The objective of this research article is to consolidate existing literature in the field of sentiments and cryptocurrency through a systematic literature review (SLR) by adopting the SPAR-4-SLR protocol and establishing a structured foundation for future studies. The study includes 42 research articles from the SCOPUS and WoS databases. The SLR offers several findings. First, research in the field of sentiment and cryptocurrency has surged in the recent past and the area is still young to research. Second, the study sheds light on major contributors to the field of study. Third, sentiment has proved to be a major predictor of cryptocurrency due to its characteristics. Finally, the study’s findings reveal a range of sentiment measure indicators in the literature and shed light on the influential role of sentiments in cryptocurrency prices, returns, and volatility. In the absence of systematic reviews in the field, this article makes a significant contribution.
