PIVX is probably good. I gained a fair bit while staking 1776 Token, which is functionally similar to PIVX, but when I got my masternodes setup the rate of masternode rewards was hugely greater than the staking had been. However, while staking with a tenth of my previous balance, the staking successes have been maybe 99% less! ... With time the masternodes also should reduce, as other people set them up too. You can checkout 1776 Token at the following address. We should be listing on exchanges a few days into April, I think. https://www.freedom.social/p-1776principles
