I should have been more careful in my wording here. What I meant by this is the total energy expenditure of current payment systems (Credit cards, PayPal, WeChat Pay, Alipay, SWIFT, ACH, SEPA) including the overhead of fraud detection, chargebacks and the cost of fees on the economy. To be entirely fair you would also factor in the cost of QE & inflation. Although cryptocurrency isn’t widely used as such, notarization and its associated costs could also be taken into account. All of these factors are obviously extremely difficult to estimate properly. I still stand by my assertion that a mature cryptocurrency would be less costly for the global economy than the current systems of regional central banking and the damaging credit & debt cycles it brings with it.
