PIVX is one of the coins I recommend to invest in. PIVX is basically a fork of Dash but the PIVX community will introduce some improvements to it that they think are going to make it more valuable than Dash. Yesterday they finished the planned implementation of the zerocoin protocol which makes the coin truely anonymous. The zerocoin protocol is a state-of-the-art anonymous protocol that makes PIVX more anonymous than Dash. No wonder its price exploded yesterday. I still think the coin has a lot of upwards potential as the team is really progressing fast and agressively. The coin is also only listed on Bittrex. If it gets listed on other exchanges like Poloniex, something that I see happening, the price will go bananas.
