It can be helpful to have a plan for what you will do if it doubles in price. Some people suggest selling half, because then you have got your money back and any further gains are pure profit. If I still "like" it, I usually prefer to sell less than that (e.g. 30%) and then I will sell a few more if it triples in price. But it really comes down to your temperament and what allows you to make money without having too many feelings of regret. For example, if it doubles in price and then falls back towards the price you paid, or if it doubles in price and then quadruples, how will you feel?
