Enerique thanks for this, another very relevant article on the issues of cryptocurrency economy.

Further to the comment of Alan below, perhaps Bitcoin would get a much better image, if it could be seen as not only sustainable entirely by solar energy, which comes from off-planet, but actually money-as-sunlight, forcing up the infrastructure necessary to sustain its own expansion of value.

The only logical explanation for the precarious pursuit of volcanic energy to power Bitcoin in the sunny country of El Salvador, rather than just using established technology to set up a sustainable solar farm / hydrogen fuel cell infrastructure, is that the president there has been swayed by the capitalist agenda of controlling that energy, to sell at profit like a standard profit driven utility so as to maintain control of people.

What they might be missing with that strategy is that in the profit driven system, payment of the demands of profit require to be funded by extraction.

In other words, everyone having to struggle to pay for chargeable power has to work in the old system of money-as-debt, in many cases even having to go into debt, to pay the demands of those supplying the power.

And debt is a promise to extract, if not yet receipt of extraction.

The secret would be out, that the capital economy is no-longer zero-sum, therefore no longer even capital, if it was seen to be solar powered.
