How we arrive at these numbers
Here is the provenance of every number on this site, and the age we allow it to reach. Figures are fetched when the site is built and written straight into the page, so a crawler and a reader see identical text — the cost is that each page has an age, which we print instead of hiding.
Sources
| What | Source | Considered current for |
|---|---|---|
| Prices, 24-hour change and market capitalisation | public market-data sources | 30 minutes |
| Fear and greed index | a third-party market-sentiment index | 12 hours |
| Open prediction markets and implied odds | public prediction-market data | 60 minutes |

The path the data takes
Sources are read on a schedule, and the pages are rebuilt from what came back. We do not fetch from the browser: a page that populates after load reads as empty to a crawler, and one public call per visitor runs into rate limits almost immediately. That makes a page exactly as fresh as its last build, and so each block states the moment it was collected.
Why blocks get marked out of date
Past the window in the table, a snapshot is labelled stale rather than passed off as current. A crypto price three hours old has stopped being a price and become a historical figure — showing it undated would make this page look steadier than it is.
Things we leave alone
No smoothing, no rounding up, no re-ordering to make a number read better. The percentage moves are the source's own 24-hour figures. The prediction-market odds are what the market implies, not our view, and 60% on a leading outcome is precisely as uncertain as it sounds. The sentiment index is a third party's read on the whole market, not on any single token.
Commission
Links on this site pay us a commission on sign-ups. It buys nothing above: sources are public, figures are reproduced as fetched, and the platform we point to has no say in the tables.
