What I don't understand about the anti money laundering policies of these crypto casinos is that they say if you deposit BTC you have to gamble it before withdrawing, which is a policy I understand having, but how does that stop money laundering? Every casino has low risk games you can play without losing a lot of money. I guess if you have a ton of money it might be an issue spending so much time gambling it all, but for most people I don't see how this deters money laundering. As long as it works and makes regulators happy I guess...
Well you are not the only one asking this particular question but I came to conclusion that someone wants to use the casino for money laundering and funded the casino which huge amount of money the rate of which he will be task to gamble first before he withdraw will be higher and possible chance of the whole thing going sideways because I know some casino have a rule of wagering the actual amount deposit for a couple of times.
You are right, many casino will not allow their customers to deposit into their casino account and withdraw as soon as possible, so the casino will ask the person to wager two times or more times before he or she could be able to withdraw. However, the chances of winning is very little (as you have said) because if the gambler that wants to use the casino to launder money was lucky to win up to two times, the third time might not be successful. Although even though the gambler was lucky on all his attempts, the casino will probably ask him/her to verify KYC first before making any withdrawals.. And I believed that every reputable casino will report any suspectius customers to the (FIU) Financial Intelligent Unit.
