      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.

      And to all the inevitable "but decentralized but instant but global but whatever" repliers: if you think any of those require and are worth a NINE ORDER OF MAGNITUDE overhead, please never be an engineer.

      Pi is unfair analogy. Traditional banking system uses more power, higher fees and slower (weeks for a global transfer), and centralization is almost always objectively bad. Bitcoin also represents the absolute worst tech of any coin available.

      Traditional banking wastes *nowhere near* the amount of power per transaction that Bitcoin does - that's obvious to anyone. At normal eletricity prices (i.e. what banks would have), a transaction would cost $33 with Bitcoin level overhead. Which they don't.

      I was referring to the overall power usage of each system. Traditional banking is extremely inefficient and not an engineering feat. Cryptocurrency solves a number of real problems, it's opinion if they are relevant or not.

      My point is that traditional banking, as huge and bloated and unoptimized as it is, is still *much* more efficient than Bitcoin, per transaction. Of course we can and should design a system that can actually implement distributed transactions efficiently.

          Check out the $ardor project. Proof of Stake can be the real future for cryptocurrencies. Even a Raspberry pi powered by a solar panel it's enough to actively secure the network. Bitcoin it's the first, not the better.

          It's also worth noting much of the energy traditional banking consumes is from paid human labor which, while not a highly efficient system, is supposed to be the whole point of socioeconomics..

          We're comparing two inefficienct systems, it is correct to point out these jobs are better suited for machines. Both will evolve.
