Ethereum is not a coin, it is "Next-Generation Smart Contract and Decentralized Application Platform"

Protoshares "main goal is to provide coin holders with shares in new coins and by that give them a financial profit if these coins become successful and have a high value."

Also I dont think Doge and Quark are really long term coins. Doge is determined to fall now and Quark had a rush already? I think QRk will stay where it is

Anyway it would be interesting to know more about why Peercoin is so undervalued:)
