Hard to prove how many people actually stayed in the hotel would be my guess. Other businesses like restaurants have inventory so you can't as easily make it look like you made a great deal more money than you actually did.

This idea is really seductive. Wouldn't it be kind of hard/traceable to fake bookings though? It seems like strip clubs or some sort of service company would be better.

Say you run a hotel at 60% occupancy. Then the hotel suddenly goes to 80% occupancy. No additional costs. No inventory paper trail. A small motel with paper bookings could probably launder a lot of money for a silent partner.

10k comes in as bitcoin bookings (2-3 rooms per night). 10k-laundry fee gets paid as dividends to an "investor," "consultant" or anything really. The reservation books are paper.

Many consumer facing service businesses fit the bill, but hotels are a nice big category. It makes sense for them to be accepting internet payments.
