How to read the Global Crypto Index Explorer
What 24H vs 30D means, when a print is official, and when you are looking at a market-cap proxy.
The explorer lists public crypto indices. Some rows are licensed prints (CoinDesk 20 via Yahoo, Bitwise 10 via BITW). Others are transparent proxies built from CoinGecko market caps because Nasdaq NCI, CF Broad Cap, SoSoValue DEFI.ssi and SIX CMI 10 do not publish a free feed.
24H / 30D are percent changes on that series. They are not implied vol and not a forecast.
Use Analysis for a directional summary (bias, confidence, range). It is descriptive, not a trade plan.
