The bad mindset of the trafers is that they always want the profit to come in their wallet as instant as possible but thats not hownit works because it needs time and efforts in order to gain a lot of money in this business. If you are lacking of patience in this thing you will never meet the expectations you ever wanted because you akways want an easy profit but nothing is easy nowadays you need to wait for the right time bedore it will get into you. And always be positive as much as possible
Usually a newbie mistake. With experience will come realization that trading isn't something that assures easy and quick money. When the losses pile up and lessons are learned, then this mentality you're talking about will be discarded for a more mature approach to trading.
