A quick search on Google reveals that there's approx. 2,195 commercial bank branches / 100,000 people. Let's just assume, that there's an equal amount of ATM machines.

I wonder what the collective energy usage of millions of bank branches and ATM's, and keeping those ATM's stocked with money, add up to?

Not to talk about the brainpower wasted on misleading customers, manipulation of markets and lobbying politicians to keep their eyes closed...

How does that compare with "crypto"?
