# Estimated APY vs Time
-The plot below shows estimated APY over time. It brings together data from the [OCEAN reward schedule](reward-schedule) and estimates of **amount staked (yellow line** in plot).
+The plot below shows estimated APY over time. It brings together data from the [OCEAN reward schedule](reward-schedule.md) and estimates of **amount staked (yellow line** in plot).
**Green is total APY** from passive and active rewards. **Passive rewards (black)** provides a great baseline with upside in **active rewards (green)**. For example, in DF29 wash consume became unprofitable and led to a drop in DCV and therefore active rewards.

-Is there a way to check the duration and amounts of OCEAN locked on-chain for all wallets?
-
-Yes, this information is available. Indeed, there is a technical aspect involved. You'll need to have some technical knowledge because you'll be required to query the subgraph. You can find a working example of how to get the list of holders [in the subgraph documentation](../developers/subgraph/get-veocean-stats#get-the-veocean-holders-list). Feel free to run the script by clicking on the "run" button.

**Predictoor DF makes Volume DF more attractive than status quo**, because the volume-based bounds on weekly rewards trends tend to be markedly higher for prediction feeds. (The Appendix has details.)
