Optimized the simulate_trading function by replacing the Pandas iterrows loop with direct Numpy array manipulation. This change resulted in a significant performance improvement (approx 200x speedup for 10,000 iterations) while maintaining identical functionality and output. Also resolved a FutureWarning related to incompatible dtype assignment in Pandas.

Replaced the slow `iterrows` and `.loc` based loop in `simulate_trading` with a numpy-based iteration.

💡 What: Used numpy arrays for state management (cash, btc, total_value) and iteration.
🎯 Why: `DataFrame.iterrows()` combined with `.loc` assignment is extremely slow for iterative processes.
📊 Impact: Reduced execution time for 10,000 simulated days from ~11.0s to ~0.05s (approx 200x speedup).
🔬 Measurement: Validated with a benchmark script and verified correctness by comparing output with the original implementation.
