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: https://bitcointalk.org/index.php?topic=2659058.0
