This chart presents the average Lifespan held per coin (the age of the average HODL wave). It is based upon the following principles:

• Lifespan is a measurement of either the time since a coin was last moved (unspent coins), or the expended time when a coin is moved (spent coins).

• Each unit of coin in the supply creates an equivalent volume of coindays per day.

• Some portion of the coin supply is spent each day, destroying the accumulated coindays (called Coindays Destroyed, CDD)

• The remaining non-destroyed coindays can be aggregated, and then divided by the Circulating Supply to obtain the average Lifespan per coin.
