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.
Indeed making a bank accept bitcoib is a huge step for the development of bitcoin. We all know that bank and bitcoin haveva big difference in some aspect but it may also help by the stock and holding processes. If bitcoin want total acceptance of bitcoin for the globalization legality may be a problem but ofcourse bitcoin iw decentalized so we do not want government to manipulate bitcoin because the transaction and the price/value is the best characteristic of bitcoin users reasons on supporting bitcoins development.
