- 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.
Plus the hardware needed for each person atop the extra power useage.
Not worth it when May already feels like Aug
Everyone has hardware enough already. Your phone is perfectly good enough. For tills it will be easier to implement. No nonsense with a card machine and things like WorldPay and whole locked down PC. The hardware and platform wouldn’t matter.
