Bitcoin’s on-chain activity reveals far more than just transaction volume—it offers deep insights into investor behavior, market cycles, and potential price turning points. One of the most powerful tools for visualizing this behavior is the HODL Waves chart. By analyzing how long Bitcoin has remained unmoved across wallets, HODL Waves provides a real-time pulse of market sentiment, helping investors distinguish between short-term speculation and long-term conviction.
This guide breaks down everything you need to know about HODL Waves—from how it works and what it reveals, to how traders and analysts use it to anticipate market shifts.
What Are HODL Waves?
HODL Waves is a blockchain-based visualization tool that categorizes Bitcoin’s circulating supply based on how long each coin has remained inactive in wallets. The term “HODL” originated from a misspelled “hold” in a 2013 Bitcoin forum post and has since become a cultural mantra for long-term Bitcoin holders.
The HODL Waves chart divides Bitcoin into age cohorts—ranging from coins moved within the last 24 hours to those untouched for over a decade. Each cohort is represented as a colored band, forming wave-like patterns that shift over time. These “waves” reflect changes in holding behavior across the network.

The Y-axis of the chart represents the percentage of total Bitcoin supply, always summing to 100%. This means at any given time, the chart shows the full distribution of Bitcoin by age—offering a clear picture of who is holding, who is selling, and what stage of the market cycle we might be in.
What Does HODL Waves Reveal About Market Behavior?
HODL Waves shines a light on the actions of different market participants. When younger cohorts (coins moved recently) grow rapidly, it often signals that older holders are selling—releasing long-dormant Bitcoin back into circulation.
Historically, such movements occur during major price rallies. As Bitcoin’s price surges, fear of missing out (FOMO) drives new investors into the market, while seasoned holders take profits. This dynamic is clearly visible on the chart: a spike in the “young” bands (typically shown in red or orange) often precedes a market top.
Conversely, when older cohorts expand—especially those holding coins for over a year—it suggests growing confidence and accumulation. These long-term holders, often referred to as "smart money," tend to buy during downturns and hold through volatility. Their behavior contrasts sharply with short-term traders who react emotionally to price swings.
A shrinking blue or purple band (representing 1+ year old coins) can be an early warning sign: if long-term holders are selling, the market may be nearing a peak.
How Is HODL Waves Calculated?
HODL Waves relies on on-chain analysis, a method of interpreting raw blockchain data to uncover economic patterns. The calculation focuses on UTXOs (Unspent Transaction Outputs)—the technical term for individual units of Bitcoin that haven’t been spent since their last transaction.
Each UTXO is timestamped based on when it was last moved. The HODL Waves model groups these UTXOs into age bands:
- 0–24 hours
- 1 day – 1 week
- 1 week – 1 month
- 1 month – 3 months
- 3 months – 6 months
- 6 months – 1 year
- 1 year – 2 years
- 2 years – 3 years
- 3 years – 5 years
- 5 years – 7 years
- 7 years – 10 years
- 10+ years
By tracking how the distribution across these bands evolves, analysts can detect macro-level shifts in holder behavior—such as mass selling after a bull run or silent accumulation during bear markets.
Practical Uses of the HODL Waves Chart
Identifying Market Cycles
HODL Waves acts as a behavioral compass through Bitcoin’s volatile cycles. During bull markets, younger bands expand as long-term holders cash out and new buyers enter. When these bands peak, it often coincides with price tops—followed by corrections as supply re-enters the market.
In bear markets, the opposite occurs: younger bands shrink as trading activity slows, while older bands grow as investors "hodl" through downturns. A sustained increase in the 1-year+ cohort is a strong signal of maturing confidence.
Spotting Smart Money Moves
Long-term holders are frequently seen as more informed due to their experience and strategic timing. When they begin selling—visible as a drop in older bands—it may indicate they perceive overvaluation. Conversely, accumulation in these bands suggests they see value at current prices.

Simplified Indicators: The 1-Year HODL Wave
Some analysts use a streamlined version: the 1-Year HODL Wave, which tracks only Bitcoin untouched for at least 12 months. This single metric often moves inversely to price—rising during dips and falling during rallies.
This inverse relationship reinforces the idea that long-term holders buy low and sell high. A sharp decline in the 1-year wave during a price surge can serve as a cautionary signal: the market may be overheating.
Who Created HODL Waves?
The HODL Waves concept was originally developed by Dhruv Jain (formerly Dhruv Bransal) of Unchained Capital in April 2018. His work helped popularize age-based UTXO analysis, making complex on-chain data accessible and actionable for everyday investors.
Since its introduction, HODL Waves has become a staple in crypto analytics platforms, used by traders, researchers, and institutions to assess market health and sentiment.

Frequently Asked Questions (FAQ)
What does "HODL" mean in HODL Waves?
"HODL" is a slang term derived from a typo of "hold," symbolizing the strategy of holding Bitcoin long-term regardless of price volatility. In HODL Waves, it refers to measuring how long coins have been held without movement.
Can HODL Waves predict Bitcoin price crashes?
While not a direct predictor, HODL Waves can signal increased risk. A sudden drop in long-held coins (e.g., 1-year+ cohort) during a price rally often precedes corrections, as it indicates profit-taking by experienced holders.
How often is HODL Waves data updated?
The data is updated in real time based on blockchain activity. As transactions occur and UTXOs are spent or created, the age distribution adjusts automatically.
Is HODL Waves reliable for investment decisions?
It should be used alongside other indicators. While highly informative about market behavior, it works best when combined with metrics like MVRV ratio, exchange flows, and hash rate trends.
What does a growing 1-year+ HODL wave indicate?
It suggests increasing confidence among long-term investors. When more Bitcoin is held for over a year, it often reflects accumulation during bearish periods and reduced selling pressure.
Are all old coins "safe" from selling?
Not necessarily. While older coins are less likely to move, major events (e.g., regulatory shifts or macroeconomic shocks) can trigger large sell-offs even from dormant wallets.

Final Thoughts
HODL Waves is more than just a colorful chart—it’s a window into the psychology of Bitcoin ownership. By revealing who’s holding, who’s selling, and for how long, it transforms raw blockchain data into actionable insights.
Whether you're a seasoned trader or a long-term investor, understanding HODL Waves empowers you to read market sentiment beyond price alone. As Bitcoin continues to mature, tools like this will play an increasingly vital role in navigating its cyclical nature with clarity and confidence.
