Your unsettled earnings will be automatically settled once you reach 5 MYST.
However, If you wish, you can manually settle your Balance from Node's internal NodeUI to your external wallet address at any time. To do so, simply visit http://[ip-of-your-node]:4449/#/earnings and click the "Settle now" button to manually settle your Unsettled earnings.
If you have any questions about manually settling your earnings from Node, please reach out to our support team. We're always happy to assist!
