There are no banks who accept bitcoin, but with the majority of banks you can withdraw money to an exchange and buy bitcoin.
I use kraken and when i want to buy bitcoins i just iniatiate a SEPA transfer and voila i can buy bitcoin.
Indeed. There is still no bank who accepts bitcoin as a deposit of their client. In addition to that, I guess that if theres a bank who totally accept bitcoin I think they cant handle it fully because the price is always change. Lastly, I hope in the near future there will be bank who totally accepts bitcoin as a deposit of their client.
