Interesting article. Thank you for posting.

Some ideas about this: We have to consider that those information mean that Bitcoin Mining can really be eco-friendly.
We can use energy for heating and, at the same time, for crypto mining. Simply, the energy produced in mining is converted in heat (obviously) and - this is the point- the heart is used in recycled for heating houses. This is a very cool way to optimize energy-consumption processes.

Of course, we have to consider that for mining you use green energy or some energy surplus by traditional sources - so the eco-disaster is still a not-near possibility, because there is none clear effect on world energy production obtained by using traditional sources
