But how is Just-dice able to set their max profit so high?
The number I see there:
Site invested: 554,737.47504713
Max profit: 136,569.72
Because most sites you risk a % of the money you invest, while Just-Dice allows you to risk a % of your total bankroll, even if only a small fraction of it is on-site. Like for most things, Dooglus has a great FAQ and full explanation if you're interested
