Binary Coin Days Destroyed (Binary CDD) is computed by thresholding Adjusted CDD by its average over time, i.e. taking the mean destruction over time and asking whether there were more Adjusted CDDs destroyed today than on average. Binary CDD is used in order to minimize the impact of exchange movements, which do not accurately reflect behavior of the long-term holders. This metric was developed by Hans Hauge and Ikigai. For more information see this post.

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.
