【Abstract】Using topic modeling analysis, we identify six bitcoin-related topics - Investing, Bitcoin Market, Regulation, Private Equity, Cybersecurity, and Macroeconomy - discussed in the Wall Street Journal and document differences in their sentiment (polarity) and hype (intensity of coverage) over the 2013- 2021 period. Importantly, we find the topics differ not only in strength (significant vs. insignificant) but also in direction (negative vs. positive) and shape (linear vs. non-linear) of their relations to bitcoin returns, trading volume, and volatility.
