The article is not wrong, but it's about a coin that was originally POW and decided to become POS. Apples and oranges. Paycoin was already cloned from a POW/POS coin and hardforks were entirely their own doing. Many altcoins are POW/POS, certainly not a new concept.
Why are you trying so hard to find a way to justify obvious lies? Better focus on actual fact checking. It's really easy to look up Peercoin and find that it was introduced in 2012.
I don't understand each of the different reward structures so well, and when I tried to research, that article came up. Could you try assuming good faith for a while? How come you're calling me out for asking a question but not anyone who keeps on saying that the paybase reviews were false after they've been shown to be false? It seems that you only say something when you don't like something I say. Is that impression wrong?
