Direct Answer
Long-Term Holder Supply is the portion of a crypto asset's circulating supply held by wallets whose coins last moved on-chain roughly 155 days ago or longer. It is an on-chain, coin-age-based metric used to estimate how much of the current supply is held by conviction-driven owners rather than recent buyers, which matters because long-term holders are statistically far less likely to sell in response to short-term price volatility.
Key Takeaways
- Long-Term Holder (LTH) Supply is the sum of coin units that have sat unmoved on-chain for roughly 155 days or more.
- It is the complement of Short-Term Holder (STH) Supply, which covers coins that moved more recently.
- The 155-day cutoff comes from empirical Bitcoin holder-behavior research, not a fixed protocol rule, and can be approximated differently across data providers.
- LTH Supply is typically expressed both as an absolute coin count and as a percentage of total circulating supply.
- A rising LTH Supply generally reflects accumulation and reduced available sell-side supply; a falling LTH Supply reflects distribution.
- Coins reclassify automatically from short-term to long-term once they cross the age threshold - no holder action is required.
- Spending a coin (moving it on-chain) resets its age clock, immediately reclassifying it back to short-term supply.
- The metric is derived from UTXO or address-cohort age-tracking and is most mature for Bitcoin, with adapted methodologies used for some other UTXO-based or account-based chains.
How Is Long-Term Holder Supply Calculated?
Rather than deriving from price or volume, Long-Term Holder Supply comes directly from how long each coin has sat untouched on-chain - the qualifying age threshold is what separates conviction-driven holders from the rest of supply. The general methodology is:
LTH Supply = Σ (coin units whose last on-chain move occurred ≥ ~155 days ago)
The dividing line is what counts as "held": an on-chain data provider tracks every unspent transaction output (UTXO) - for account-based chains, an analogous cohort-based approximation is used - and records the timestamp of the last time each unit of the asset moved between addresses. Once a coin has gone roughly 155 days (sometimes implemented as a fixed 150-155-day rolling window depending on the provider) without moving, it crosses into the long-term bucket and stays there until it's spent again - a threshold chosen because that's roughly where statistical conviction, rather than short-term price memory, starts to show up in holder behavior. Everything below that threshold is summed into Short-Term Holder Supply instead. Because every unit of supply falls into exactly one bucket at any given time, the two figures always add up to total circulating supply:
LTH Supply + STH Supply = Circulating Supply
Long-Term Holder Supply is most often read as a percentage of circulating supply (LTH Supply ÷ Circulating Supply × 100), which makes accumulation or distribution trends comparable across time even as total supply grows.
A Simple Illustration
Consider a hypothetical asset with 20 million coins in circulating supply. Suppose an on-chain data provider's age-band breakdown shows 15.5 million coins that have sat unmoved for 155 days or more, and the remaining 4.5 million coins moved more recently than that. In this hypothetical scenario, Long-Term Holder Supply would be 15.5 million coins, or 77.5% of circulating supply (15.5M ÷ 20M × 100).
If, over the following months, a sustained rally leads a meaningful share of those long-held coins to finally move on-chain - sold or transferred to new buyers - LTH Supply would fall as those units reclassify into short-term holder supply, even though total circulating supply hasn't changed. A steady decline in LTH Supply during a price advance is one pattern analysts associate with a distribution phase. These figures are illustrative only; for real, current values, consult an on-chain analytics provider's published dashboards or API (see References below), since Swoopr does not publish live on-chain data on this page.
Why Long-Term Holder Supply Matters
Long-Term Holder Supply is used as a proxy for available sell-side supply and market conviction. Because coins held for many months tend to belong to owners who have already sat through prior drawdowns without selling, this cohort is statistically less reactive to short-term price swings than recent buyers. A high or rising LTH Supply is often read as a sign of accumulation and reduced circulating supply available to sell, which some analysts associate with tightening supply dynamics. A falling LTH Supply, particularly during a rally, is often read as distribution - long-term holders moving coins to newer, more reactive market participants.
LTH Supply is typically read alongside LTH realized price (the average acquisition price of that cohort) and LTH profit/loss ratios to see whether long-term holders are sitting on large unrealized gains, which can precede periods of elevated distribution as some choose to realize profit. No single reading of LTH Supply in isolation predicts price direction; it is one input among several holder-behavior metrics used to gauge market cycle stage.
Limitations and Common Mistakes
- Methodology differences across providers. The exact age threshold and whether it is a hard cutoff or a probabilistic band varies by data source, so LTH Supply figures are not always directly comparable between platforms.
- Coin movement doesn't always mean a sale. Internal wallet consolidation, custodial migration, or collateral posting can reset a coin's age and shift it out of the long-term bucket without any actual selling occurring.
- Best developed for Bitcoin and other UTXO-based chains. Account-based chains require adapted cohort methodologies that are less standardized and less battle-tested.
- Not a standalone trading signal. LTH Supply describes holder composition, not price direction - it needs to be combined with realized price, profit/loss data, and broader market context.
- Custodial and exchange wallets blur the picture. Coins held on behalf of many end users in a single exchange or custody wallet are tracked as one entity's age profile, obscuring the actual holding periods of the underlying owners.
Frequently Asked Questions
What counts as a long-term holder?
Most on-chain analytics providers classify a unit of a coin as long-term-held once the wallet holding it has held it for roughly 155 days or more since it last moved on-chain. Before crossing that threshold, the same coin counts as short-term holder supply. The exact cutoff and methodology can vary slightly by data provider, and moving a coin resets its age clock regardless of how long it was previously held.
Why is 155 days used as the threshold for long-term holders?
The roughly 155-day mark comes from empirical research into historical Bitcoin holder behavior: coins that remain unmoved past that point are statistically held by owners who are much less likely to sell in response to short-term price swings. Researchers (originally Glassnode and Unchained Capital, building on earlier coin-age work) adopted it as the dividing line between reactive short-term holders and conviction-driven long-term holders.
Does falling Long-Term Holder Supply always mean holders are selling into a top?
Not necessarily. Falling LTH Supply means previously long-held coins moved on-chain, which is often read as distribution during a rally, but it can also reflect collateral posting, custody migration, or wallet consolidation that doesn't represent an actual sale. It's typically read alongside price trend, exchange inflow data, and LTH profit/loss ratios rather than as a standalone signal.
How is Long-Term Holder Supply different from a fixed supply cap?
A fixed supply cap, like Bitcoin's 21 million coin limit, is a protocol-enforced maximum on total issuance and doesn't change based on behavior. Long-Term Holder Supply is a behavioral, moving classification within that total supply - coins continuously shift between the short-term and long-term buckets as they age or get spent, with no cap on how much of circulating supply can be long-term-held at any given time.
Does the long-term holder classification apply to a coin or to an address?
To the coin, in the standard construction. Each unit of supply is classified by how long it has been since it last moved, so one address can hold some supply classified as long-term and some as short-term at the same time. This is why the metric is not a count of investors and why it says nothing about whether a given holder is patient. It is a statement about the age distribution of supply, described using language that implies something about people.
What happens when a long-term holder moves coins between their own addresses?
The coins are reclassified as short-term, because the metric sees a movement and has no way to know both addresses belong to one party. A holder reorganising storage, changing custody arrangement or upgrading their wallet setup therefore appears in the data as long-term supply converting to short-term supply, which is the same signature that distribution produces. Entity-adjusted versions attempt to filter these, at the cost of depending on clustering heuristics.
Why does long-term holder supply rise mechanically after heavy buying?
Because supply that changed hands during a period of heavy activity ages together. Coins bought and moved on chain during an active stretch are all classified as short-term at that time, and if they are not moved again they cross the age threshold together some months later. That produces a step increase in long-term holder supply with no decision made by anyone at that moment. Dating such a rise back to the buying that caused it is what separates the mechanical component from genuine holding behaviour.
Is the age threshold a hard cut or a smoothed transition?
Both approaches are used. A hard cut assigns every coin to one side of the boundary, which is simple and produces step behaviour as cohorts cross it. Some providers instead apply a weighting that transitions gradually across a range of ages, on the reasoning that the probability of a coin moving declines smoothly rather than at a single point. The two produce visibly different series, particularly around periods when a large cohort crosses, so the construction should be checked before series are compared.
How does long-term holder supply relate to illiquid supply?
They are different attempts at the same idea. Long-term holder supply classifies by how long coins have sat unmoved. Illiquid supply classifies by the observed spending behaviour of the entities holding the coins, grouping addresses by the proportion of what they receive that they subsequently spend. The second requires entity clustering and behavioural scoring, so it is more modelled and less reproducible, while the first depends only on a threshold. Neither measures how much supply would actually be offered at a given price.
