The total supply held by illiquid, liquid, and highly liquid entities. The liquidity of an entity is defined as the ratio of cumulative outflows and cumulative inflows over the entity's lifespan. An entity is considered to be illiquid / liquid / highly liquid if its liquidity L is ≲ 0.25 / 0.25 ≲ L ≲ 0.75 / 0.75 ≲ L, respectively. For more information see our introductory article on Bitcoin liquidity.

This is the Point-in-Time (PiT) variant of Liquid and Illiquid Supply. 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.
