I suggest you reduce the max bet , atleast to seem more trustable.
EG : Max winnings = 10 % of bankroll , max bet based on that.
Until you can provide proof that you have over 6 million bitcoins
100 max bet * 60thousand something odds = 6 million
If someone bets 100 and wins the min odds , they will be definitely scammed ( even if you are Satoshi )
