How do banks in Norway, Sweden and denmark work with bitcoin?
As for Norway, my experience is bank don't work very well with Bitcoin. If you're lucky, they don't know what it is and don't care, otherwise they seem to be a bit on the paranoid side and prefer to not be involved.
For instance, DnB closed the bank acount of Justcoin effectively shutting down a very successful exchange in Norway.
Is it safe to trade bitcoin with bank transfers?
I myself sold some coins and was paid by bank transfers. As most people doing this, I experienced at some point one buyer initiating a (fraudulent) chargeback claiming non-delivery of coins, after which my bank (BNBank) made efforts to shut down my account (they froze it for a while and only reopened it after a lot of complaining). If you plan on selling coins and accepting deposit into your bank account, just make sure you have a paper trail of some sort in case your buyer tries to scam you (*especially* Germans!)
Is there any local prepaid card that will work with bitcoin? Like xapo or advcash?
I have no experience with prepaid cards, but I assume that pre-paid Visa/Mastercards obtained outside Scandinavia would also work within Scandinavia. The only pre-paid card provider I know of in Scandinavia is CCEDK (
www.ccedc.com) which has several posts on this sub-forum.
Good luck.
