What you say doesn't surprise me at all: sounds like Japan are way ahead of the regulation game compared to what's going on here in the UK: it's as if the government's never even heard of it?!

So don't get too depressed... I mean, can you name me one disruptive innovation in history that hasn't been co-opted by the mainstream? (Don't worry if you can't, I don't think there are any!)

In terms of whose buying into it, most people aren't anarchists, regulation and co-optation of some cryptos might be a good thing for the overall price (and come on, the state's welcome to Bitcoin - it's a dinosaur!) , but given the sheer amount of different alt-coins out there, there's still plenty of opportunity for anonymity and stateless transactions going forwards.
