#市场情绪观察 Market sentiment monitoring is the process of analyzing investors' overall attitudes and expectations towards the cryptocurrency market. This sentiment is usually driven by emotions such as greed, fear, optimism or pessimism, and can be perceived through channels such as social media, news reports, market comments and trading behavior. For example, when the market is generally greedy, overbuying may occur, leading to price bubbles; while when fear dominates, panic selling may occur, causing price crashes. Market sentiment indicators, such as the Crypto Fear and Greed Index, provide investors with a way to quantify market sentiment. Understanding and observing market sentiment is essential for developing trading strategies and risk management, as it often indicates short-term market movements.
