Decred (DCR). Current profit around 1.8% per month and each PoS gives you a vote power in the coin's future (check out more infos in Decred topic).
It is also flying "below radar" - it will annunce lightning nextwork next days and several other features defined in the roadmap. The dev team is delivering in time.
DCR, I'm on it, too. These devs are slightly off the common rails this golang based software causing me issues to maintain, but the project looks promising. And I can delegate the staking.
Another one would be LSK Lisk who will enter the buy zone early next year 2018 since the last big event about releasing a developer API ... has been a mess. Postphoned for monthes now. But the team (as can be seen on their video footage) looks promising, the archetypical young geeks.
