What is Bitcoin Currency?

₿C (₿C) is a unit of account derived from Bitcoin's entire USD price history. It is computed as the cumulative average of every daily Bitcoin price in dollars going back to the genesis block in 2009. Two monetary systems. One unit of account. No institution controls it. No one can change it. It is simply mathematics applied to the public record.

About the BTCADP

Methodology

Volume-Weighted Average Prices (VWAP) computed independently for each qualifying exchange, then aggregated using a 25% trimmed mean. Equal weighting of exchanges prevents volume fabrication from influencing the result.

Provisional Data

Current values are derived from aggregated public data sources, not from trade-level exchange data per the full specification. All values are flagged as provisional until verified through independent research.

Open Standard

The BTCADP belongs to no one. The specification is publicly available, and anyone can compute, verify, or improve upon these values. Read the full specification.

For Researchers

Interested in contributing to the project? We're looking for independent researchers to help verify historical data and stress-test the framework. Apply here.
