The 155-day threshold separates long-term holders from short-term speculators. ## Key points - The 155-day threshold separates Bitcoin supply into long-term and short-term holders based on the time since coins last moved. - HODL Waves visualize the aging of the Bitcoin supply, showing how coins transition between different age bands over time. - Long-term holder supply typically increases during market drawdowns and decreases during rapid price rallies. - Realized price metrics calculate the average acquisition cost for both cohorts, indicating aggregate profitability or loss. - Lost coins are permanently counted as long-term holder supply because they never move on-chain. In Bitcoin network analysis, analysts categorize the available supply based on the time elapsed since each coin was last transferred. The industry standard divides this supply into long-term and short-term holdings using a 155-day threshold, which allows observers to quantify accumulation by established investors and distribution to new market entrants. By examining the public blockchain, analysts can read the collective behavior of the market without relying on traditional exchange volume. ## The 155-Day Threshold The foundation of supply categorization in $BTC is the **155-day threshold**. Analysts determined this specific timeframe by analyzing the probability of a coin moving based on its dormancy. Statistical models of the Bitcoin network indicate that once a coin has remained unspent for 155 days (approximately five months), the statistical likelihood of it being spent in the near future drops significantly. Coins that have not moved in 155 days are classified as **Long-Term Holder (LTH)** supply. Coins that have moved more recently fall into the **Short-Term Holder (STH)** supply. This binary classification provides a framework for analyzing market cycles. The short-term holder cohort typically represents newer market participants, day traders, and speculators who are highly responsive to price volatility. The long-term holder cohort generally represents entities with higher conviction, such as early adopters, mining operations, and institutions holding the asset as a store of value. For example, if an investor purchases 10 BTC and withdraws it to a cold storage wallet on Jan. 1, those coins enter the short-term holder supply. If the coins remain in that exact wallet address without moving, they will transition into the long-term holder supply in early June. If the investor transfers even a fraction of those coins to a new address on day 154, the timer for that specific fraction resets to zero. ## HODL Waves and Coin Dormancy To visualize the aging of the coin supply, analysts utilize a metric known as **HODL Waves**. A HODL Wave chart groups the total circulating supply into age bands, such as 1 day to 1 week, 1 week to 1 month, 1 month to 3 months, and extending up to multiple years. When coins are held without moving, the older age bands on the HODL Wave chart expand, indicating that the supply is aging and becoming dormant. Conversely, when long-dormant coins are spent, they immediately re-enter the youngest age band (0 to 24 hours), causing a contraction in the older bands. This transition from older bands to the newest band is often referred to as coin destruction, though the coins themselves are not destroyed; rather, their accumulated dormant lifespan is reset. Tracking these waves allows analysts to observe macro shifts in holding behavior. Historically, older age bands swell during extended market drawdowns as investors refuse to sell at lower valuations. The same bands typically contract sharply during rapid price appreciation, as long-term holders transfer coins to exchanges to secure profits.

During accumulation phases, which often coincide with market bottoms and extended periods of price consolidation, the short-term holder supply decreases while the long-term holder supply increases. Coins flow from newer, easily panicked buyers to older, price-insensitive hands. The total proportion of the network's wealth held by the LTH cohort typically reaches its peak immediately before a new market expansion. During distribution phases, which usually occur during rapid price rallies, the dynamic reverses. As prices rise to new highs, long-term holders begin transferring their accumulated holdings to newer market participants who are entering the market due to momentum. The LTH supply declines as coins are sold, and the STH supply expands to absorb the incoming volume. Reports like [CryptoQuant Flags Dormancy in Older Bitcoin as Long-Term Selling Slows](https://basisdesk.news/news/bitcoin-onchain-dormancy-long-term-holder-selling-cryptoquant) often highlight the tail end of these distribution cycles when selling pressure from older hands finally exhausts itself. ## The Role of Profitability Metrics Analysts do not just measure the volume of coins held by these cohorts; they also measure the profitability of those coins. By checking the price of Bitcoin at the exact moment a coin was last moved on-chain, analysts can determine the **Realized Price** or average acquisition cost for both cohorts. The LTH realized price is typically lower and less volatile than the STH realized price, reflecting coins acquired months or years in the past. Comparing the spot price of Bitcoin to these realized prices yields a profitability multiple. When the spot price falls below the STH realized price, short-term holders are holding their coins at an aggregate loss, a condition that frequently leads to capitulation selling. If the spot price falls below the LTH realized price, it signals extreme market distress, a rare occurrence historically associated with generational market bottoms. ## Calculating the Transition Rate To understand the magnitude of supply aging, consider a simplified network model. Suppose the total circulating supply is 19,000,000 BTC. Assume 13,000,000 BTC is classified as LTH supply and 6,000,000 BTC is classified as STH supply. Over the next 30 days, exactly 500,000 BTC that was acquired five months prior crosses the 155-day threshold without moving. Concurrently, long-term holders transfer 100,000 BTC to exchanges to be sold. The net change to the LTH supply is the addition of the maturing 500,000 BTC minus the 100,000 BTC that was spent, resulting in a net increase of 400,000 BTC. The LTH supply grows to 13,400,000 BTC, while the STH supply shrinks to 5,600,000 BTC, indicating a strong accumulation phase where coins are aging faster than they are being distributed. ## Common Misconceptions * **Exchange Wallets Skew Data:** Moving coins between internal wallets does not necessarily indicate selling. Exchanges frequently consolidate user deposits into cold storage, which registers on-chain as a transfer and resets the coin age, even if the underlying beneficial owner has not sold the asset. Analysts must use clustering algorithms to filter out known exchange internal transfers to maintain data accuracy. * **Lost Coins Falsely Inflate LTH Supply:** A portion of the long-term holder supply consists of coins whose private keys are permanently lost. While these coins are technically classified as long-term holdings due to their age, they are practically removed from the liquid supply and will never be distributed, regardless of price action. * **Long-Term Holders Are Always Profitable:** The 155-day threshold is purely a measure of time, not profitability. An investor who purchased Bitcoin at the peak of a market cycle and holds for five months into a severe bear market will transition into the long-term holder cohort while carrying a significant unrealized loss. ## How This Connects to the Market Monitoring the balance between long-term and short-term holder supply provides a framework for assessing market risk and cyclical positioning. When the long-term holder supply is heavily depleted and short-term holder supply is highly inflated, it indicates that seasoned investors have largely exited their positions, leaving the market saturated with newer, less resilient capital. Conversely, when long-term holders dominate the supply, the liquid inventory available for purchase is constrained. This dynamic is foundational to on-chain analysis and influences how institutions view Bitcoin's liquidity profile. As new financial products emerge, analyzing which cohort is supplying the necessary liquidity becomes critical to market structure. ## FAQ **Why is 155 days used as the threshold?** Statistical analysis of the Bitcoin blockchain shows that once a coin has not moved for 155 days, the probability of it being spent in the near future drops significantly. **Do HODL Waves show when individual investors buy and sell?** No, HODL waves track the movement of unspent transaction outputs (UTXOs) on the blockchain in aggregate, not the identities of individual investors. **How do exchanges affect short-term supply metrics?** When exchanges move user funds into internal cold storage, the transaction resets the coin age on-chain, moving those coins into the short-term holder category unless analysts filter out known exchange addresses. **What is realized price in on-chain analysis?** Realized price calculates the average value of all coins based on the market price at the exact moment each coin last moved, rather than the current spot price. ## Sources 1.
