Well, you will never see or hear it from the statement of investors. Besides, there is no urge for a trader to flex their income in order to prove that they are earning a lot. Some are just quiet and want to hide their income and losses. You will only hear it if you ask them personally, just like I did to some of my friends who are traders. They admit that not all the time they are profitable. They lost somehow because of the unpredictable movement of the price. And they tell me that they only make good profits during the bull season and suffer difficulties during the bear months.
