It's nice and all, but the same people who are running the biggest ransomware operations now had no trouble receiving the billions of dollars they were stealing directly from US bank accounts before they pivoted to ransomware.

Ransomware would still work just fine using regular bank transfers. Especially given that the payor has no incentive to stop that money from arriving at it's destination.

But sure, using crypto the criminals get to keep the 20-30% they'd pay for payment processing otherwise. I'm not sure that really makes a difference though.
