The Great Mining Migration

China's Cryptocurrency Crackdown has been dramatically effective. The total hashrate dropped by over a half from its peak before recovering. As I write it is still down about 15% from the peak.

The latest figures from the Cambridge Bitcoin Energy Consumption Index provide more detail on what happened. In May China was producing 70.9 Exahash/sec and 44% of the total, as against 75% in 2019. In July, it produced none, triggering the collapse in the hash rate.

The gradual recovery happened as the containers of mining rigs reached their destinations, which by August were mostly in the US (42.7 Exahash/sec), Kazakhstan (21.9 Exahash/sec) and Canada (11.5 Exhash/sec).

If the migration continues to favor the US and Canada, which as of August accounted for about 45% of the total, it would bring closer the ability of Western nations to turn off Bitcoin, as outlined in Unstoppable Code?.

Bloomberg's Hundreds of Banned Crypto Miners Were Siphoning Power at China’s State Firms reveals:

"Zhejiang and Jiangsu provinces recently started targeting miners who were consuming the resources of state-owned enterprises, government agencies, and universities and research institutes, according to a government statement and media reports that did not name the entities.

Jiangsu found about one-fifth of some 4,500 internet protocol addresses associated with illegal mining activity belonged to public institutions, according to the media outlet The Paper, which cited provincial communications authorities. Some 260,000 kilowatt hours of electricity were being used per day, the newspaper added."
