Using a data set on social sentiment by crawling Twitter and trading information on an exchange in Korea. We empirically study the linkage between social sentiment and asymmetric information in two cryptocurrency trading settings. Our results highlight the differentiated impact of positive and negative sentiment variance on information asymmetry according to 1) the spillover effects and 2) the leverage effect of social news characterizing social sentiment.
