Bitcoin is the king of cryptocurrency and in a kingdom we have only one king, which means no one can be like or act like the king. This is how bitcoin is to these altcoins, since they are duplicate of bitcoin and bitcoin is decentralized while most of the altcoins are centralized making it impossible for a PoS coin to be like Pow because the two are different.

It is impossible for you to see such altcoins, so just forget about it.
