I haven't read the Twitter link you posted but the other sources I have read say that the Bhutan government mined this bitcoin rather than having bought it.  Which I think is bigger news.  I f true this would make them only the second country after El Salvador that I'm aware of that are mining Bitcoin at a national level.  From the little I know about Bhutan it seems like they are a pretty unique country, I would be interested to hear of any first hand experiences from people here.
