BTC Sentiment Change: Analyzing the Impact of Public Sentiment on Bitcoin Prices

Abstract
This paper explores the concept of sentiment analysis in the context of Bitcoin (BTC) and its impact on the cryptocurrency’s price movements. We investigate how public sentiment, derived from social media and news sources, correlates with changes in Bitcoin’s market value.

Introduction
Bitcoin, as the first and most well-known cryptocurrency, has experienced significant price volatility since its inception. One of the factors contributing to this volatility is the sentiment of the public towards Bitcoin. Sentiment analysis, a subfield of artificial intelligence, involves the computational study of people’s opinions, attitudes, and emotions expressed in text. This study aims to understand the relationship between sentiment changes and Bitcoin’s price fluctuations.

Literature Review
Previous studies have shown that social media sentiment can predict stock market movements. Extending this concept to cryptocurrencies, researchers have begun to analyze the sentiment of tweets, news articles, and forum discussions to predict price changes in Bitcoin. The literature suggests that positive sentiment is often associated with price increases, while negative sentiment is linked to price drops.

Methodology
Data Collection
We collected data from various sources including Twitter, Reddit, and financial news websites. Tweets and Reddit posts were filtered for Bitcoin-related content using keywords and hashtags. News articles were sourced from reputable financial publications.

Sentiment Analysis
Sentiment analysis was performed using Natural Language Processing (NLP) techniques. We employed machine learning algorithms to classify the sentiment of each piece of content as positive, negative, or neutral.

Correlation Analysis
We correlated the sentiment scores with historical Bitcoin price data to identify any patterns or correlations.

Results
Our findings indicate that there is a significant correlation between public sentiment and Bitcoin price changes. Positive sentiment periods are often followed by price increases, and vice versa. However, the relationship is not always direct, and other factors such as market manipulation and macroeconomic events also play a role.

Discussion
The results suggest that sentiment analysis could be a valuable tool for investors and traders in the cryptocurrency market. By monitoring public sentiment, they can potentially anticipate market movements and make informed decisions. However, it is crucial to consider sentiment analysis as one of many tools in the investment toolkit, not a standalone predictor of market behavior.

Conclusion
This study contributes to the growing body of research on the influence of public sentiment on cryptocurrency markets. While our findings are promising, further research is needed to refine sentiment analysis models and better understand the complex dynamics of the cryptocurrency market.
