A Clearer View of Bitcoin’s Real-World Value

Truflation is introducing the Bitcoin Purchasing Power Index (TRUFBPPI) — a new metric designed to answer a practical question: What can your Bitcoin actually buy?

While most financial tools track Bitcoin in fiat terms, the TRUFBPPI offers a different perspective. It measures Bitcoin’s purchasing power against a global basket of 15 essential commodities, including energy, agriculture, and metals, providing a grounded view of BTC’s real economic utility.

🔍 What Is the TRUFBPPI?

The Bitcoin Purchasing Power Index tracks how much of a representative commodity basket can be bought with 1 BTC. Instead of measuring Bitcoin’s price in dollars, the index flips the lens — showing how Bitcoin stacks up against real-world goods.
