Unspent Transaction Output Age

Unspent transaction output age is a metric used to determine how long a specific amount of cryptocurrency has remained unmoved in a particular address. This data is the primary input for HODL wave analysis and provides a granular view of holder behavior.

By tracking the age of these outputs, analysts can determine the cost basis of long-term holders and identify potential supply resistance levels. When older outputs are moved, it often indicates a change in sentiment or a shift in the long-term investment thesis.

This metric is a powerful tool for fundamental analysis, helping to distinguish between speculative "hot" money and committed "cold" storage. It is essential for understanding the underlying distribution of wealth within a network.
