BTW I do not know what kind of security features you have implemented but you are being hacked right now - klaimer2685 is squeezing the juice out of your bankroll... Just saying...
So far klaimer2685 has only won .68 BTC and i see klaimer2685 bets rolling(low bets with higher payouts), the user is winning how's that a hack? he/she is lucky today! 
Yap, thats funny to see someone say a lucky player is a hacker when he win good amount by martingale with high payout. If all people has the same mind as him, then he will call all winning players as hacker. LOL.
But even if what he say is true then any sites will do another security check before releasing any funds if the site feels that there is something fishy on the bets.
Sure I can't prove it, just seems a bit strange having made 60k bets and having won 0.76 BTC
How can it be so strange for you? Look at how much he have wagered as well. He have wagered almost 6btc and only win less than 1btc.
Mathematically, with 60k bets and with 0.76 profit, he only made around 1300satoshi profit per bet. It does not strange at all.
