I am one of those early Bitcoin adopters who was turned off by energy consumption. Crypto is cool in a theoretical sense but ugly in practical sense. I mined a bit of BTC in 2011 and LTC in 2013 but when my colleagues started buying ASICs in 2017 boom I could not in good faith join them because of energy concerns. (incidentally buying ASICs is a losing proposition unless you get early access) The problem is that if BTC goes to say 500k the incentives for power (ab)use get even more perverse. POW is just like Adtech and HFT. Some Adtech and some HFT might be okay but at some point it becomes an arms race no one can win.
