If you say just one or some banks maybe yes. but if you say entirely bank in the world would disappear because of btc I think it is not possible
some country even forbide the circulation of btc. how can bitcoin affect the bank in that country

Bank small banks can indeed disappear but big banks will never disappear, especially because bitcoin. Banks have the economic strength of a country, so the bank has an important role. Banks will continue to have updates so it will continue to follow the development of the era. Progress bitcoin later will not affect the bank.
