Hi Doug, thanks for your comment. Long time no see.

Personally I consider BTC mining as irrelevant considering it uses excess energy since it skims off the cheapest energy of the planet. Which will be more and more wind, solar and geothermal energy. We have an abundance of green energy "locally". What we lack is energy that can be transported. And that is always more costly, thus not interesting for miners.

I don't know if I would call myself an ecologists. I know that I tend to invest the profits I make into buying land, and transforming it into permaculture projects. I envision a techno ecological utopia with people living in rural areas while connected on the internet. But, for example, I support both Nuclear energy and DIY DNA hacking. Something which ecologists would probably crucify me for.

The problem with sanctions is that it is manipulating the market. And a manipulated market is less efficient. Among other things it makes it profitable to use oil in Venezuela (or Natural Gas in Siberia) to mine bitcoin. And THAT is pollution and carbon in the atmosphere we could do without.
