How could you possibly launder money with cryptos?

I dont see any real reason to restrict players from withdrawing what they have won, other than creating problems when the company can make a big buck..
Not sure if Crashino or their group of sites applies their withdraw limits on big deposits, but what would be the reason to do so? If they suspect something, they will do the research for it, and then release the winnings, its not about the amount won, its about if you won it in a fair way.

Also, Max deposit 50 000$ and max withdraw per month 30 000$ is no big news on casino industry. There are places where you can withdraw 500$ a week but deposit 10 000$ a day.
