So why didn't it grow in 2015, 2016? Why now? PIVX was @2.90$, is now at 1.50$. How long will it take for a person to have invested at 2.90$ if the price stays at that level or plummets to 0.25$. Masternodes just inflate a coin, doesn't earn any income if the price can't keep its level.

This coin does not solve any problems. As soon as anyone starts to seriously sell their stack the price will drop like crazy. Your shitcoin already dropped by 50% today...
