FWIW, I'm a cryptocurrency skeptic, and generally pessimistic about where the world economy is heading for the next decade. I assume crypto's popularity, like the US housing market, is largely an artifact of low interest rates and massive government deficit spending, which I also assume will run into some limits, in the next few years... In other words, I expect crypto to crash hard, and languish for at least a decade. If it does return, it'll be fully co-opted & tamed by governments and Big Finance. So I believe that the carbon footprint issue will resolve itself, relatively soon. I really do hope I'm wrong about where the world economy is heading. It's honestly got me feeling pretty terrified.
