Bitcoin's illiquid supply has surged past 14 million BTC, reaching an all-time high of 14.37 million BTC in early 2025—up from 13.9 million at the start of the year. This increase of 470,000 BTC underscores a powerful and growing trend among investors: holding rather than trading. According to on-chain analytics firm Glassnode, this shift reflects deepening confidence in Bitcoin as a long-term store of value.
With Bitcoin’s current circulating supply at approximately 19.8 million BTC, the fact that over 72% is now classified as illiquid highlights a fundamental transformation in market behavior. This structural change has profound implications for liquidity, market sentiment, and potential future price movements.
Understanding Bitcoin’s Illiquid Supply
The illiquid supply refers to Bitcoin that is highly unlikely to be sold in the short term. This includes coins held by long-term investors (often called "HODLers"), those stored in cold wallets, and balances that haven’t moved in years. These coins are effectively removed from active circulation, reducing the amount available for trading on exchanges.
Conversely, the liquid supply—estimated at just 5.4 million BTC—represents coins that are actively traded or readily available for sale. As more investors choose to hold rather than trade, this liquid portion continues to shrink, tightening market availability.

This growing imbalance between liquid and illiquid supply suggests a maturing ecosystem, where Bitcoin is increasingly viewed not as a speculative asset but as digital gold—a durable and scarce asset for wealth preservation.
Why the Shift Toward HODLing Matters
The rise in illiquid supply is more than just a statistical trend—it’s a behavioral signal. When investors hold Bitcoin for extended periods, it indicates strong conviction in its long-term value. This behavior is often amplified during periods of macroeconomic uncertainty, regulatory clarity, or institutional adoption.
Glassnode’s data reveals that this HODL trend has accelerated in 2025, coinciding with several key developments:
- The post-halving supply squeeze, where new Bitcoin issuance dropped to 3.125 BTC per block.
- Increased adoption by institutional custodians and retirement funds.
- Growing integration of Bitcoin into global financial infrastructure.
These factors collectively contribute to a reduction in sell pressure, which historically has preceded significant price appreciation. When supply dwindles and demand remains steady—or increases—it creates ideal conditions for upward price momentum.
The Risk of Supply Shock
One of the most critical implications of rising illiquidity is the potential for a supply shock. A supply shock occurs when the available pool of tradable Bitcoin shrinks faster than demand grows, leading to sharp price increases.
Historically, similar patterns emerged in the years following previous halvings (2012, 2016, 2020), when long-term holders accumulated aggressively while new supply slowed. In each case, this culminated in bull markets driven by scarcity dynamics.
With over 14 million BTC now out of circulation, the market is entering uncharted territory. If demand from retail and institutional buyers continues to rise while the liquid supply contracts, even small buying surges could trigger disproportionate price responses.
Market Sentiment and Strategic Implications
The persistent rise in illiquid supply serves as a real-time barometer of market confidence. Unlike sentiment surveys or social media metrics, on-chain data like this provides objective evidence of investor behavior.
Key insights derived from this trend include:
- Reduced volatility over time: As more coins are locked away, short-term price swings tend to diminish.
- Stronger resistance to sell-offs: During market corrections, long-term holders are less likely to panic-sell.
- Increased scarcity premium: With fewer coins available for purchase, each remaining BTC may command a higher price.
This evolution positions Bitcoin not only as a speculative asset but as a strategic reserve asset, akin to gold or other hard assets used in portfolio diversification.

FAQ: Understanding Bitcoin’s Illiquid Supply
Q: What exactly counts as “illiquid” Bitcoin?
A: Illiquid Bitcoin includes coins that haven’t moved in over 155 days (long-term holder threshold), those stored in cold storage, and balances held by entities with a history of non-trading behavior. These are considered economically inactive.
Q: Does a high illiquid supply guarantee price increases?
A: Not directly—but it creates favorable conditions. Reduced sell pressure combined with steady demand increases the likelihood of upward price movement, especially during periods of heightened adoption or macro uncertainty.
Q: How does the Bitcoin halving affect illiquid supply?
A: Post-halving, miners receive fewer new BTC as rewards, reducing immediate sell pressure. This often encourages accumulation behavior among both miners and investors, accelerating the shift toward illiquidity.
Q: Can illiquid supply decrease?
A: Yes—during major market events like exchange collapses, large wallet movements, or macroeconomic crises. However, recent trends show that even when large holders move coins, many redistribute to other non-exchange wallets rather than selling.
Q: Is 72% illiquidity sustainable long-term?
A: Yes, especially as Bitcoin matures. As adoption grows and more investors treat BTC as a savings vehicle, the proportion of held coins is expected to stabilize at high levels—potentially exceeding 80% in future cycles.
The Bigger Picture: Bitcoin as Digital Scarcity
The surge in illiquid supply reinforces a core thesis behind Bitcoin’s value proposition: scarcity through decentralization. Unlike fiat currencies or even gold, Bitcoin’s fixed supply of 21 million units—combined with increasing holder conviction—creates a deflationary pressure that is unique in financial history.
Moreover, as new issuance slows and institutional custody solutions improve, we’re witnessing a structural shift: Bitcoin is transitioning from a volatile newcomer to a globally recognized reserve asset.
This isn’t just speculation—it’s measurable on-chain behavior. Every dormant wallet, every unmoved coin, adds another layer of scarcity and resilience to the network.

Final Thoughts
Bitcoin’s illiquid supply surpassing 14 million BTC is not just a milestone—it’s a signal. It reflects a maturing ecosystem where holders are voting with their wallets for long-term value preservation over short-term gains.
As liquidity tightens and demand potentially grows, the stage could be set for another chapter in Bitcoin’s cyclical story—one driven not by hype, but by fundamental scarcity and unwavering holder confidence.
For investors and analysts alike, monitoring the balance between liquid and illiquid supply will remain a crucial tool for understanding market dynamics and anticipating future movements in one of the world’s most transformative assets.
