Here is a thought about their model...

Everybody is assuming their are not actually mining...

Average ROI time people is claiming to get is around 20 weeks that means (with round numbers) that youre getting a 5% of your investment back every week.

If they lend your money at some margin trading website they can get a 2.5% out of it every week...

So after 5 months you will have your money back and the will earn a 30% ... yes, the still will have to pay you some pocket money for the next 4 and a half years.... but did you hear of anyone getting a 30% profit here?

Its sustainable? probably... risky? yes... but getting a 30% out of other people investment... definetely sound like a good business to me...

And btw, I have some money put there and in other websites, but I will not damage my credibility posting referral links
