One important vector in passive income investing with masternodes is when to invest. Buying a masternode for $1,000 which yields 10% will give an ROI of $100 but if that masternode goes 5x (i.e $5000) and still gives an ROI of 10% that would be $500. Investing in the established ones is safe, but a share of your portfolio can also be focused on low cap http://nodesofvalue.com/low-cap-masternodes-with-potential/ and upcoming masternodes http://nodesofvalue.com/upcoming-masternodes/. The market might not have priced these in to their full potential. Do you own research! #DYOR
