In my opinion, it is better to make your own research and trust your guts.
The most of the privacy coins are undervalued right now.
The best opportunity is to find a
privacy-related project with a low total supply
(less than 100M), that way the price will be increasing much faster.
I recently found
a hidden GEM called
Ethereum Meta, it is related to anonymity and untraceable transaction. They have a very interesting project to build the Anonymous E-Market Place.
They are already trading on some exchanges, you can check their website:
https://ethermeta.com/Or even better go through their Bitcointalk thread:
