I did get the hint of Scandinavia with your posting name.
I do trade rather large amounts of GBP and USD currencies and deposit in these two but that is because they are my spending money wherever I travel and live, but I think both will get hammered at some time soon.
Aussie Dollar has had a good showing last year or part of it but I can't take the exchange risk with your two favoured currencies, thanks for sharing the info though.
