I'm not defending POS, I just find it curious that this website you quoted represents it like that.
As a matter of fact this is something I've brought up a lot of times about a project like Cardano which, reading through their stuff and listening to them, sounds like they say they've produced a secure POS system, but I never get a clear and convincing explanation. So I remain firmly in the BTC POW camp.
openAI chapt also will say POS is better
Q u need ask - 99% coin reward is mined - fight for reward makes no sense even if price is big
what n why motivation of hashing in BTC chain and not in other chains from fiat profit motive?
becos industrical miners DONOT CARE about bitcoin - they wanna covert wasted ENERGY BP ARAMCO TOTAL -> tangible FIAT PROFIT
HASH CAN REDUCE but should NEVER FALL to make it easy of other large miners to 51% attack - provided people are still 905 coin ONCHAIN and not converted to ETF
