Crypto market hits extreme greed as Bitcoin rallies 24% in a week

CoinMarketCap’s Fear & Greed Index rose from 41 to 81 in a single week, placing the cryptocurrency market in the “extreme greed” zone for the first time since late 2024. The surge follows a 24% weekly gain in Bitcoin, which briefly topped $80,000.

Sentiment shift

The index, which aggregates price momentum, volatility, derivatives activity, market composition and social engagement, climbed 45 points over the past month (from 36 to 81). Extreme greed signals strong buying interest but also warns of potential overheating.

Bitcoin’s price rally

Bitcoin broke out of a $62,000‑$65,000 range on Aug. 19, surged past $70,000 and peaked near $81,255 before settling around $79,000 on Aug. 25. The advance was amplified by short‑position liquidations estimated at $2.7 billion in a 24‑hour window, with over $1 billion of Bitcoin shorts closed in about an hour.

Market‑wide impact

• Total crypto market cap reached roughly $2.67 trillion, up 23.8% in seven days.
• Bitcoin retained about 60% of total market value, with dominance near 59.7%.
• Other large assets also rose, though Bitcoin drove most of the sentiment jump.

Drivers behind the rally

Two key factors coincided with the price move:

1. U.S. spot Bitcoin ETFs: Net inflows of $517 million on Aug. 19 and $606 million on Aug. 20 added more than $1.1 billion in two days, with $1.9 billion entering the funds over five days.
2. Macro backdrop: The U.S. Treasury announced a planned increase in liquidity‑support buybacks for long‑dated bonds, prompting a drop in Treasury yields and a weaker dollar, which many traders linked to a more favorable risk‑asset environment.

Alternative sentiment gauge

Alternative.me’s index, which focuses mainly on Bitcoin, remained in the “greed” zone (six points below its extreme threshold), reflecting methodological differences such as heavier weighting on Bitcoin‑specific data.

Outlook

Analysts note that continued spot ETF inflows and sustained macro support will be needed for Bitcoin to stay above $80,000 after the short‑covering squeeze fades.
