I believe the synagogue shooter was paid in Bitcoin. So not pure hyperbole.

Edit: might have the details confused about above point, but the general thrust of things is pretty clear. https://foreignpolicy.com/2019/03/19/neo-nazis-banked-on-bit...

Well in that case, nothing incentivizes more crime than USD.

It’s more regulated though. That’s the point is there’s some control in usd, for better and worse.

Cash is the ultimate anonymous method of payment.

Cash is a physical thing that needs to be taken somewhere if you're using it to pay someone off or receive a payoff. That gives means to be apprehended at some point in the chain. Crypto on the other hand you just hand over the coins. The coins are sent to an exchange's wallet, mingled, then pulled out on another anonymous wallet. This is what makes it so great for ransoms.

Not necessarily. Bills have serial numbers on them. They can also be marked.

Their complaint was not with your premise but the language. Rather than incentivizes perhaps facilitates.
