Wrong decision. I don't see any reason why the player should pay for your negligence. Pay the man his money.
The Community was perfectly aware that the game was in advanced test regime, the bug bounty was actively promoted in community and we beforehand stated that game might have been bug prune.
That's the whole concept of community and community development of the product basically. We put the product online and say "We are introducing you a new product and would like you to contribute to its development" and we get lots of letters on how to improve and we improve it and reward players. That was our approach here as the game was new and provably fair and we considered that community that values communal spirit and decentralized approach will appreciate the attitude, as we came from here as well. The game had a bug, yes and as we learned about the bug, we naturally seized the bug winnings, because it is impossible to determine if the winnings were made from naivety or purposeful abuse of the bug and yes its a hard decision and its a very delicate situation, but there is nothing else we can do here.

1) Does your approach include refunding amounts lost while playing games with bugs?
2) If you were aware beforehand that the game could've had bugs, then it was irresponsible on your part to allow users play with real money.
3) He did not cheat your system. If he did, his natural inclination would have been to quickly withdraw the ill gotten profit. And not hang around wagering a significant portion trying his luck elsewhere on your platform.
4) Even at that, you haven't proved conclusively that he used the bug earnings to win the jackpot. One can argue successfully that part of the .019 or so btc he wagered to win the jackpot included his deposit.
5) A serious & honest casino would negotiate a significant settlement with the player and not just award him a small bug bounty (in relation to the amount won) + fake sympathy and hope he goes away. That would be the right thing to do.
@verusfides, I'd suggest you open a scam accusation against FJ here:
