It came from an art sale… you can go read an article about it in the news, in fact, and sure you may think it’s ridiculous but that’s just because you’re uncultured and don’t understand Fine Art. People are demonstrably willing to pay millions for bananas on walls.
Obviously it attracts some attention (we’re here talking about it), but a whole lot less than a wire transfer of $10MM out of the country which would trigger SARs at several levels.
Ah so why do the sale at all then? Why not just deposit $10MM in cash at the bank and say it was from an art sale? Something is missing in your explanation.
How does the sale take place? Cash? So when the seller deposits the cash, no one asks where it came from?
