I had often wondered if Satoshi Dice was creating their own transactions in order to shift the odds in their favor, yet make the payouts appear statistically better. I don't see why OKcoin couldn't be engaging in similar behavior. But I will say this, the Free Market doesn't take kindly to cheaters once exposed. Decentralized exchanges will soon solve this problem if it is in fact happening.
I agree....
Anytime in a free market, people are taking advantage, they are quickly ousted and their business dissolves.....
