# MSOL (Median Spent Output Lifespan)

MSOL (Median Spent Output Lifespan) is the median age (in days) of all spent transaction outputs.

# Indicator Overview

MSOL (Median Spent Output Lifespan) is the median age (in days) of all spent transaction outputs. This indicator, along with ASOL, highlights (on a macro level) how many days coins were held before being moved, giving insight into short-term and long-term HODLer movements.

It should be noted that, in order to account for change and eliminate obvious relay transactions, outputs with a lifespan of less than 1 hour are discarded.

# How is it measured?

MSOL (Median Spent Output Lifespan) is defined as the median age (in days) of all spent transaction outputs in a given time period.

$\textrm{MSOL} = \textrm{Median}\big\{ \textrm{lifespan}~{\color{gray}{\textrm{[days]}}} ~{\color{gray}{\textrm{(of all spent outputs)}}} \big\}$
