Another one that has staking is DeepOnion. It's a Pos/PoW hybrid one, you can mine it (or buy it) and also stake the ones you have. Staking is as easy as letting your wallet running on your PC, or you can even use a Raspberry PI for it! Until june the staking gives a 10% return of your owned $ONIONS, and from that moment a 5% return, which isn't bad either.
