Has anyone here ever mined coins that offer master nodes?

 Have only just started looking at masternodes, looks like money just gets locked away and this helps to pump the price over time correct?

Some of these could be quite profitable for mining and then dumping into a preferred coin?

My thoughts anyway as they seem to offer almost double the return of main coins like eth, zcash, or currently btcz

cheers for any responses/suggestions
