Would be more useful if you can tell how much NIX you earn daily with one GhostNode. According to other users posting in this thread, right now ROI is under 40%, which with current price should be around $6000 yearly, $500 monthly and ~$17 daily. Should be gradually going down too, since we there will be more & more masternodes running. Of course this should change when fees from DEXes will start flowing into the system.
