So this is still in beta phase? I think it is not good to accept deposits while you are on beta phase as there might be unknown bug that may break down your bankroll or may give experience for the players.
Minimum bet is 0.001 ETH? Dont you think it is a little bit too high because most other sites with roulette games allow players to bet as low as 1 satoshi bitcoin. I think you should consider to reduce the min bet.
Adding faucet is not bad idea IMO or at least give one time bonus for new players to test the site aside the 5ETH fake balance.
