In my opinion, it is better to make your own research and trust your guts.

As you can see from the market, 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 one project 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 on Pre-ICO stage right now, you can check their website: https://ethermeta.com/
Or even better go through their Bitcointalk thread: https://bitcointalk.org/index.php?topic=2659058.0
