Ministry of Finance has the final authority for money and financial matters. Have a look at USA China trade war where Donald Trump has put $150 billion tariffs on Chinese imports.
Looks like China is the next to ban Bitcoin
China has banned & unbanned bitcoin about 10 times
only one thing i can see this problem about crypto currency banning of some country because want to regulate crypto's after banning they came accepting again because government realize big profits lose from their financial stability, why i say this because my point is crypto's giving good job and good earnings to the unemployed people working in virtual currency in the good ways specially in world of trading online exchange and mining.
