      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.

      what BTC users are running on, they largely didn't pick as their BTC platform. it's their home computers for everything else, and just happened to also do BTC. your complaint is akin to blaming people for using MS Word to edit docs, when they could have used vim/pico.

      Nobody is mining on their home computer. Bitcoin's power consumption has nothing to do with the computers normal people run Bitcoin on.

      want to re-phrase "nobody"? Because that is absolutely wrong.

      Nope. Literally nobody (not counting any silly people doing it at a loss). It is a net waste of money to mine bitcoin on a computer. The only way to mine profitably is with ASICs and if you have cheap electricity.

          "literally nobody" ... "not counting people that do it". Yep.

          Yes, I'm sure 5 people do it for fun and losses, like anything. Doesn't change the argument.
