I find the responses here interesting. It sounds like you all are saying money is not energy. Not really even a question about bitcoin. I agree with you there. It isn't. He may be overstating his idea/explanation.

It has been helpful for me to think about my life/time. You could use the term "life-force" as something. I'm not sure its energy technically but we don't really have a term for it. I spend that on work. I get something in return. Dollars. Thinking about money as a battery has been a useful thought experiment to help shift my thinking. This idea has been useful for me whether or not it is technically accurate to classify money as energy.
