Thank you for the link. These stats look interesting but they are quite old...I think we cannot simply throw numbers without specifying the group of people they relevant 😄 It's interesting to see how much of the well prepared new traders actually become successful, excluding the hazardous majority that take trading like going to casino.
I agree with the advices above. In my early steps in trading I used to get attracted by such bonus promotions and wiped my account completely, then the broker never accepts any liability in such cases. The broker is covered but you are not. So be careful as such flashy things are not as good as they seem.
