"It is a natural step - especially since it is perceived that Bitcoin and other crypto currencies are being used to hide black money and for anti-social activities." just remove this part lol its extra, I live in California, what fiat currency was i using for my "black market" transactions? Cold hard cash. it's not a good reason to regulate cryptos or a counterlogic reason to support a pro coin argument. Yes I know people that launder quite a bit of money through cryptos, does it even come remotely close to the amount of blood money out there? nah haha dirty money clean money I don't see the difference. just to support your comment man nothing negative here.
