Bitcoin Rate of Return (BRR) Redefining Investment Performance Metrics in an Era of Currency Debasement

This dataset supports the study “Bitcoin Rate of Return (BRR): Redefining Investment Performance Metrics in an Era of Currency Debasement.” It provides comparative time-series and indexed data evaluating the performance of the S&P 500 and other traditional investment assets in both U.S. dollar (USD) and Bitcoin (BTC) terms. The data is designed to illustrate how conventional investment metrics—such as Internal Rate of Return (IRR), Return on Investment (ROI), and Compound Annual Growth Rate (CAGR)—can diverge significantly from real performance when measured against a non-inflationary benchmark like Bitcoin.

The dataset contains indexed values, percentage changes, and compound annual growth rates (CAGR) for the S&P 500 across different time periods (2016–2025 and 2020–2025). Each table contrasts nominal performance (USD terms) with real performance (BTC terms) to highlight the effects of monetary debasement on asset valuation.
