I would love to see these researches honestly. I do not believe that only 1.6% of traders make a profit, I think there must be a lot more people who make a profit from trading. After sharing something like this, it is obviously important to provide the stats data and where you found this information.

If you could provide the information from the research that shows that only 1.6% traders make a profit, I would have to say the reason is probably only 1.6% of traders keep trading with any emotions after a long period, many people trade because they want to get rich, and they see wall street type of people getting very rich and they want to do the same but they forget that those people deal in billions and they make very low sums of profit but do it for decades instead of few months.
