I think this is huge step indeed, but I would be cautious because well all know that banks don't like bitcoin because of its de-centralized features that is why you can buy directly but to use an exchange. But why used banks anyway when you can just buy it thru local coins or exchanges like coinbase that they have pointed at? Well, I think we should monitor and how see things work out with this setup in Norway.
Because some people are willing to give up privacy to win in comfort and to be able to cash out their earnings easier when they are trading, so to me it makes sense for this service to exist also banks only care about one thing earning money, so it makes sense at some point some are going to accept bitcoin.
