“The survey findings estimate that on average 39 per cent of proof-of-work mining is powered by renewable energy”

Those are the words from your source which I took some time to look at.

None of their source data, or their geographic location is presented, as are none of the actual sources.

So it is only slightly more valuable than some poor mainstream rag trying to incite hatred against one party or another to make some profit, I would say.

The part remaining which would devalue it to that level completely; deciding which party to hate, if that happens to be our inclination whenever in doubt or under scrutiny, that part is mercifully left up to the reader.

Which is where I see your prognosis fitting in.

It is quite an impressive demonstration of how to get from mildly hating on Bitcoin, to mercilessly hating on China, with no logical path connecting either evident at all, as far as I can see.

Here is some logic, in case you might recognise logic, rather than yet more hating when you see it;

Sunlight is free, extraterrestrial, and firsthand, from the only source of all energy, therefore it is the only one which really is free.

It is profit which drives the business of Bitcoin mining.

There is lot of competition amongst miners, only those with the best business case can win.

The business of Bitcoin mining is so large that its demand for graphical processing chips from companies including Nvidia, outweighs the demand from gamers, Nvidia’s original main target market.

My gaming PC contains a single Nvidia graphic processing chip, and consumes 700 watts when fully loaded in a game, the same amount of power as my lounge heater.

Mining rigs can contain hundreds, or thousands of graphical processing chips, on demand, fully loaded, 24/7.

So the industry of mining uses an awful lot of power.

The amount of work needed to compute Bitcoin continues to increase with time.

So miners have no option but to use solar, since that is the only one which is free, and to keep growing it.

More free power, and more powerful graphical chips, is their ongoing demand, for more profit.

With that logic, I find it difficult to imagine any miners at all using anything but solar.

Hence part of the reason why I don’t follow your argument.

To tell you the whole part would take me days to write here.
