My biggest issue with it is that trading is very centralized (~97% on Bittrex) as of now. Hopefully Poloniex will eventually add it.
Vehemently agree with every word. I have a crypto analysis youtube channel (address in sig) where I talk about all things crypto (Everything from BTC updates to ByteBall news, interesting ICOs, wallet staking, etc.) Out of all of them, PIVX is my favorite project for the reasons you stated above and the underlying community itself (best/most supportive in the crypto space, imo)
Also, in my last episode, I ran some compound interest calculations and PIVX staking is a goldmine right now. I projected 31.1% (albeit that doesn't take into account the diminishing block rewards taking place over the next couple months)
