I believe that it will come true very soon. Some banks are doing work.They will soon know bitcoin.
i think bitcoin do not need bank because bank has a lot of charges and tax i think bitcoin is better on their own position because currently bitcoin have too much lowest fees so bitcoin do not need any bank. Actually there are banks that accepts bitcoin, for example is in Japan, Japan is using bitcoin as a currency in their country see it here https://www.cryptocoinsnews.com/japan-accepts-bitcoin-as-legal-payment-method-whats-next and also in the Philippines, https://bravenewcoin.com/news/the-philippines-central-bank-approves-new-bitcoin-exchange-regulation.
And the next thing we will know, is the banks all over the world will accepts bitcoin, and also the all the people in this whole wide world.
