Good to see someone debunking the deeply flawed Cambridge Index. "Data is currently provided by four mining pools for the latest period." [0]

There are hundreds of pools and the ones they pick have a stronger China workload. Then, they extrapolate from that limited source of data.

Given that China just turned off everything and hardware moved globally (a lot to the US), it effectively invalidates everything they have been doing.
