If 90% of traders lose their money, then 10% still manage to make a profit from trading. So this statistic is not so frightening, as everyone has a chance, having gained knowledge and experience, to become a profitable trader and become one of the most successful 10%.
Remember, these statistics are usually gathered over a small period and small typicals.
In a period of 1 year? 5 years? I doubt anybody tried going back in 5 years to ask the same people if they managed to make profit.
I can almost guarantee in the longer period of tie the 10% in profit will become 1%.
Day trading puts you even more at risk.
Be frightened
