It isolates the most dormant part of supply, which includes deeply held and possibly lost coins. A high or rising share indicates a large dormant core of supply that is not available to trade. # Supply Last Active 2+ Years: Formula, Meaning, Signals, Examples and How to Use It ## How Is Supply Last Active 2+ Years Calculated? The share (or amount) of circulating supply that has not moved on-chain for at least two years. It isolates the most dormant part of supply, which includes deeply held and possibly lost coins. **Formula:** `Supply last active 2+ years = coins in unspent outputs aged at least 2 years / total circulating supply` **Inputs:** - Unspent outputs with creation dates - Two-year age cutoff - Circulating supply **Worked example.** If 4.2 million of 19.7 million coins have been unmoved for two years or more (illustrative), the share is 21.3%. The inputs are illustrative numbers, not market data. **Reading it.** A high or rising share indicates a large dormant core of supply that is not available to trade. A sharp drop means a large amount of very old coins moved, which analysts watch closely. **Limits.** It cannot separate deliberate long-term holding from coins that are lost, and the age resets with any movement. The two-year cutoff is a convention. ## What is Supply Last Active 2+ Years? The share (or amount) of circulating supply that has not moved on-chain for at least two years. It isolates the most dormant part of supply, which includes deeply held and possibly lost coins. ## How to use Supply Last Active 2+ Years A high or rising share indicates a large dormant core of supply that is not available to trade. A sharp drop means a large amount of very old coins moved, which analysts watch closely. A reading alone is never a buy or sell signal; it needs context from price structure, volume, volatility and the broader market regime. ## Strengths - A two-year threshold isolates a deeper layer of dormancy than the one-year measure, so the two together show nested bands. - Because the cutoff is high, the measure changes slowly and shows structural shifts rather than daily noise. - Reproducible when the formula and data convention are fixed. ## Weaknesses and limitations - Because the band is narrow in time, a small number of large old holdings moving can account for much of a day's change. - The band's share rises mechanically as past coins reach age two, so it carries the imprint of accumulation from two years earlier. - Correlated indicators can create false confidence by repeating the same underlying information. ## Editorial and risk note This page is educational content, not individualized investment advice.

No. A high or rising share indicates a large dormant core of supply that is not available to trade. It cannot separate deliberate long-term holding from coins that are lost, and the age resets with any movement. A trade built on it still needs a trigger, an invalidation rule, a position size and realistic execution assumptions. What is the best setting for Supply Last Active 2+ Years? Supply Last Active 2+ Years is computed from unspent outputs with creation dates; two-year age cutoff; circulating supply, so the choices that matter are the data convention and the window it is read over. Test those across instruments, regimes and out-of-sample periods instead of fitting one historical winner. Can Supply Last Active 2+ Years be used by itself? It cannot separate deliberate long-term holding from coins that are lost, and the age resets with any movement. The two-year cutoff is a convention. For that reason it is read next to measures of direction, participation, valuation, liquidity and risk, not alone. Does Supply Last Active 2+ Years work on every timeframe? The calculation (Supply last active 2+ years = coins in unspent outputs aged at least 2 years / total circulating supply) can be run on any bar size, but behavior is not portable: a reading on a five-minute chart describes a very different market window from the same reading on a daily chart. Validate the exact timeframe before relying on it. Why does Supply Last Active 2+ Years give false signals? Because the band is narrow in time, a small number of large old holdings moving can account for much of a day's change. The band's share rises mechanically as past coins reach age two, so it carries the imprint of accumulation from two years earlier. Lag, noise and regime changes add to this, because market participants react to new information after the reading is calculated. How should Supply Last Active 2+ Years be backtested? Rebuild Supply Last Active 2+ Years from unspent outputs with creation dates using point-in-time data, write the rules before testing, include delisted securities where relevant, model realistic fills and costs, reserve a validation sample and compare with a simpler baseline.
