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.
There are so many ways to launder money, not only in a casino. A wise criminal will find the best way. Those who use a casino are I think have another purpose other than to launder money. Maybe they literally want to play a gambling? To have fun or to possibly increase the money that they deposit.
There are gambling sites which doesn't mandate a KYC and if the site blocks them upon withdrawal asking them to upload their KYC, I think they will use someone else identity. There are so many things that you can do if you have lots of money and you can easily get away with the crimes that you will be doing. This is the power of money.
Cant really deny if we do really talk about having lots of money which you could really almost do everything where you could easily bypass out because you could really able to buy services and documents if you
wanted to and this world is really that highly appreciating and wants money where everything could really be that possible.People are really that just too focused on gambling field when it comes to money laundering
without tending to look into other angle which there are really other ways to launder money.You would really be expecting for government to go in every single one of them which they would
really be dealing up with those platforms or companies which are commonly attached on it.
