The significant fluctuations in public opinion on social media regarding cryptocurrencies can be quantified through sentiment analysis tools. By analyzing the number of positive, negative, and neutral posts, comments, and mentions, a sentiment index can be created. This index can then be correlated with price trends. For instance, a sudden surge in positive sentiment may precede a price increase, while a rapid rise in negative sentiment often coincides with price drops. However, the relationship is not always straightforward, as other factors also influence cryptocurrency prices.
