OP, WHAT are you talking about?
Nearly ALL COUNTRIES have banned bitcoin related bank transactions for more than four years ago (since 2013).
Bitcoin has been banned all over the world by all big banks in nearly all countries since 2013 (for over 4-years) and the banks have completely failed at stopping Bitcoin. Just try to do a bank transaction say its for "Bitcoin" and watch your transaction be blocked for review.
Everyone in all countries are still finding a way to get Bitcoins. They simply never say "Bitcoin" when dealing with banks. People are smart. Central banks directed a worldwide war on bitcoin since 2013 and have utterly failed.
They cannot stop or even slow-down Bitcoin. Adoption is actually accelerating. Nearly 1% adopted by world population and increasing. Currently, Bitcoin's total market is valued at more than $110 Billion USD.
Amazing to see global trade growth on localbitcoins as well (scroll down to see all the individual countries):
