When I first read this explanation in the OlympusDAO documentation, I laughed and laughed. “Well yes right,” I thought, “the way a Ponzi scheme works is that early ‘investors’ get rich as long as later investors keep buying more.” Sure, (3, 3). “If we all keep buying this thing its price will go up and we will be rich” is absolutely the main financial theme of 2021, but it is an irreducibly silly theme and I would be embarrassed to formalize it with game theory.
