I could beat my self that I bet on this site dispite the full anonymity of the sites owner. The only contact is a bitmessage address, wich is inactive. I've lost a fair amount of money to this possible scam. The following transactions clearly won given the trade logs of the individual exchanges at the time:

445b4932e1ee35217f4bb2928e0c58663388296b59f04b33ea2178f3278d1c86

Trade logs show that the exchange rate was not even close to the outcome value. And it is quite remarkable that the "result" in all cases is very very close to the start value. I would love to see wich individual trades where responsible for the outcome. Or otherwise a refund. Cny/usd exchange rate is 6.144 right now.
