Most of the people who are with the opinion of selling all the bitcoins are the ones who haven’t recognized the true potential of bitcoin or who are less than average risk takers. I would say don’t hold your bitcoins if you are not confident about it, there is no point of investing without having faith. Bitcoin is a revolutionary technology and has great potential and thus I am very interested to be a part of it from the beginning but that’s my opinion and I can’t force it on someone else.
