      Bitcoin consumes 4,000,000,000 W of power to process four transactions per second. A single Raspberry Pi with a database can do an order of magnitude more on 5W. Think about that next time you wonder if it's a good design.

      How much power do you think our entire global banking system consumes, conversions of hours and miles and so forth taken into consideration? Yes, as a species we spend enormous energy on transactions. Quantification is great, but doesn't change our nature.

      At current Bitcoin energy-guzzling levels, transactions cost $33 worth of electricity with normal electricity pricing (as banks would get). Which they obviously don't with traditional banking. Therefore traditional banking is more efficient than Bitcoin.

      Feel free to actually do the math and show me exactly how I'm wrong.

      That's exactly the point. You cannot do the exact math on either side.

      Thankfully, the math can be off by a couple orders of magnitude and the conclusion is still valid: Bitcoin is a hopelessly broken design that fundamentally does not scale.

      How exactly are you doing the math on traditional economy? Im seeing *no* numbers at all!

      You don't need to do any math to know that bank transfers and similar "traditional" mechanisms of value exchange do not have a marginal cost anywhere near $30. Otherwise banks would be bleeding cash by completing many transactions for pennies if not for free.
