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%.
Thats quite haed to be part of the 10% before I tried to become a good trader, and I can tell its not really easy. Comparing the wins and loss, Id say the exchange gain more with fees than me. Its not I dont understand it but its really unpredictable. So thumbs up to those who are good into making profits on their trade.
