has become human nature, always wants more than we can achieve but sometimes things like that can destroy us in an instant, especially for bitcoin trading, sometimes we don't want to get a little profit, especially seeing good trends, we always fall asleep because we always delay sales if it is considered unfavorable, but we can get the losses we sometimes get.
Yes human is greedy by nature and he will remain greedy forever. Human always think about his benefit either from fair or unfair means, very few people may care about their mean of earning either he is earning from fair or unfair means.
