Hello Fxpulse,
I have several accounts with managed forex companies, the oldest is since 2006 and the minimum yield was 0,28%/month, they never went lower. Average ROI is around 30% p.a. They have fund, one part of the money is being traded with contango and they make obligations for 3 months for futures, and if you want to end your contract early they charge you 30% of the principal. The rest is traded daily / spot fx, they use max. 3% per trade, and they have 90 traders of which 60 are trading daily 30 are on call, every 2 days the 30 traders with the lowest performance are changed with the ones on reserve. If you don't want to use their managed account they offer individual investment, you get LPOA, ROI is lower around 25% p.a., but you have no exit fee and you can leave anytime... There are many account managers that charge fees.
I don't know about secureinvestment.com that's why I have to check it and find out, because if they are scamming we have to put out this information, but it can be possible to make such amount as they say. I personally know one trader and he makes around 100-300% p.a., but I will never invest with him, because he risks too much and doesn't make any promises and he won't trade with small money. I'm more conservative and always look for something that is somehow protected.
