I don't know if it's the future of mining... I invested in few PoS masternodes and they're pretty new projects.
I think PoS masternode bubble ended few months ago. I saw coin developers selling first masternodes in auction (5 BTC) and now coin is abandoned. Masternode price now is 15$.
There have lot projects like your. They can't control their coins price and they sell out their coins and dump the price.
