From the arguement posted. I can see no one deny it is a pyramid scheme.

Pyramid scheme survival is relied on the followers, Swisscash can last that long because there is still got followers joining. Basically it is a 'passing game', early bird feed on the followers. If there is no or not sufficient followers to feed the early bird then the scheme will collapse, so the last or latest followers lose all and the 'tauke' grab the most while early birds get some sweet from it.

Final conclusion, it is a pyramid scheme. That's all. I don't think it is worth to argue that so much.
