Bitcoin Scarcity Deepens as ETF Demand Meets Record Low Exchange Supply

More than a year after U.S. spot Bitcoin (BTC) ETFs reshaped access to the asset, the market’s most important variable is increasingly not demand, but scarcity. On-chain data shows exchange balances have fallen to roughly 2.21 million BTC—a seven-year low—at a time when major asset managers continue to accumulate. The mismatch is forcing investors to confront an uncomfortable question: in today’s Bitcoin market, are you a ‘player’, or simply ‘liquidity’?

The backdrop is straightforward. Since U.S. regulators allowed spot Bitcoin ETFs, products from BlackRock ($BLK), Fidelity, and VanEck have offered institutions and wealth platforms a familiar wrapper for BTC exposure. The narrative that followed was celebratory: ‘institutional validation’ had arrived. Yet the supply side has tightened rather than loosened. With long-term holders (often defined as wallets holding for 155 days or more) sitting on large unrealized gains and showing little inclination to sell, only an estimated ~20% of total BTC supply is meaningfully liquid, according to the column’s framing and commonly cited on-chain metrics.

Several indicators align with that picture. Surveys cited in the commentary suggest that roughly 69% of respondents plan to keep holding Bitcoin even through sharp volatility. Meanwhile, the average cost basis for long-term holders is placed around $38,900—meaning that at prices in the $70,000 range, this cohort remains deep in profit, roughly 70%+ on average. If these holders do not distribute, incremental institutional demand must compete for a shrinking pool of available coins.

This is where the author argues traditional supply-and-demand explanations fall short. The market, the piece contends, is better understood through ‘game theory’—and specifically through the incentives and constraints facing three groups: early adopters (‘OG holders’), institutional buyers, and retail investors who tend to arrive later in the cycle.

In the first proposed “round,” the relationship between OG holders and institutions resembles a ‘chicken game’: two drivers head toward each other, and the first to swerve loses. OG holders—those who accumulated BTC early at very low prices—can afford to wait. In fact, the column argues that waiting is their strongest weapon: if supply stays locked, scarcity can help push prices higher. Institutions, by contrast, face a different constraint. ETF issuers and other large allocators often have to buy to meet product demand, benchmarks, or policy mandates. When the market’s sell-side is thin, the “swerve” is effectively paying up—raising the price to entice distribution from holders who otherwise have no reason to sell.

The second “round” shifts the spotlight inward, to OG holders themselves. The author frames their collective behavior as a ‘prisoner’s dilemma’: everyone benefits most if no one sells, but each individual has an incentive to take profits before others do. The column’s key claim is that Bitcoin’s ‘HODL culture’ functions as a social coordination mechanism—creating a kind of informal cooperation equilibrium without explicit collusion. In practice, the author points to a familiar on-chain pattern: short-term holders often capitulate during drawdowns while long-term cohorts accumulate or remain steady.

Those dynamics feed into what the piece labels a self-reinforcing ‘Nash equilibrium’. If OG holders’ best response is to hold and institutions’ best response is to buy, the combined outcome is persistent upward pressure over long horizons. Higher prices, in turn, can strengthen both incentives: long-term holders become even less willing to sell, while institutions—responding to inflows, portfolio models, or competitive pressure—continue to add exposure. The equilibrium can persist until an external shock changes payoff structures dramatically, the author warns, citing risks such as war, regulatory disruption, or macroeconomic stress including stagflation.

Where the column becomes most pointed is in its assessment of what institutions are “really” buying. The argument is that large financial firms may be less focused on acquiring every marginal coin and more focused on controlling ‘infrastructure’: custody, settlement rails, and the regulatory framework that governs distribution channels. In the U.S. ETF market, for example, custody arrangements concentrate operational control even if underlying BTC remains economically owned by fund shareholders. The author highlights models such as Coinbase Custody’s role in holding BTC for certain ETFs, while other issuers build internal custody capabilities. The implication is structural: individuals may hold a substantial portion of the supply, but institutions can increasingly shape how liquidity is intermediated and how price discovery is routed.

This tension—between Bitcoin’s decentralization ethos and the growing centralization of its financial “plumbing”—is presented as a defining contradiction of the post-ETF era. In the author’s telling, Wall Street is layering a new, regulated market structure atop Satoshi Nakamoto’s open system. Whether the result is “planned” or merely the natural endpoint of mainstream adoption is left unresolved, but the trajectory is clear: more institutionalization does not necessarily mean more decentralization in how the market functions.

The piece reserves its sharpest conclusion for retail. In game-theory terms, the “last mover” is often disadvantaged because information and incentives have already been priced in. When retail investors buy at elevated levels—around $70,000 in the column’s example—their capital often provides exit liquidity for earlier cohorts taking profits or for institutions rebalancing. Both groups typically have far lower cost bases and better access to information and execution. That does not mean retail cannot profit if the broader equilibrium persists, the author notes, but it reframes retail’s role: not as a dominant “player,” but as potential ‘liquidity’ that keeps the game running.

The column closes with three outcomes that could break or reshape the equilibrium. One is a defection by large long-term holders—panic selling that cascades into a broader drawdown as other cohorts follow and institutions reduce risk. Another is a future in which institutions fully dominate the market’s rails and price formation, shifting Bitcoin from a decentralized monetary experiment toward a tightly intermediated financial product. The third is continuity: long-term holders stay committed, institutional demand remains steady, and Bitcoin continues its long-term climb—an outcome many investors prefer and one that has precedent in Bitcoin’s historical cycles.

None of these scenarios is presented as inevitable. But the underlying message is that participation without understanding the incentive structure is itself a risk. In a market increasingly defined by scarcity, custody pipelines, and who is compelled to transact, the most important question may not be where Bitcoin goes next—but where each participant sits at the table.
