Yeh...Peercoin has a pretty strong place in my heart but note I'm biased. The creator Sunny King and another guy who is a really good friend of mine come from that community and I believe beyond bitcoin is the only place in crypto media where they did pop up :D

But Yes....In short, without Proof of Stake, there wouldnt be Delegated Proof of Stake or any of the number of iterations that exist today. So right on bro ;)

P.S. I do hold peercoin. lol...
