Definition. Binary Coin Days Destroyed (Binary CDD) is the regime-flag transform of Supply-Adjusted CDD, computed by thresholding Adjusted CDD against its long-run average, asking whether more Adjusted CDDs were destroyed today than on average.

Technical. Thresholding against the long-run mean minimizes the impact of exchange movements, which do not accurately reflect long-term holder behavior.

Interpretation. Readings of 1 mark days of above-average lifespan destruction, readings of 0 mark days of below-average lifespan destruction.

Notes. Developed by Hans Hauge and Ikigai. For more information, see the post on Bitcoin days destroyed.

This is the Point-in-Time (PiT) variant of Binary CDD. PiT metrics are strictly append-only and their history is immutable. The historic data does not necessarily reflect the best current knowledge, but the information at the time when a data point was first computed. PiT metrics are ideal candidates for applications in model backtesting and related quantitative purposes. Read our article on PiT metrics for more information.
