PTS is totally different from other cryptocurrency, its not suprising to me to see it running away. Bitcoin is really "expensive" by the estimation of most observers, so these other "cryptos" are just as good since they're so undervalued compared to Bitcoin. Litecoin has long been called the silver to Bitcoins gold so the analogy makes sense and the upward price pushes them all up as a rising tide lifts all boats.
The market is as frothy as i've ever seen it, this is money spilling from bitcoin into everything around it. PTS is not around Bitcoin, PTS is new and unique and frankly hasn't had the best public entrance so it doesnt have good hype surrounding it except to the core believers. Once Invictus delivers something expect a whole new ballgame, until then it's just another altcoin nobody owns.
