Couple of things.  First, I have two masternodes that I just got set up yesterday.  The first has generated three 2-coin transactions, and the second hasn't generated anything.

To check the status of your masternode, be sure to look at debug.log:

cat ~/.chaincoin/debug.log

or "follow" the log with this:

tail -F ~/.chaincoin/debug.log

You can see messages about whether your masternode is valid.  In my log, when my masternode made the transition from invalid to valid by getting 15 confirmations, the system logged this message:

2017-07-10 08:04:21 CActiveMasternode::ManageStatus() - Is capable master node!

Check to see if you can find this message in the log:

cat ~/.chaincoin/debug.log | grep "capable"

Also try this:

chaincoind masternode list | grep ""

Where is your masternode IP address.  You should see your node in the list with the word ENABLED after it.

BTW take this all with a grain of salt, I'm completely green.
