Crypto traders have swung from fear to greed in less than a fortnight.
The widely watched Crypto Fear & Greed Index reached 74 on Tuesday, up from 27 on Aug. 12, before easing to 65 on Wednesday. It spent every day from late July through Aug. 19 in fear territory, dipping to 25 on Aug. 6, which the index classifies as “extreme fear.”
The gauge scores market mood from zero to 100 by blending bitcoin's volatility and trading momentum — which carry most of the weight — with social media activity, bitcoin's share of total crypto value and Google search interest. Anything above 50 counts as greed.
As such, it measures what traders are doing now rather than forecasting what happens next.
Data shows the index last sat this high on Oct. 5, 2025, five days before the crash that forced roughly $19 billion of leveraged positions to close in a single session, still the largest such event on record.
The shift in sentiment has come with gains across the market. Bitcoin climbed from below $68,000 last week to nearly $80,000, while some major tokens added as much as 70% as traders turned back toward the so-called debasement trade after months in which speculative attention had been dominated by AI, memory chips and semiconductor stocks.
Further down the market the moves are larger still. Dogecoin has gained about 24% over the past week. Smaller memecoins have run far harder, with Thinking Cat up 131% over seven days, Cash Cat 113% and Dog (Bitcoin) close to doubling.
Money moving into thinly traded tokens like these is a strong indication of risk appetite returning, and such high readings can indicate investors are getting carried away and that the market may be due a correction.
The next test comes Friday, when Federal Reserve Chair Kevin Warsh delivers his first Jackson Hole keynote as chair. Markets are looking for clues on rates and inflation after weeks of volatility in long-term Treasury yields, whose recent retreat helped kick off bitcoin’s run from below $68,000.
