Also how dooglus could rig the game (but it would be super easy to spot): adjust the max bet to a lower value as soon as a (according to the previous settings) win is coming up.
Yes, that was a concern that was raised before the site launched. As it turns out, the maximum bet is so high that nobody ever gets close to it, and reducing it to a level where it would affect anyone would be super obvious.
For casinos with a smaller bankroll however, that would be a viable way of cheating.
