Mistertango does have a BTC deposit feature that is connected to their exchange (only EUR is deposited on the bank account). It conviniently allows you to deposit BTC to an address and have EUR in your bank account the moment it's sold. What I take issue with that feature is the fact that it is set to charge a minimum fee of 0.0025 BTC which these days has become too large in value due to the rise in bitcoin's price.
