Absolutely, to a rational investor, this is the crucial information. How does a "CASH" trust make way more than FD rate or money market fund rate?

The entity make no explanation or disclosure of any sorts on how do they make money to pay this higher than usual returns to the investors. That is what irks me

Anyway, people who go for it are people who aren't interested about the mechanics. They are interested of the return rate promised; and whether people have been getting the returns as promised. But then, that's how money game is played isn't it?
