We have a lot of thoughts on Pivx at Crypto Briefing. I've reviewed several of the ZeroCoin and other privacy coin protocols. Our team looked into Grin pretty recently too. I like Pivx as a currency, but it's certainly not a get-rich investment that'll skyrocket, as you said. Of course, every crypto will skyrocket if someone manipulates the market the way Tether did with BTC to pull everything up. It's only a matter of time before mining companies, exchanges, or random Madoff schemes figure out a way to manipulate the crypto market. Those small handful of the 2000+ crypto projects are the ones that'll get media attention over the next few years, while projects like Pivx continue innovating what it is many of us wanted from crypto in the first place... https://cryptobriefing.com/what-is-pivx-introduction-to-piv-and-zpiv-tokens/
