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 ,
Yes it is not being greedy, it's about grabbing the opportunity and improve it. Most people like me here are just making sure that our job will be done well. I also agree that some people use bitcoin because they are true fans of it and they think that they should keep it because they know that they will be benefited.
