Also increasing house edge for big bet is completely laughable, even Las-Vegas would not think of doing such a thing. Why punish a high-roller for giving more action and volume? In Las-Vegas they would actually lower their edge to get those players.
Does any Vegas casino allow a player to win 1% of the casino's bankroll on a single hand?
Land casinos actually have insurance companies insure their jackpots, so it is possible to win a small percentage of the bankroll on a single roll, but the casino doesn't pay out. (is there some way you could do this? Probably best to reduce variance with lower kelly since your minimum bet size changes with kelly).
