WARNING ... DRIFT ALERT ... WARNING
Speaking of money laundering, in my current position I have observed some not so small-scale money laundering. I service CoinStar kiosks five to six days per week. Ten kiosks per day. A full kiosk, which is very common, contains two bins of about 500# of coin each. Depending on the denomination, two full bins will have a value of between $8,500 and $14,000.
Many people make money off machines that require coin for purchases. The biggest is laundromats. Through observation of trends and talking with store managers when I'm servicing, I picked up on the trend. These people are paying for the use of the kiosk and running their coins through these. Dump your coins, the machine tallies, and you either put it in crypto, gift card, or get cash. With cash there is zero trail, and since washers and dryers don't keep record, what you report to Big Brother is what you care to report.
CoinStar also has the ability to convert cash to crypto or gift card, but that does utilize some personal information. More than once, I have observed a person doing the cash conversion, and they were punching in information that was on a piece of paper. The kiosks have a warning sign on them about not making gift card or crypto conversions for other people. Kind of like TSA warning you to not hold luggage for strangers.
