I remember one particular casino which had some affiliate program for example, and as it is their own casino, they changed the affiliate return, it's their casino after all why shouldn't they be capable of changing it, hell Binance even did that, back in the early days it was 50%, now it's very little. But in the end, affiliate marketers ended up even neg tagging them for lowering it, so this will be a risk for blackjack.fun too when they eventually change it, if they even change it.
