Soon or later, a country should regulate bitcoin an exchanges due to trading volume getting bigger as time goes on.
As long as government doesn't ban bitcoin and people could trade in exchnges, even though it was stated as illegal, not to be used as medium of payment, it doesn't matter. Actually, Chinese people still have 2 biggest exchanges to trade cryptocurrency until the end of October, so the cat still in the bag.
This is one of the oldest strategies of governments as long as a business remain small then they are not going to bother with you but once the business gets big enough then governments are going to begin to hit you with all kinds of taxes to try to get what they think it belongs to them.
