I remember when Dash launched it had to stop and relaunch a few days later due to problems. Now it is one of the most successful coins ever and people that held made a killing. So I would not read to much into this price correction PIVX has at the moment.  

I am buying more while the price is so low.  As a practical matter, PIVX is the 1st mover with POS/zero knowledge proof protocol plus with its self funding mechanism in my opinion makes it one of the most viable competitors for the long run.
