Reminder that the same applies to use of crypto. Just because it's use for some illegal activity (it's actually less % than fiat), doesn't mean it should be made illegal as I've seen some comments here advocating for in the past.
If you mean cryptocurrency, then that's wrong, because its primary purpose is to facilitate illegal activity, or grifting. It isn't even good as money, and I still can't buy groceries with Bitcoin, which is like... one of the things money needs to do (buy food).
You're taking the term cryptocurrency too literally
