If you are a holder then you must immediately decide for yourself how long you are ready to hold your coins, if your strategy is designed for 3 years, then do not worry now, in order to engage in day trading you need good trading skills, not everyone can profitably trade.
i think we must have parameter, how much we can lost and how much we can tak profit, like trading forex.
so we can manage our profit and lost
