Most of the sites listed do offer over 0.1% interest which is just not possible to sustain. They will run out of funds and already have because they just recycle investor's deposits back to new investors without putting any of their own funds into it. That is a typical Ponzi scheme procedure. I will not invest into any such sites as they will not give you anything just if your lucky your money back to you.
I think all the ponzi sites offering high interest are already scam's projects
we have to take care before investing there
