Let's be honest, money laundering is the best thing that can happen to a casino and there is where most of high rollers comes from. I have seen some rollers in the past that runs some huge scams and then go to the casinos to play with the scammed money and with that justify where they get the money from after hitting some huge wins.
Nowadays most casinos has KYC, but i don't think that is enough to stop the money laundering, what casinos should do is to investigate the source of the deposits to fight against this illegal activity, but that will not happen because is a win-win game from them.
So, what do you say, does crypto casinos really care about money laundering?
I'm just asking you OP, I don't mean anything. You said you saw high rollers, right?
How did you say these high rollers were running some big scams, and you even knew that they played casino games to gamble with their hard-earned money? How did you know about this thing?
Second, it is also true that KYC is not enough to prevent money laundering in cryptocurrency, I think it will not be lost in the crypto business industry. Because it is anonymous, things like this will probably happen again and again for sure, But I hope it can be controlled somehow.
