but in some sense as a way of gambling too. And, although I agree that lack of patience makes you miss great oportunities, like the mentioned by the OP, or like the case of those who sold BTC early, one must also consider his own situation and needs, because as we say in Spain "it's better a bird in your hands than a hundred in the air".
