"The average energy consumption for one single Bitcoin transaction in 2020 was 741 kilowatt-hours."
Bitcoin has achieved almost none of it's goals, becoming digital gold instead of digital cash. It's slow, expensive to use, it's privacy measures are ineffective, and the value is too variable.
What is has achieved is breaking the ground and that such a system is useful. I think there's a place for cryptocurrency, but none of the current implementations are going to be THE cryptocurrency.
