But you just outlined use cases for crypto (illicit activity, etc) in your grandparent post while simultaneously claiming crypto can't be used as a currency. Which is it?

Both.

As I said, they aren't useful at all in the real world legally, only on unregulated exchanges where only mostly criminals are able to swap their tokens for fiat from their scores of ransomware raids and scams.

I would be in favour of regulations needing to kill this part off as Monero and Zcash isn't accepted on most of them. Not to mention you cannot even pay your taxes with these crypto tokens.

It's quite easy to be ,,just'' a criminal nowdays. All you need is just be born in a country led by a multibillionaire dictator who wants to nuke the world and want to receive your salary for your hard work from an American company.
