90D Coin Days Destroyed is the 90 day rolling sum of Coin Days Destroyed (CDD) and shows the amount of coin days that have been destroyed over the past year. This version is age-adjusted meaning that we normalize by time in order to account for the increasing baseline as time goes by.

This is the Point-in-Time (PiT) variant of 90D Coin Days Destroyed (CDD-90). 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.
