Privacy like security only becomes and issue when it stops working.
I would expect to see some major incidents in the next few years that will help boost the price but expect some long slumps in between!
Personally I think crypto and the privacy coins especially are too technical for most users to use correctly and really benefit from the privacy features.
Monero is probably the best but I have to use the CLI for the moment as I got hit with the badcast issue.
These type of issues cause be a bit of pain and a few hours if not days of research not sure how a non technical person would cope.
