Bundle of all active supply age bands, aka HODL waves. Each colored band shows the percentage of BTC in existence that was last moved within the time period denoted in the legend. The concept of HODL waves was first described in this post by Unchained Capital.

This is the Point-in-Time (PiT) variant of HODL Waves. 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.
