Abstract

This study analyzes the relationship between public sentiment on the social media platform X and Bitcoin's global price volatility from January to October 2024. Using sentiment analysis supported by the BERT machine learning model and the Support Vector Machine (SVM) algorithm, relevant tweets were classified into positive, neutral, and negative sentiments. Model evaluation demonstrated excellent performance, with precision, recall, and F1-score for positive sentiment reaching 95.52%, 93.57%, and 94.53%, respectively. Neutral sentiment achieved precision of 88.61%, recall of 92.11%, and an F1-score of 90.32%. Negative sentiment yielded precision of 92.02%, recall of 91.05%, and an F1-score of 91.53%. The results indicate a significant correlation between public sentiment and Bitcoin price movements, where positive sentiment drives price increases while negative sentiment often triggers sell-offs. Moreover, the intensity of social media discussions significantly impacts market dynamics, as evidenced by a spike in activity in March 2024 coinciding with Bitcoin's price peak during the study period. These findings provide insights for investors, market analysts, and regulators to understand the role of social media as a market sentiment indicator influencing digital asset volatility.

Abstract

This research explores how changes in bank interest rates affected home sales in Indonesia, both before and after the Covid-19 pandemic, placing importance on the connection between interest rate changes and the real estate market's behavior. A quantitative analysis of data regarding interest rates, volumes of home sales, and relevant economic indicators shows that notable interest rate decreases before the pandemic generally aligned with an increase in home sales, which reflects the usual housing market reaction to more accessible financing. Post-pandemic, the analysis indicates a more complex interaction. Even with sustained low-interest rates, home sales saw a substantial decrease, likely due to increased economic uncertainty and shifting consumer preferences, in most cases influenced by the pandemic. These observations emphasize the importance of grasping market sentiment and purchasing behaviors, suggesting that healthcare crises can significantly alter economic activities, like real estate. Furthermore, the implications extend beyond real estate, advising policymakers and financial institutions to develop interest rate strategies that consider the changing landscape of consumer behavior in health-related crises. The study ultimately provides important insights into the housing market's resilience during external shocks and the role of financial policies in supporting economic stability amidst public health emergencies, therefore guiding effective economic recovery efforts.
