Doog proposed a solution: make max bet a market. You choose what your tolerance is and the site will adjust. Mech could have set his to 0.25%, I would have kept it at 1%, every investor votes with their wallet. From there you get the max bet and the proportion to be paid out to each investor.

No controversy, no arbitrarily choosing numbers. House edge can remain fixed so that from the player's point of view, nothing changes or is unfair.
