Interesting. This doesn't make sense to me though because I thought part of the reason so much mining was happening in China is miners were taking advantage of electricity subsidies.

Edit: This suggests that they are likely using VPNs and mining pools to do it.

> Although Beijing exiled its crypto miners in May and then doubled down on its mining ban in September and again in November, multiple sources tell CNBC that as much as 20% of all the world’s bitcoin miners remain in China.

Still, "most mining", has definitely been stopped.

I was also very surprised to see it drop to 0% in that chart too, especially considering I saw an article a few days ago that China vowed to hunt down and stop all bitcoin miners in their country within a year, but I didn't see any other data to suggest otherwise.

So yeah, I believe that article that there could still be 20% of mining hiding somewhere within China and using VPNs.

But it definitely resulted in a big shift away from China, regardless.
