Your node40.com account monitor page is a great resource.
- The most accurate status of your masternode is available from the Monitor page. We get the status message directly from the network. We have found the monitor status of the Dash Core Wallet tends to be buggy and should not be relied upon as an indicator of your masternode's health. Note this is not a Node40 issue, but rather an issue with the wallet itself. If your masternode ever requires a remote-start we will reach out via email with instructions and an explanation of why the start is required.
- A dark green highlight represents a reward payment within the last 24 hours, and then it will switch to light green for the next 25-48 hours.
Where are my rewards?
The network pays out rewards to your masternode public key. That means the rewards are in the wallet associated with your masternode.
If you move rewards, they are technically no longer rewards but rather inputs to a new transaction. If the Node40 monitor page shows that you have 10 Dash in rewards, but you then sent those 10 Dash away from it's public key, the monitor page will update to show 0 Dash in rewards.
