What is the DQYDJ Historical ROI Tool?

DQYDJ (Don't Quit Your Day Job) is a respected finance and data science blog. Their Bitcoin return calculator is a scholarly tool that uses high-quality historical data.

It is unique because it allows for inflation-adjusted (real) return calculations, giving investors a much clearer picture of purchasing power changes than nominal price charts.

Unique Data Insights

  • Inflation-adjusted (real) vs Nominal return toggles
  • Custom date range selection from Bitcoin's earliest days
  • Annualized return (CAGR) calculations for long-term holding
  • Comparison benchmarks against traditional finance indices
  • Visualized growth of a hypothetical starting investment

Usage Constraints

Focuses on historical data, not future price forecasting
Does not include daily-level trading PnL for active swing traders
Does not support altcoins (primarily BTC-focused)
Does not factor in individual custody or transaction costs
