This is not a giveaway... you want people to pay .1 BTC in order to get a ticket. They will then have a 10% chance of winning 1 BTC, correct? Anyone could make this bet at one of the million dice sites out there, so I can only assume you want to scam.
No I don't want to scam and I can prove that I wont be using another account to get the 1 btc.
