Porn principle
"All of my professional service providers keep asking me about crypto because they keep hearing about it and they know I'm a tech person..."
If they like exclusive porn, they can buy some nasty stuff on the deepweb. Porn already embraced cryptocurrency.
If the old folks like the defense sector, Tell them they can finance abroad operations with almost total anonymity.
If they like controlled drugs, they can buy all of them and receive in vacuum-sealed packages by mail.
If they like security software, there are hackers for hire via cryptocurrency.
Oh, they can also donate to wikileaks or EFF.
