SOAB (Spent Output Age Bands) is a bundle of all spent outputs that were created within a specified age band. Each band represents the percentage of spent outputs that were created within the time period denoted in the legend.
As such, SOAB gives detailed insights into the relative age of spent outputs, demonstrating the age of coins that are moving, and thereby highlighting whether market movements are being caused by long-term HODLers or newer market participants.
Spent output age bands are measured by calculating the age of coins that have been transacted within the specified time window.
SOAB aggregates and stacks the following age bands:
