Crypto Sentiment Just Hit Extreme Greed for the First Time Since March 2024 — and ETF Investors Are Heading the Other Way

Bitcoin sentiment just hit its most euphoric reading in two and a half years — and one of the most closely watched analysts in crypto says that is exactly when investors should slow down and pay attention. A sentiment measure tracked by CryptoQuant analyst Darkfost briefly climbed above 89 out of 100 this week, a level he describes as “extreme greed,” marking the first time the gauge has reached that zone since March 2024.

The Hook: Extreme Greed Is Back

For regular Bitcoin holders, sentiment gauges are a bit like a market mood ring. They measure how greedy or fearful investors are at any given moment, based on price momentum, volatility, trading volume and social media chatter. When the needle swings hard in either direction, history suggests the market can be near a turning point — not because the gauge itself moves prices, but because crowded positioning leaves few buyers left when everyone is already optimistic.

According to Darkfost, whose measure incorporates Fear & Greed data alongside other inputs, the reading briefly pushed above 89 as Bitcoin rallied, before easing back from its peak even as the price attempts to hold current levels near 77,300 USD. His comparison point is March 2024, the last time bullish fervor reached comparable heights.

There is an important nuance here. The 89 reading is the high reached by the measure Darkfost follows — not the current value of every crypto sentiment index. Alternative.me’s separate Fear & Greed Index, for example, stood at 63, classified as “greed,” when checked for the report. That index showed 56 the previous day, 73 a week earlier, and just 29 a month earlier, according to its public page.

The Evidence: What the Data Actually Shows

• Sentiment peak above 89 — the CryptoQuant-linked measure briefly entered “extreme greed” territory, its highest since March 2024.
• Alternative.me at 63 — the widely quoted Fear & Greed Index reads “greed,” up sharply from 29 a month ago.
• Bitcoin near 77,300 USD — trading below the top of its 24-hour range, with a recent low near 76,393 USD and a high near 79,607 USD.
• ETF outflows of 462.7 million USD — U.S. spot Bitcoin ETFs bled money in all four sessions of the Sep. 8–11 trading week, per Farside data.

That last bullet matters most. While sentiment was racing toward extreme greed, institutional money was heading for the exits. Thursday alone saw a 282.7 million USD net withdrawal from U.S. spot Bitcoin ETFs — the largest single day of the week — before outflows eased to 13.2 million USD on Friday. ARK 21Shares’ ARKB fund posted the biggest weekly loss among individual products at 234.2 million USD, while BlackRock’s IBIT lost a net 52.5 million USD over the four sessions, according to the Farside figures reported Saturday.

The contrast is the story. Retail mood indicators were flashing euphoria even as the listed funds that supercharged the last bull run saw money leave every single session after the Labor Day holiday.

The Core Conflict: Greed Now, Caution Later?

Darkfost himself is careful about what his reading means. In his account, extreme readings become more useful to monitor when investor behavior changes alongside price. During a sustained bear market, negative sentiment can persist for long stretches without saying much. But when optimism spikes while a price rally stalls — which is roughly what has happened as Bitcoin struggles to hold its level below 80,000 USD — history says the combination deserves respect.

He is explicit that the observation identifies a risk to watch, not a forecast. Nothing in the data establishes that Bitcoin has begun a reversal, and sentiment gauges measure mood, not money. Neither the CryptoQuant-linked measure nor the Alternative.me index shows how much investors have actually bought or sold, and neither offers a price target.

There is also the macro backdrop. The Bureau of Labor Statistics reported this week that consumer prices rose 3.4 percent over the 12 months through August, matching July’s annual rate, while core prices rose 0.3 percent month over month. The Federal Reserve’s next policy meeting is confirmed for Sep. 15–16 — but what it decides, and how Bitcoin responds, remains unknown. Earlier this week, analysts told crypto.news that Bitcoin could remain stuck under 82,000 USD ahead of the Fed’s decision.

What This Means for Your Portfolio

If you own Bitcoin, the practical takeaway is not “sell everything” — it is “stop assuming the crowd is smarter than you.” Extreme greed readings historically cluster near local tops more often than near fresh breakouts. When everyone you know is already bullish, there are fewer new buyers left to push prices higher.

Three things are worth watching over the next week. First, whether the ETF outflow streak continues — four straight days of losses is a trend; one would be noise. Second, the Fed meeting: a hawkish surprise against an already-euphoric sentiment backdrop is the kind of combination that turns corrections into something worse. Third, whether Bitcoin can reclaim and hold the low 80,000s, a level analysts identified as the near-term ceiling.

The Verdict

Sentiment at a two-and-a-half-year high while institutional funds leak money is a classic mixed signal — the crowd is greedy, the smart money is cautious, and the Fed is about to speak. Darkfost’s warning is not a doom forecast. It is a reminder that the most dangerous moments in markets often feel the best. Treat this week’s euphoria as a reason to review your positions, not a reason to lever up.
