I definitely vote for DeepOnion as the best privacy coin. I have thoroughly enjoyed my time investing in this anonymous coin that uses the Tor network. I know I know, everyone says that about their favorite coin. Well here are the reasons why I like this coin and have invested heavily into it:

-Free Airdrop (I could stop here, but won't)
-Integrated with Obfs4
-Secure Wallets for Windows, Linux, and Mac (Mobile Wallet almost out)
-Amazing community (They hold contest, bounties, giveaways, and other ways to earn more onions).
-Active and Deeply committed Dev team.

The list goes on. Check out the white paper here: https://deeponion.org/White-Paper.pdf
