Supply Last Active
Tracks the percentage of supply last moved more than 1, 2, or 5+ years ago. Rising values indicate deep conviction holding.
What is it?
Supply Last Active segments supply based on each UTXO's last activity date, with fixed thresholds: 1 year, 2 years, 3 years, and 5 years+. Unlike HODL Waves which show all bands stacked, this metric allows precise tracking of specific thresholds. It is a conviction thermometer: the higher the proportion of supply unmoved for a long time, the more the network is in a retention phase.
How to read
Each line represents the percentage of total supply not moved for at least X years. When lines rise, supply is maturing - holders are not spending. When they fall, old coins are being put back into circulation. Crossovers between different threshold lines can mark behaviour changes at different time scales.
Key zones
Historically, when supply inactive for > 1 year exceeds 65%, this has marked advanced accumulation zones. The > 5 year threshold is a proxy for quasi-permanently withdrawn supply (lost coins + extreme HODLers), usually stable between 20-25% but with a secular upward trend.
What to observe
A decoupling between thresholds is informative: if > 1 year starts falling but > 3 years stays stable, only 'moderately old' coins are being spent - true long-term holders are holding. If all lines fall simultaneously, it is a stronger indication of widespread redistribution.
Historical context
Supply inactive for > 1 year exceeded 70% in December 2022, a historical record. This level had never been reached in previous cycles, even at the 2015 and 2018 troughs. This suggests a structural evolution in holder behaviour, potentially linked to the normalisation of Bitcoin as a reserve asset rather than a pure speculative instrument.
Expert notes
The secular upward trend of > 5 years necessarily includes Satoshi's coins (~1M BTC) and other likely lost coins. For a purer conviction analysis, it is preferable to look at intermediate bands (1-3 years) which are less contaminated by irrecoverable coins. Supply Last Active > 1 year is often used as a denominator in other metrics (Reserve Risk, Liveliness).
Common mistakes to avoid
Assuming that 'inactive supply = supply that will eventually be sold' is incorrect. A significant portion will never be spent. Also do not confuse this metric with exchange flows: a coin can be moved to a cold wallet (counted as 'active') without any intention to sell.
