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.

This is so stupid and inaccurate! Take all banks buildings in the world, the energy and environmental waste created to build and maintain those buildings. All computers and servers required to maintain each bank ledgers. Then the vehicle that move fiat... #Bitcoin is green!

So you're saying instead of spending <insert large amount of energy> to perform <insert large amount of transactions> like banks do, we should spend 4 gigawatts to perform 4 transactions per second. Right. So green. Please try using your brain, this isn't complicated math.

Once Bitcoin is mainstream you won't need banks.

Bitcoin will never be mainstream. If Bitcoin were mainstream and every person on Earth used it, they'd get to perform two transactions in their entire lifetime before reaching the system's transaction capacity. Try doing some math instead of spouting nonsense.

Well you would had probably said same with internet, electricity, mobile phone and any new disruptive technology... Google Lighting network, and you will see that Bitcoin will scale to process all required transactions.

The very first web server in existence, which ran on a NeXT computer with a power consumption of 300 watts, could already process more requests per second than Bitcoin processes transactions per second today. The technologies we use today *scaled up*. Bitcoin does *not* scale.
