Dash (https://www.dash.org/ https://www.dash.org/). Currently return is just over 10% ROI per Master Node (just a full node Bitcoin client running on a server for a few $$ a year). Aside from the 100%+ increase in the currency since I bought it, running five Master Nodes nets about $10,000 a year of passive income.
