Actually we did not know what is fair or not because we did not see the system behind, but I'm pretty much sure that they did not lose the owner of the gambling sites because it is a system already that they input only the players is possible to lose and to win but for them are not.
You can know which is fair and which is not.
There's provably fair for most dice sites and you can verify it. But if you're not confident knowing it, just go with the flow and the crowd where they are mostly playing dice.
A crowd that's legitimate and not just a bunch of shills that are directing you where to play.
