When you say something like this, do you mean you need someone to submit KYC for you or produce documents to prove where your money came from?

You may never see those services here.
If it's a reputable casino asking those KYC I guess it's safe to do it. Just come clean

But depends on how much you have in your account but seeing the term you use is "WEALTH" looks like your loaded.

If you read my message carefully, it clearly says that I need help/advice on how to act better. Not that I need documents.
KYC and source of wealth (SOW) are two different things. Before speaking, inform yourself. It is not me who uses the term wealth, but it is the name of this document.
