So, you have to live in icland for 7 years and right after that you can start to trade on isx.is!)
You can also just come here in 1-2 years and have money to spend! How about paying for your hotel, flight, and all restaurants in 2 years with Auroracoin.
That sounds like a very good way to use AUR and to get more of it circulating in the Icelandic economy.
Probably some other spin offs too, such as a possible increase in tourism and other/additional money spent.
