That is an unbelievable statement just on the face of it.
But if we say: "What is the energy use per transaction?" what then?
The inefficiency of crypto currency is legendary.
"likely"? What do you mean?
And that illustrates how incredibly inefficient crypto is
Gold mining and bitcoin are currently roughly on-par. But gold's energy usage isn't just mining. It's the entire supply chain from Cash 4 Gold stores, long term storage, smelting/recycling, etc. I don't have a good reference for the total cost of gold.
However, the point still stands. Datacenters in the US use total energy less than 2 bitcoins. How many of those datacenters are moving fiat around? Way less than half?
Things like brewing tea and heating houses take a ton of energy. Moving money around doesn't!
Crypto is a huge waste, and that site does not suggest otherwise.
Silicon and other electronic parts also get dumped into this market, when the capacity used to build those devices could be used for other things.
