index = Crypto Fear & Greed reading (0–100), last observation of each UTC day
The Crypto Fear & Greed Index blends volatility, momentum, volume, social activity and Bitcoin dominance into a single 0–100 sentiment score. Coinfuty polls it hourly and keeps one reading per day permanently, so the chart builds a history against price that the source itself only shows for a limited window.
Extreme greed (above 75, and especially the 90 level used here) has coincided with local and cycle tops; extreme fear below 25 has marked capitulation lows. The index is a contrarian tool: it is most useful at extremes and says little in the 40–60 band.
78 (Greed) as of Sep 4, 2026.
Sentiment is euphoric — volatility, momentum, volume and social chatter are all stretched. Readings above 90 have coincided with local and cycle tops; the index is a contrarian gauge that is most useful at its extremes.
It is a composite of volatility, market momentum and volume, social-media activity and Bitcoin dominance, scaled 0–100. Coinfuty records the last reading of each UTC day and keeps the history permanently.
That is when Coinfuty began storing daily readings; earlier values are not backfilled, so the chart lengthens by one point per day.
Coinfuty computes every series on this page from daily BTC close prices and public constants — the Bitcoin halving schedule, block subsidy and published regression coefficients. Values refresh nightly (00:20 UTC) and the current day is patched hourly. These are historical, backward-looking indicators; nothing here is investment advice.
