https://www.cnbc.com/2021/02/22/yellen-sounds-warning-about-extremely-inefficient-bitcoin.htmlWhy thank you Joe Biden for your nomination. Bitcoin is tumbling for multiple reasons today but I don't find her comments particularly true or useful. And besides, if we're talking about energy usage, does it not take a metric ton of energy to continually print USD? Pretty sure there was more printing within the last two years than ever before in US history. Those energy bills stack up, ya know.
Lets Stop the energies nonsense. How many banks are in the world, all need heating/aircon, lights, computers, automatic doors.... on top is all the ATMs.
Then there is WesternUnion, Moneygrams...
Next Bitcoin mining rewards halves about every 4 years and a lot of old inefficient miners have to close, shut down for good.
