I've watched Nakowa gambling, and I'm obviously not 100% sure that he is not cheating, but I'm willing to bet my whole investment (which anyhow I can afford to lose) on the fact the he is NOT cheating, and thus I'd let him play with max profit 1% of the bankroll until he eventually go busto with his 300BTC bets.

And think of the publicity this is bringing to just-dice.com and bitcoin in general. I was telling everyone about this mysterious whale's, $20k, $30k, $40k+ bets, and everyone was eating it up! With the reduced max bet size, it's not nearly as sensational.
