how long does it take to receive a payout for the masternode on this?>
I'm running one but haven't received it yet..
The wait for 1st reward is around 38 hours. The amount of nodes on the network determines this, the more nodes the longer the wait.
If your cold wallet indicates that your MN is enabled and the API tells you that everything is OK than everything is running fine and it is a waiting game.
