AML (anti-money laundering)
The legal framework and monitoring a casino runs so that dirty money cannot be washed through player accounts.
AML (anti-money laundering) is the mix of laws, internal policy and monitoring that keeps criminals from passing illicit funds through a business. At a gambling site that means ID checks, watching deposit and withdrawal flows, flagging odd patterns and reporting suspicious activity to the authorities.
How AML shapes the cashier
Many cashier rules players dislike come from AML duties: source-of-funds requests, holds on large withdrawals, the "same method in, same method out" rule, and terms forcing you to wager a deposit before cashing out. In the terms of service, look for them under AML or KYC.
On-chain screening
Crypto cashiers often run incoming coins through blockchain analytics. Coins that touched a mixer or a sanctioned service can end up frozen, and sending a withdrawal to an address the analytics tool flags can also create trouble.
The Canadian angle
Licensed operators in Canada, along with crypto firms registered as money services businesses, report to FINTRAC. That includes a report whenever a virtual currency transaction reaches C$10,000 or more.
Practical advice
Fund your play only from wallets and accounts held in your own name, and keep a paper trail showing where the money originated.
