Fear, greed and so on are of course bad, but sometimes you need to allow it, to a certain extent, to achieve the best result. Because if you do not want to achieve something more, you can remain with nothing.
And in addition to your statement, being impatience and don't have any self-discipline nor self-control is not also good when you are in the actual
trade platform. Because if you will allow this to be happen for sure it will lead you into loss of your coins. If you will overcome these matter for sure the end result would be good of course.
