I think DeepOnion is an excellent project with a huge potential for 2018, it's a privacy coin with a PoW/PoS combination for mining, Anonymity is guaranteed through the TorNetwork and DevTeam is working to introduce DeepSend which will introduce a further level of anonymity. Furthermore it has some unique features such as DeepVault, which gives the opportunity to secure files through the registration of a linked hash on the blockchain. Last but not least DeepOnion has a great community behind it and a Dev Team is really, it continuosly updates the wallet and has promised many innovations during 2018 (Android Wallet, DeepSend, VoteCentral, etc.). It's definitely one altcoin to follow really close.
