Does PayCoin adds something new and useful?

Does PayCoin adds something new and useful or is it just yet another clone (of Peercoin, it seems)?. Its paper describes the features of Paycoin listing those of any cryptocurrency, but as if it was something new, which it is not.

Why is the value of its supply (the so called “market capitalization”) so high?. It varies between just above and just below that of Peercoin.

Is PayCoin being used for anything else than speculation?.

It seems a lot like a “pump and dump” scheme.

Thanks.
