So If using cryptocurrencies become a crime, will you be a criminal AND use it?Note: Before you reply remember CIA/FBI/NSA/South-park/...

By mentioning those agencies I'd say yo uare speaking only about USA , even if those intelligence agencies on the whole world but there isn't much they can do if you are out their country .
Countries cannot agree on one law that make the cryptoo currencies a crime, just impossible but most likely I will keep using it yes .
