Many asked if you can stake and be a masternode at the same time, and no the masternode wallet can't stake, or we can't have it to stake, as you need 13342 CBIT as collateral or we can call it Proof of Service.
And I would advice not to have any left over coins there in the wallet you run as masternode, as you need to send exactly 13342 CBIT to the collateral address. It would be better to start up a second wallet and transfer the remaining coins to it.
