Just a quick update for those interested. MasterCoin Masternode gave so far 1 reward in 60+ hours, 2-1/2 days !!!.
You might as well not setup your MN and leave it staking, you might get slightly more. Nice joke MC developers !!!
Maybe you're doing something wrong or you are just unlucky...
I have 3 MNs and have 5+ rewards per day from each MN.
I have MNs right from the start of POS and never had issues with them.
