I believe @themarkymark's post was made to highlight how unsustainable it is if one should approach the game as a financial venture. I have full confidence that any "ponzi" element was accidental on the dev's part and now they are scrambling to fix the distribution and (more probably) the image of the game.
It's sold as a game, it did not tell you invest; but everyone 'invests' anyways, is it an investment vehicle now?
