文摘In this paper,we analyze the time-series graphs of Bitcoin price and Twitter-based economic uncertainty index over the past two years and use a wavelet coherence graph to determine their relationship.We found a causal relationship between Bitcoin(BTC)and Twitter-based economic uncertainty(TEU)index in different frequency bands,which would help predict Bitcoin price movements in the future.Our study provides reference to academics and investors.
