I wasn't talking about buy/sell BTC. I am talking about working a regular job and be paid in BTC. That is not "bitcoin related activity". If you have auto repair shop and I work for you doing repairs, we agree each others to be paid in BTC. Is not anybody's else business how you are paying me for the job we agree upon. You can pay me also in car wheels or pink shells if I accept them. But is nobody's business why I do accept them.
