Bhutan holds BTC. OK, but so what? Almost all the countries around the world are holding seized Bitcoins. Some small and underdeveloped countries like Bhutan and El Salvador are investing in Bitcoin, but that doesn't mean that Bitcoin will be widely accepted as an investment opportunity for most governments around the world. There's no point of writing forum posts about "Country A having X amount of Bitcoins", unless you want to boost your post count.

I would be really surprised of news about China and India investing in BTC. Nobody cares about countries like Bhutan.
I see some people getting excited and happy about this news but I really don't see anything special or worth getting excited about. These days, news of a country holding bitcoin is no longer surprising news, especially for small countries.
You are right, even if more countries openly own bitcoin it does not mean that bitcoin will be widely accepted as an investment opportunity for governments. Like the German government, they don't even care about it and are willing to sell it all at any price.
I guess many people here didn't even know Bhutan existed until this article appeared.
