I have 2 different ways hiw to handle this. I know impatient is need to be released from our mind since its bad effect to our strategy but sometime is good to sell early to minimize loss. First if we have good studying the project, we know the team, community and all about the project and we think it good then hold is not bad idea, its a must. Second But if we know just half information or maybe less then sell it in low is not problem to avoid more loss because it can be lower again after.
