- Linus Torvalds, creator of Linux, does not believe in cryptocurrencies, calling them a vehicle for scams and a Ponzi scheme.
- Torvalds was once rumored to be Bitcoin creator Satoshi Nakamoto, but he clarified it was a joke and denied owning a Bitcoin fortune.
- Torvalds also dismissed the idea of technological singularity as a bedtime story for children, saying continuous exponential growth does not make sense.
From what I found, and varies due to values/date, looks like a PoW transaction is about 2+ million times more energy than traditional banking. PoS is over 1000 times less than PoW, so about 2+ thousands times traditional banking. But transitional banking has other problems. For one, the market of payment is stitched up. Not like openness of a crypto currency.
