You can actually deposit your money into somewhere like Localbitcoins.com, from there you will be able to sell your bitcoin to somebody who will pay you by bank transfer. This is pretty much the same as a bank withdrawal, just requiring a third party.

However, cashing out directly from BTC to Bank Transfer is not possible since they're two different platforms. Unless your bank has a built-in exchange, which I highly doubt considering most banks hate crypto.

Shoot me a PM if you need any help.
