Causality between Sentiment and Cryptocurrency Prices
This work applies Narrative Economics to cryptocurrency, offering insights for investors and researchers, but it is incremental as it adapts existing methods to a new domain.
The study investigated the relationship between Twitter narratives and cryptocurrency prices by combining topic modeling and sentiment analysis, revealing 4-5 key narratives and observing a strong link to price movements in some cases.
This study investigates the relationship between narratives conveyed through microblogging platforms, namely Twitter, and the value of crypto assets. Our study provides a unique technique to build narratives about cryptocurrency by combining topic modelling of short texts with sentiment analysis. First, we used an unsupervised machine learning algorithm to discover the latent topics within the massive and noisy textual data from Twitter, and then we revealed 4-5 cryptocurrency-related narratives, including financial investment, technological advancement related to crypto, financial and political regulations, crypto assets, and media coverage. In a number of situations, we noticed a strong link between our narratives and crypto prices. Our work connects the most recent innovation in economics, Narrative Economics, to a new area of study that combines topic modelling and sentiment analysis to relate consumer behaviour to narratives.
