币界网报道：The Crypto Fear & Greed Index surged 8 points to reach 74 this week, signaling growing investor optimism in digital assets. This marks the highest level since Bitcoin's all-time high in November 2021, with the index now firmly in the "Greed" territory (scores above 55 indicate greed). The sharp increase comes amid Bitcoin's price rally above $52,000 and Ethereum surpassing $2,800, driven by strong inflows into spot Bitcoin ETFs and anticipation around the upcoming Bitcoin halving. Market analysts note the current sentiment reflects traders' confidence in continued institutional adoption, though some caution that extended periods of greed have historically preceded market corrections. The index, which analyzes volatility, market momentum, social media sentiment, and other factors, serves as a contrarian indicator - extreme greed often signals potential pullbacks while extreme fear may indicate buying opportunities.
