I mean cash is better for strictly better for illegal activities. That misconception has stuck and just stays there. One leaves way to many crumps with non-private digital assets. And private ones are treated like the plague.
Plus KYC and compliance checks for any exchange in the USA and EU (dunno about the rest of the world) practically bans anything iffy.
Compliance requirements have been stricter in Coinbase from my point of view than my banks...
And my comment: Piracy and kidnapping of property existed long before cryptocurrency -- just google Somalian pirates. I don't have to reason about person kidnapping I assume.

P.S. Downvoting because you disagree with a comment that addresses another comment is not really polite.
But this is hopefully a much smaller market than the current one.
