Pyramid \Pyr"a*mid\, n. [L. pyramis, -idis, fr. Gr. ?, ?, of
Egyptian origin: cf. F. pyramide.]
[1913 Webster]

polygonal base, and terminating in a point at the top;

4. (Finance) a fraudulent investment scheme in which the
manager promises high profits, but instead of investing
the money in a genuine profit-making activity, uses the
money from later investors to pay the profits to earlier
investors; -- also called {pyramid scheme} or {pyramid
operation}. This process inevitably collapses when
insufficient new investors are available, leaving the
later investors with total or near-total losses of their
investments. The managers usually blame government
regulations or interference for the collapse of the
scheme, rather than admit fraud.
[PJC]
