Nice article. I also think, that we are more decentralized than what it used to be like. You could have a "bad actor" which controls a lot of hash power, but what I think is even worse, is when a "bad governement" controls a lot of actors. If all the hardware accumulates in one place because electricity is cheap and the temperatures shorten the need for cooling, ultimately countries like Iceland will have a lot more of economic influence, which is really interesting.
