Mathematical Maneuver

Remember the MMM? A great demonstration of so-called "Pyramid scheme". This can be often seen in normal trades in small batches. However, MMM stands out for its huge cash flow and deep political influence. In my point of view, this is a very good mathematical maneuver of stock market. And politically, a lot of points are debatable. This is proven by the afterstory of Sergei Mavrody.
