proof of stake is not safe. Poof of work is power hungry. Choose one.
seeing from which side?
whether from the type/ series GPUs?
if see from there, of course, have a different such as if see from the power consumption between NVIDIA and AMD cards. of course, NVIDIA doesn't have hungry power consumption but if see AMD such as R9 I agree has hungry power consumption.
I was talking about overall though. Say bitcoin uses as much electricity as a country. If someone did study on the whole crypto market, it could be so much more. PoS has little power consumption compared to pow.
