How much money to maintain fiat? Not just printing but all aspects of banking to secure the currency and back it?

Narrow minded views of energy consumption allow for fear tactics distract from the reality that other commodities require a shitload of energy. There are at least 77,500 bank buildings in the US right now ($350m in energy costs using conservative estimates) … Just the US and just the branches, not the corporate offices, not their servers, not the 1000s of other things needed to maintain those banks and the fiat currency itself or all the parties involved in payment processing… Now think global. Bitcoin is cheap compared to the alternative.
