Greed is of major concern in trading and other businesses as a whole. When it comes to trading I think having a stop-loss is going to be helpful in this regard. We need to have a target that when it gets to our target easily pull out but then even after getting to our target greed comes into play especially when we see that the coin we invested in is still flying high. Some would then decide to continue instead of taking profit and they end up going below their capital. This calls for discipline. Set limits, set rules for the risk you take and try to stick to them.Greed most times doesn't pay even though sometimes we might just be fortunate.
