High-yield investment opportunities  Worst Moneymakers A high-
yield investment program (HYIP) is essentially just a Ponzi
scheme, a principle with which everyone and his grandma is
familiar with by now -- investors are promised an absurdly high
return, and initially they get it (or rather, they get the money
of the new investors who were promised the same thing). The
scheme is completely unsustainable after a few levels, which is
why the people who implement them rely on early investors to
spread news of their success.  HYIPs are thoroughly illegal, and
the simple rule of thumb is that any promised high return that
seems too good to be true almost certainly is.
