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

Millennials shop for stylish items on Shopee, and this study analyzes how eWOM, brand image, and brand trust influence their purchasing choices. A total of 75 people participated in a survey-based quantitative analysis. SEM was utilized to analyze the data, along with SmartPLS. Based on the data, it is clear that a positive brand image and brand trust significantly influence purchasing choices, while negative eWOM has the opposite effect. The study shows that the level of consumer trust in the brand is the most important factor when making a purchase. With an R-squared value of 0.685, we can see that these three factors explain 68.5% of the variation in consumer purchases. This finding emphasizes the importance of actively managing eWOM, strengthening brand image through digital branding strategies, and increasing trust through service and transparency. This study concludes that digital marketing strategies that focus on brand reputation and customer satisfaction will have a positive impact on purchasing decisions and loyalty of millennial consumers in e-commerce.
