It's very early to talk about governments adopting bitcoin.
Not making it illegal is a win right now.
Yeah and its hard to predict what will happen besides the government of every country they don't know how to put a proper regulations, taxes and not all the people want to used bitcoin or other crypto currencies, So the government don't know what is the best thing to do.
Some government really don't care for it, some really wants it and other government don't know what to do and how they are going to treat cryptocurrency, yes in the first thinking you'll think that bitcoin was a big scam but if you'll just look like the advantage of it you'll finally love it.
