With the edge reversed, then the strategy is reversed, and you can essentially use the casino's strategy against them, and become the house yourself, in a sense.
But if the house bankroll by far exceeds that of the userbase, time limits set and max bets canceled, it follows that the house may win in the end with the house edge reversed, right?
If that was the case the only thing that would happen is that it would be slower to destroy the house bankroll, it would take more time but eventually they will lose everything, at least in theory since they have max bets they cant win much money either so the house bankroll doesnt change much if someone loses
