The Crypto Fear & Greed Index has increased by six points to reach 19, yet it remains in the 'extreme fear' category. This index, which gauges investor sentiment on a scale from 0 to 100, incorporates data from market volatility, trading volume, and social media activity. A score of 19 indicates significant investor caution, a sentiment often observed during market downturns or corrections. Historically, such low levels have occasionally been seen as potential buying opportunities for long-term investors.
