Honestly, it's my first time to hear about a country without a national currency. If so then I wonder, how can they manage transactions in daily lives? Do they used only exchange of goods and precious assets (e.g. Food, gold etc.) or any different currency?

Anyway, I'm glad that they are now embracing bitcoin. This is a good start for empowering their economy. I just hope that their government will make a regulation regarding this to prevent abusive conducts.
