The amount of revenue coming to banks as a result of exchange activities from bitcoin to fiat and vice versa cannot be under estimated and I think thats what the bank in Norway is trying to exploit taking into consideration the dicey nature of the law around there and that is why they are not selling directly so they refer you just like they would refer any of their customer to any entrepreneur who has agreed to work with the bank without them being responsible but hopefully things will get sorted and there wont be for any unnecessary intermediaries.
