*Much easier to stop, much harder to track. A bank doesn't have a publicly auditable ledger the way crypto does, it can only be traced with the assent of the bank and their policies vary.
Yes because we see so much value from a public auditable log. It’s much easier to send crypto to a mixer and conceal origin/destination and much easier for the average Joe to do it.
The very origin of funds being from a mixer taints it.
