Indeed, being able to buy BTC, ETH, as well as other altcoins and tokens at market rate directly via one's bank is very nice. The German Bitcoin.de exchange, for instance, directly cooperates with Fidor bank (German online bank) to allow direct instant trading of BTC/EUR with other "express trading" users on the Bitcoin.de platform.

It would be nice to see something along the lines of that, i.e. allowing users to deposit funds right from their bank account as quickly as possible. Needless to say -- cooperating with banks, however, is not unproblematic. Of course, not every exchange should necessarily support FIAT or be affiliated with banks. I warmly welcome a solid low fee exchange that only supports BTC and ETH trading pairs. I don't mind if it doesn't support FIAT deposit/withdrawal. If it has a smoothly working fiat implementation: good bonus.
