Abstract
This study leverages machine learning techniques to predict Bitcoin prices, addressing its inherent volatility for informed investment decisions. By categorizing data into daily prices and high-frequency 5-minute intervals, we employ:
- High-dimensional features for daily price analysis
- Fundamental trading features for 5-minute interval predictions
Key findings:
✅ Logistic Regression achieves 64.84% accuracy for daily prices
✅ XGBoost reaches 59.4% accuracy for 5-minute intervals
👉 Discover how machine learning transforms crypto forecasting

FAQ Section
Q1: Why is Bitcoin price prediction challenging?
A: Bitcoin's extreme volatility and sensitivity to external factors (e.g., regulations, market sentiment) require advanced modeling beyond traditional financial assets.
Q2: Which model performs best for short-term trading?
A: XGBoost outperforms others in 5-minute intervals (59.4% accuracy), likely due to its ability to handle nonlinear relationships in high-frequency data.
Q3: How can investors apply these findings?
A: Combine machine learning predictions with risk management strategies, especially when leveraging high-frequency trading signals.
