ELI5: How do people money launder through bitcoins? Don't you have to put cash in your bank to buy bitcoins? And even if that works, then when you withdrawal money from bitcoins to buy stuff isn't doesn't that raise red flags?

I don't have a ton of experience with Bitcoin, but AFAIK, you can download a wallet app, meet with someone and exchange cash for Bitcoin (you pay cash, then simply transfer the bitcoin to your wallet by snapping an image of their QR code), and walk away. You completely bypass any bank, that's the entire point of Bitcoin.

Paying for things with Bitcoin is the same way.. just like paying with cash, basically. There is no central bank to monitor what you're doing.
