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?
As almost every casino has KYC system where kyc is required when someone invests huge money or wins huge amount. In that case I don't think a crypto casino can be a big cause of money laundering. Because if someone is doing money laundering there then his identity will be revealed due to KYC so I don't think anyone will choose crypto casino as a money laundering route.
KYC can prevent money laundering cases, but money launderers are smart enough to move their funds from one place to another and know how much money they can spend in one place. Of course, they are so experienced in money laundering that it can make it difficult for casinos and other places of business to trace the source of that person's funds.
If there are customers who often play at the casino and spend very large sums of money and have a close relationship with the casino owner, it will make it easier for them to launder their money there because the casino owner will not suspect them.
Of course, technologies to track these money launderers are still improving throughout each year because these guys are also getting smarter each and every year. Experience help them to evolve and evade the new technologies. Other than that, casinos and authorities are already tired in chasing these guys because they knew that money launderers keeps on outsmarting them, they are just patiently waiting for some mistakes that will reveal these guys in what they are doing before making a move.
