Cronos masternode's ROI looks good, but the issue for now is low volume of Cronos on Crex24 exchange.
Profits will become real ones if Masternode investors can sell their coins at expected price, and volume is one of most important things to help them taking profits well.
This exactly. Crex is an excellent exchange, however, it just doesn't have the fairly massive liquidity something like this requires. I have bought in @ less than full node and hosted on CHT. An additional exchange would be nice as it'd provide the security of liquidity to kick it up a notch or two.
