It is said that Proof of Stake will be the mainstream consensus mechanism in the long run. Regarding the nature perspective I totally agree. But it has been rumoured that Proof of stake is more democratic way of having consensus since at proof of work mechanism; people who has more money can invest more to hardware so they have the competitive advantage. Again correct but if we think the other way around if you have more money and buy more Ether tokens you are again have the competitive advantage at the Proof of Stake consensus mechanism. OR am I missing something?
