Nothing surprising in my opinion. USA and Europe leading the pace! Pretty much where the Internet is most advanced we see the most advancement in Bitcoin as well!
Not when it comes to market shares, which is pretty much important asset. Bitcoin exchanges are basically getting bounced up as chinese exchanges dictate, since most of the volume is coming from their direction,
as well as virtually every single hype or drop. Bitcoin nodes distribution is another thing tho, probably because there's no profit to be made there by running one of them.
