Privacy coins could facing law problem in the future, and if its happen i think it could impact bad on the price. Also, afaik many exchanges prefer not to list privacy type of coin.
You didn't even need to think so hardly about this project. Ghost almost dead and this token fully with gimmick by the developers. So many people have been loosing a lot of money by putting their money into this garbage coin dude. The privacy coin could being the exchange site a problem with regulators.
that's why it lacks of demand right now due to the regulation.
