I think that if two or more people earn according to one effective strategy, then most likely this will be monitored and the chance to earn decreases, although this is my guess.
Luckily it's not how this game works. All outcomes are already pre-generated, aka all games have already happened, players just don't know the outcomes. So there is no possibility to affect the game in any way for them (casino, operator, illuminates or any other known and unknown organization). Or actually there is a way, of course, it will just be immediately spotted by players and easy to prove that they are cheating.Unless you bet insane amounts of money and can reach a max profit of 64.44 BTC (at the time of posting this) which you don't want to share with other players - I would not worry about it
