Abstract

This study aims to analyze the impact of market sentiment on cryptocurrency price volatility, focusing on the top 50 cryptocurrencies by market capitalization in 2024. Data was collected from CoinMarketCap for the period 2021-2023, and market sentiment is measured using Natural Language Processing on text data from social media (Twitter, Reddit), forums, and news articles. The analysis employs Structural Equation Modeling - Partial Least Squares to examine the relationship between market sentiment and price volatility. The latent variable "Market Sentiment" is constructed using the NLP indicator, while "Price Volatility" is measured by daily standard deviations and the Average True Range. Additional factors, such as Layer-1, Layer-2, Decentralized Finance, Specialized Computing, Real World Assets, and Decentralized Infrastructure Projects, are also incorporated for a more comprehensive analysis. The results show that positive sentiment significantly increased price volatility, especially for speculative projects like Layer-2 and DeFi, while negative sentiment significantly reduced volatility. Neutral sentiment had no significant effect on price volatility. These findings highlight the important role of social media and news in driving sharp price movements in the cryptocurrency market, providing valuable insights for investors and policymakers in managing and responding to market sentiment.

Abstract

The purpose of this study is to investigate the effects of financial knowledge, financial attitudes, and personality on financial management behavior, with self-control serving as a mediating variable. The research focuses on employees of PT Bank KB Bukopin Banjarmasin, particularly in the context of post-merger performance challenges. This study seeks to fill the gap in previous research by integrating cognitive and psychological factors within a formal organizational setting. Using a quantitative explanatory approach, data were collected through a census of 75 permanent employees with a minimum of three years of service. The data were analyzed using Partial Least Squares Structural Equation Modeling to assess both direct and indirect effects among the variables. The findings indicate that FK, FA, personality, and SC significantly influence FMB. Notably, personality has the strongest effect on SC, while FK shows the most substantial direct influence on FMB. The model explains 50.8% of the variance in FMB, confirming SC as a key mediating variable. These results reinforce the Theory of Planned Behavior and suggest that improving financial literacy, fostering positive attitudes, and enhancing self-control are essential strategies for strengthening financial behavior among employees in banking institutions.
