Certainly anything higher than 30 percent is unrealistic and shows sign of a red flag. One thing common with forex trading is Young trader opening mini shop and claiming to offer some percentage of interest which they might not be able to attain at the end.yes I've heard of it before but I didn't invested in it because my mind was even doubting the authenticity of most of this thing ,now i have come to find out that if a platform does not offer below 30% return on invested capital I'll never make a single investment with them because they are scam.
