Hi steem-norwegia,
Most banks fear Bitcoin and cryptocurrencies, and will try to make it difficult for you to buy or sell it.
Reason is they become obsolete,as crypto don't need a bank.
More and more stores are accepting crypto, but realistically hard to live only on crypto today.
Maybe in 5-10 years we can buy all we need when needed, with crypto.

You can buy bitcoin at an Atm minibank, there is one in Oslo. Sturle at bitmynt.no is also reliable and honest.
