there are very few secured investments out there. they are usually CDs and standard savings account that pay like 3% to 6% a year. Which is unlike this secured investment contract
i would personally be leary of anyone offering a secured investment with a 187% rate of return.
if you do decide to invest, go into knowing that you could be losing all of what you invest and never see a penny back. if you are ok with that, then go for it. if not, then i wouldn't.
also, what do they do with this money that you are giving them? are they hedge fund traders? day traders? that is a good question to ask if you do invest. if you don't like what they are doing with it, then don't invest either.
