Czuch: I don't see any difference at all. The chip count, as well as the BKR, determines the ranking of players. Buying a considerable amount of chips is, in my opinion, equal to buying a considerable amount of BKR points. If people are allowed to trade poker chips or BKR, the rankings will become useless. When I play the top player of a particular game, I expect that the player has proven himself to have the best results in terms of playing that game, not in trading chips or BKR for whatever else.
puupia: If there were no bugs in the system, the overall chipleader would have approx. 25000 chips, a few others would be above ten thousand and most players would not exceed five thousand. That's not what I call flooded market.
