i don't think this is a greedy behavior because some of people want to hold it until another folk coming
and some people is a true fans in bitcoin ,
Bitcoin is an asset for me, that I don't want to lose it without any profit I can get from it. We, users are all here because of profit. We have our own strategy. (Though I don't have bitcoin to hold for now, )If I ever I have, that's I will do, especially this days that bitcoin is crashing. And I don't think that holding bitcoin makes me greedy because I'm just being practical and smart.
