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.
The important thing is to get AUR circulating in the Icelandic economy. If the Icelanders use it, then tourists can use it. Then it can be accepted for exports, and finally might be accepted for imports. High volume on the ISX might not really be the best indicator of AUR being used without exchanging it for ISK.
