I guess you friend was lucky to make such amount of money consistently for 2 months. there are people who are actually lucky on such platforms but majority always lose at the end of the day.There is an investment one of my friends participated and he was able to make between 10 to 15% of his investment everyday for almost two months before the platform eventually crash . That's the highest I've seen on this spaces. I have also seen some platform that gives people 50% of investment and crashes the next day.
