Re: Coinroll.it - Dice rolling game | Instant bets | Off-the-chain | 1% House edge
Actually, if it was me, I wouldn't be giving away 100 BTC as a promotion in the first place, 'cos it's always going to be overrun with scammers.
How about a new 10 BTC Just-Dice.com raffle for this year?
Or Mastercoin raffle, then it would be a little bit more trickier for scammers.
