I know that in casinos, there’s not much difference between rates of winning because it’s random but hypothetically which one is more important for you? Profit or Privacy?
In this case I would choose the most profitable one, considering it would be possible to make consistent profit from it the more I played. We know it's impossible, but since it's an hypothetical question, that is what I would go for without any doubts... And even if I lived in a country where gambling was banned, then I would have a very good reason to move myself to another country where I could gamble without worries, while still making profit for a living.
