CoinMarketCap’s Crypto Fear and Greed Index slipped two points from yesterday to 37, leaving the market in the fear zone. The gauge is designed to show deeper fear as it moves closer to zero and stronger optimism as it approaches 100. CoinMarketCap says the index is calculated using price movements among the top 10 cryptocurrencies by market capitalization, market volatility, derivatives-market indicators such as the put/call ratio (options bets on declines versus gains), the stablecoin supply ratio (measure of stablecoin liquidity) and the company’s own search data.
