I'm mostly aiming to hold on to the coins for years - so not planning to swap them back and forth a lot.. however, I'm concerned with the fee's that goes with everything..
I thought originally the strong suit of Cryptocurrency was to avoid fees - but it seems they are all over the place.. fee for converting my nkr into eur so I can get money into the exchange, fee from the exchange for putting money onto their system, transaction fees per transaction, then a new transaction fee and additional fee to transfer the coins out of the exchange onto my private wallet. then the same loop again backwards to try to get the bitcoins sold then sent back to my bank account in nkr.

Is there any exchanges that is known to be kind on the fees and not have high % fees on any of these things?  a low set fee per transmission I can live with.
Also - is there a list of which exchanges "locks" the coins until fiat-money payment has been confirmed by the end selling the coins?
