Re the carbon footprint argument with Bitcoin:
I’m curious how the energy use of just a top 5 retail bank compares to Bitcoin.
Chase [0], for instance, has over 5,000 retail locations and 16,000 ATMs. And the servers, and call centers/corporate offices to support 200,000 employees. And the cars they drive back and forth to those offices, and the construction of new ones, and flights (some private), etc etc.
How much energy does that use—let alone the physical resources and their attendant carbon and energy use?
Then you have another 4,500 branches from Bank of America, 7200 for Wells, etc. And that’s just the US.
Not equivocating, nor arguing that Bitcoin could replace all their functions, but I think there might be more nuance to the energy argument, especially when at least other crypto currencies have an off ramp with their energy use via proof of stake.
