I am not against selling now, whenever one got hefty sum of profit is the right time to sell. Don't get caught up with your greed because if you hold for too long, then you would have to hold it for another long period of time. Do not hesitate to sell if there is a hefty sum of profit already. Just always remember to rebuy bitcoin whenever it corrects or dumps. If you have not profit big yet, then better hold that until the goal profit is reached.
