There's been more and more talk pretty recently, mostly over the past week or so. They are trying to get a budget for their marketing team so in the meantime it's pretty much been word of mouth and community members working together on twitter campaigns and articles. Word on the street is that Poloniex will be adding it here soon and then it should really be taking off once that's confirmed. I'm sure the recent pump in all of the coins has helped quite a bit but this coin was very undervalued before that took place. A lot of these coins will eventually correct and I think that's where PIVX is going to push ahead.

https://pivx.org/pivx-team/ That is the official team, some of them are aliases since it is a privacy centered coin. The hype is mostly because nobody knows about it, it's only trading on Bittrex at the moment and there is a huge potential for what it can do. Privacy is the biggest feature with this coin, and when you have coins like Bitcoin where you can track transactions back through the blockchain or Dash where they've teamed up with a company to mark coins as "dirty" so they can't be spent and you might get stuck without even knowing it, this is a coin that's doing something about it. Arguably you could say any coin has potential but if you see the community you'll understand how this one is different. Just taking part in the slack channel you can tell this isn't going to be another pump and dump scheme because everyone wants to make the next best coin, something that will be useful.
