Holding was not a greedy behavior. People hold because they want to get more profit and they believe that it will be worth it in the end as what we see in the change of its value every seconds. Holding is a form of investment were people get more money from it as the value of it continue increasing. Holding also was a strategy of a person on how he/she will handle his/her bitcoin.
