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.

Seriously, what is wrong with you people. Do you truly believe it takes *five gigawatts* to run the "world's most secure and resilient financial system" that can barely handle the transaction volume of a supermarket?

The only reason Bitcoin wastes so much power is because **it is broken**. Any engineer with more than two brain cells can see that this is just a shitty design and *not* some kind of inherent cost of such a system, nor even remotely worth accepting.

You're not paying for any of Bitcoin's benefits and qualities, you're paying for the *mistakes of the designers*. Stop wasting money and contributing to carbon emissions and at least pick a slightly better altcoin or wait until one of them is shown to be a good approach.

How much power does it takes to run all the banks buildings? All the people working there taking their car? Truck taking cash to the ATMs? Machine to print those cash? Server running the Sql database? The ATMs?... Think about this before blaming a great alternative to fiat.
