Prior to being able to stake or transfer Gridcoin to/from the Gridcoin client you need to fully sync the gridcoin client to the latest block on the blockchain (green tick under connections indicates a fully synced wallet)
You can download a snapshot of the blockchain from within the client by clicking 'Rebuild block chain | Download Blocks'.
Note: The 'Download Blocks' feature require the gridcoin client to be running as administrator in windows; without admin permissions these features will throw an error.
If you're having issues with 'Download Blocks', you can manually download the latest snapshot here.
Note: The snapshot will not fully sync your client, but will rather bring you up to 80-90% sync. Allow your client to manually sync after the snapshot has been implemented.
If you are unable to acquire connections to the Gridcoin network, attempt the following:
Verify that your computer time is synced to your configured time server.
Investigate whether or not your ISP is blocking the P2P traffic.
Regularly verify you're running the latest version of the gridcoin client, as there are frequent updates. Notices of updates are posted regularly on Reddit/Twitter/IRC.
Both the 'Download Blocks' and 'Upgrade Client' features require the gridcoin client to be running as administrator in windows; without admin permissions these features will throw an error.
Acquire a positive balance of Gridcoin prior to proceeding to step 4

In order to mint yearly compound interest, a positive balance of GRC is required (This is the case for all POS cryptocurrencies).
There are 960 blocks per day that you can attempt to stake. If you've got 1% of the total Gridcoin supply, you'll approximately stake 9.6 blocks per day.
The formula required to work out the quantity of coins to stake in a period of time is:
