If you are balance then your not greedy because this situation will make you excess on something you want ao there's nothing good on being greedy since it will follow a huge risk for losing something to you. Maybe your right on what you say balance since we really need that to avoid getting huge losses and will not expect on something almost impossible to come.
No, I mean when we want profit, isn't that greed? but still within reasonable limits if we set realistic profit targets from how much capital we spend and also in which coins we invest. The greed that must be avoided is unrealistic greed, for example we set unreasonable targets, such as 1000x on a coin where the potential is not big, even with not much capital at all. We can actually avoid things like this very easily if we have a lot of knowledge.
