Just to double down on the ESG point, as I'd welcome your take.

Let's first separate ESG, which is a loaded term, from some basic facts.

Fact 1) majority of climate scientists believe carbon emissions to be a major contributor to man made climate change.

Fact 2) Bitcoin uses a deliberately energy intensive consensus mechanism. At least 50% of that energy is not coming from renewables so is contributing to carbon emissions.

Fact 3) a relatively small % of the global financial system involves BTC

Take these together. There's no guarantee in my head that BTC scales its energy use in a common sense way. Rationally, it'll eat up exactly as much energy from fossil fuels as is profitable given block rewards, tx fees and the price, then it will source hash rates from cheaper sources.

This probably WILL mean BTC uses a decent chunk of renewables but:

a) this will only happen AFTER it exhausts power consumption at marginal cost from non renewables

b) will consequently drive up said prices

c) will likely crowd out other energy uses during bull runs, as BTC can temporarily shift back into otherwise unprofitable energy sectors.

On top of that, how exactly does this scale? We don't know. BTC secures itself with an ungodly amount of energy consumption per Tx and this is with the tiny use we have in crypto today. How do we expect this to behave if BTC replaces the global financial system?

I'm not 100% set in stone here, but I sometimes feel we're setting aside basic common sense with mental gymnastics around PoW.
