In 2018 we will see x10 for Pivx. One of best projects.
I think you will see close to $10 before 2018. Once the zerocoin implementation is release, the price will go up.
Then a masternode would be worth 100.000 $ ... guess some will then sell off and the masternode count will decrease .... not many will pay 100.000$ to install a new masternode ....
It did take a bit of time to let it sink in: when there are less masternodes, the seesaw mechanism will increase the rewards for masternodes, as an incentive to... keep it running.
