Woofun AI reports that market sentiment has rapidly shifted toward greed, with the Crypto Fear & Greed Index reaching 74, its highest level since the period immediately preceding the October crash. This surge in risk appetite coincides with Bitcoin's rally and sets the stage for Federal Reserve Chair Kevin Warsh's upcoming keynote at Jackson Hole.

Structurally, the index measures market mood on a scale from zero to 100, blending bitcoin's volatility and trading momentum—which carry the most weight—with social media activity, bitcoin's share of total crypto value, and Google search interest. Readings above 50 indicate greed, while the gauge recently dipped to 25 on Aug. 6, classified as "extreme fear," after spending every day from late July through Aug. 19 in fear territory. The current reading of 74 on Tuesday, down from a low of 27 on Aug. 12 and easing to 65 on Wednesday, mirrors the level seen on Oct. 5, 2025. That date was five days before the crash that forced roughly $19 billion of leveraged positions to close in a single session, remaining the largest such event on record.

Woofun AI data shows Bitcoin climbed from below $68,000 last week to nearly $80,000, while some major tokens added as much as 70% as traders returned to the debasement trade after months dominated by AI, memory chips, and semiconductor stocks. Further down the market, Dogecoin gained about 24% over the past week, while smaller memecoins surged more sharply: Thinking Cat rose 131% over seven days, Cash Cat jumped 113%, and Dog (Bitcoin) nearly doubled. This capital flow into thinly traded tokens signals a strong return of risk appetite, suggesting investors may be getting carried away.

Such high readings often indicate that the market may be due for a correction, especially as traders look for clues on rates and inflation. The next critical test arrives Friday, when Federal Reserve Chair Kevin Warsh delivers his first Jackson Hole keynote as chair. Markets are closely watching for policy signals after weeks of volatility in long-term Treasury yields, whose recent retreat helped kick off bitcoin's run from below $68,000.
