It doesn't have any impact since 1 BTC still 1 BTC nothing change we can still play normally without worrying anything related to price action. But maybe for other they are counting the value since it adds up their losses if the market dump so for sure they get stress on certain condition and that could ruin their game.

So far it didn't change my gaming habits I still play according the sessions I play same as before and also I see known people do the same so for that nothing really change. But there are some factor can possibly affect since if bitcoin price pump we need to deposit more $ in value so that we can reach up to that BTC figures to use for gambling, but still depends on people since not everyone has the same mindset since this might affect those people who usually place small bets since this is the only amount they can afford.
