Rising long-term holder supply means coins are maturing past the cutoff and being held, while falling supply means older coins are being spent. The 155-day threshold is a convention, and coin age resets when coins move even between the same owner's wallets. # Long-Term Holder Supply: Formula, Meaning, Signals, Examples and How to Use It ## How Is Long-Term Holder Supply Calculated? The amount of circulating supply held by coins that have not moved for at least 155 days, a cutoff commonly used by data providers to separate long-term from short-term holders. **Formula:** `LTH supply = sum of unspent outputs whose age is at least 155 days` **Inputs:** - Unspent outputs with creation dates - Age threshold (commonly 155 days) - Circulating supply **Worked example.** If 16.6 million of 19.7 million coins are older than the cutoff (illustrative), long-term holders control 84.3% of supply. The inputs are illustrative numbers, not market data. **Reading it.** Rising long-term holder supply means coins are maturing past the cutoff and being held, while falling supply means older coins are being spent. Analysts follow it for signs of accumulation or distribution by experienced holders. **Limits.** The 155-day threshold is a convention, and coin age resets when coins move even between the same owner's wallets. Lost coins are included. ## What is Long-Term Holder Supply? The amount of circulating supply held by coins that have not moved for at least 155 days, a cutoff commonly used by data providers to separate long-term from short-term holders. ## How to use Long-Term Holder Supply Rising long-term holder supply means coins are maturing past the cutoff and being held, while falling supply means older coins are being spent. Analysts follow it for signs of accumulation or distribution by experienced holders. A reading alone is never a buy or sell signal; it needs context from price structure, volume, volatility and the broader market regime. ## Strengths - Summing unspent outputs above an age threshold gives a stock measure that does not depend on how many coins moved that day. - Pairing it with short-term supply covers the whole supply, so the two together describe the split by coin age. - Reproducible when the formula and data convention are fixed. ## Weaknesses and limitations - As coins age past 155 days they move into this group automatically, so supply can rise with no new buying by anyone. - The figure is in coins, so it does not reflect the price at which holders acquired them or whether they are in profit. - 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. Rising long-term holder supply means coins are maturing past the cutoff and being held, while falling supply means older coins are being spent. The 155-day threshold is a convention, and coin age resets when coins move even between the same owner's wallets. 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 Long-Term Holder Supply? Long-Term Holder Supply takes these inputs: unspent outputs with creation dates; age threshold (commonly 155 days); circulating supply. There is no universal best setting for the tunable ones, so test them across instruments, regimes and out-of-sample periods and favor stable parameter regions over one historical winner. Can Long-Term Holder Supply be used by itself? The 155-day threshold is a convention, and coin age resets when coins move even between the same owner's wallets. Lost coins are included. For that reason it is read next to measures of direction, participation, valuation, liquidity and risk, not alone. Does Long-Term Holder Supply work on every timeframe? The calculation (LTH supply = sum of unspent outputs whose age is at least 155 days) 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 Long-Term Holder Supply give false signals? As coins age past 155 days they move into this group automatically, so supply can rise with no new buying by anyone. The figure is in coins, so it does not reflect the price at which holders acquired them or whether they are in profit. Lag, noise and regime changes add to this, because market participants react to new information after the reading is calculated. How should Long-Term Holder Supply be backtested? Rebuild Long-Term Holder Supply 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.
