Maybe you misunderstood me. Maybe I misunderstood you.
In the article on this link there is nothing new for me. Nominally, many coins fit the definition: "Only controled supply or supply by calculable criteria allows that every published unit of one currency have the same value". But we can have different cost of electricity and consumed energy of video cards, which we extract, which allows for example you to extract for the same production capacity the different numbers of coins. Correspondingly for you the cost of the extracted coin will be less than for me.
