For me, I wont sell everything, because Im a fan of saving. So if the point comes that I would sell, but not all so I still have the remaining in my wallet for it to grow over time.
Actually you are a true trader then. A true trader always needs to have a good patience and skills to wait and don't ever try panic sell in any situation he faces. You might truly have a good profit by holding your coin till the end and by selling them in parts to make your profit stable. Trading is not for short term and can never give you profits if you are planning to sell it fast.
Holding is the key for success and you really need to forget about the money you invested into trading. Only then you can have good profits in trading. Hope most of the us might not be selling their coins in panic giving them looses.
