PIVX is a relatively young fork of DASH, but pretty much exclusively proof-of-stake, I believe. I think this has something with to do how closely they seem to move together as you can see in the comparison overlays. It's for this reason I see DASH doing the same moves, and going down one more time.
Although I dislike proof-of-stake coins from a conceptual point of view, there is no getting around the fact they tend to have MASSIVE highs & lows compared to traditional proof-of-work coins. (XEM is a good example).
So as a crpto-trader, I'm loving them.
If you did want to do some investing, getting a good chunk of PIVX at the floor and keeping it your own wallet as a "mining" node would be a pretty good bet I would say. The floor could be very far down. I'm long already but I've got more buys lined up all the way down to 0.00008 BTC
On a side note, DASH is both proof-of-work and proof-of-stake. Even though it's a veteran coin, DASH still has plenty to mine, but the entry requirements are pretty daunting if you wanted to join in.. 10,000 DASH in your wallet! To be fair, I don't think they would have seen the explosion coming when the white paper (or whatever) was made.
Seems a steady slow mine and great technical foundation is a winner in general in the crypto world.
