Why dont you want to sell your coins i dont think there are so many people who want to selltheir coins right now because the price of the bitcoin is not very high at the moment.
Not selling now can be understood as price is not high at a moment, but it doesn't make any sense to not to sell at any point of time as if we never sell them then we will never enjoy profits.
Yep, not selling coins at any rate wont be a wise move as we dont know when the price will start dropping down again so if we dont sell anything even after getting to a good point and then if the price drops again so we will lose a chance to get more profit.
