I've read it some time ago. I recalled it as less speculative than it seems now.
The premise is that energy is a large part of aluminium production cost and the plants work on small margins. An over-investment into energy production provides cheap energy and allows the aluminium plants to improve their margins via crypto mining.
Coinmint took over a very large, shut down, aluminum plant in upstate NY. This plant is powered by a dam that was built to provide power to that plant.
These dams are built in such a way that they need to continue to provide power or the equipment starts to fail.
It is also literally too expensive to build and maintain the lines to ship the power elsewhere.
Alcoa was more than happy to lease their space to someone who was going to use the power going to their facilities. There isn't much industry at this point that would fit.
All of the successful facilities that I know of (including my own) seek out cheap power... which happens to also be clean power. Hydropower. Most use existing facilities that were otherwise going to waste.
