According to the ROI spreadsheet:
https://docs.google.com/spreadsheets/d/1Y8uRsftL_uUcDPPiRvDDxJwI2ftLZq1iPavKaGfrF_c/edit#gid=0 it seems the network is currently oversaturated with service nodes, being only 79% profitable (!) compared to just staking 5000 coins. Theoretically, market efficiency means that people will start staking more instead of setting up new nodes and/or switchover nodes to staking, so that nodes become as or more profitable as staking. But I guess it takes some time to happen.
Is there a plan for implementing some automatic mechanism to help rebalance this or guarantee nodes to get a higher profitability than normal staking?
