BUYER BEWARE
This is a classic ponzi scheme. There is no real use for this coin so the only buyers are people who are wanting to run a master node. When there are too many master nodes and ROI goes down to nothing there will be no more buyers left for this coin and everybody will be stuck and unable to sell. The only people who are making anything are the ones that got in early and are selling into the people buying master nodes. You have been warned. caveat emptor
This can be true, however, there's already over 80% of coins staked to run masternodes, so there just is not enough coins in circulation to pull off a scheme like you are describing. Maybe if there were 20% of coins staked, then yes. The way it is right now, you are safe in running masternode(s) and keep mining the coins, it will take a while before there's any real danger of this coin tanking.
One way it can tank that's highly unlikely (since 80% of coins are staked...), is if the majority of people with masternodes (those making up the aforementioned 80%), sell off their coins.
Also keep in mind, this coin is only over a month old.
