BTC Sentiment Movement: Analyzing the Impact of Public Sentiment on Bitcoin Price Fluctuations

Abstract
This paper explores the correlation between public sentiment and the price movements of Bitcoin (BTC). Utilizing advanced sentiment analysis techniques and machine learning models, we aim to understand how market sentiment influences the cryptocurrency market, specifically focusing on Bitcoin.

Introduction
Bitcoin, as the first and most prominent cryptocurrency, has experienced significant price volatility since its inception. While various factors contribute to these fluctuations, public sentiment is often cited as a key driver. This study seeks to quantify this relationship by analyzing social media data, news articles, and other online sources to gauge public sentiment towards Bitcoin and correlating it with its price movements.

Methodology
Data Collection
We collected data from multiple sources including social media platforms (Twitter, Reddit), financial news websites, and Bitcoin forums. The data was collected over a period of one year, ensuring a comprehensive dataset for analysis.

Sentiment Analysis
Using natural language processing (NLP) techniques, we classified the sentiment of each data point as positive, negative, or neutral. Advanced algorithms were employed to handle sarcasm, irony, and other nuances in human language.

Machine Learning Models
We utilized various machine learning models such as regression analysis, decision trees, and neural networks to predict Bitcoin price movements based on sentiment scores. These models were trained and tested on our dataset to evaluate their accuracy.

Results
Our analysis revealed a strong correlation between positive sentiment and upward price movements in Bitcoin. Conversely, negative sentiment was often associated with price declines. However, the relationship was not always linear, with some instances of positive sentiment preceding price drops and vice versa.

Model Performance
The machine learning models showed varying degrees of success in predicting price movements based on sentiment. The neural network model performed the best, with an accuracy rate of 70% in predicting short-term price trends.

Discussion
The findings of this study highlight the significant role of public sentiment in influencing Bitcoin’s price. While our models were able to predict short-term trends with reasonable accuracy, the complex and often unpredictable nature of market sentiment suggests that long-term predictions remain challenging.

Conclusion
This research underscores the importance of sentiment analysis in understanding and predicting cryptocurrency market dynamics. As the field of sentiment analysis continues to evolve, its potential applications in financial markets, particularly in the context of cryptocurrencies, are vast. Future research should focus on refining these models and exploring their applicability in real-time trading scenarios.
