Bitcoin Strategic Reserves: Which Nations Are Accumulating BTC and Why

The idea of a nation holding Bitcoin as a sovereign reserve asset was considered fringe as recently as 2020. Today, at least three countries hold Bitcoin on their national balance sheets, a sitting US president has signed an executive order establishing a Strategic Bitcoin Reserve, and legislators on four continents have introduced bills to formalize government BTC accumulation. The race to acquire a finite, 21-million-unit asset has moved from conference panels to presidential desks.

This article maps every confirmed national holder, tracks the legislation pipeline, examines the strategic rationale behind sovereign accumulation, and addresses the criticisms.

Which Countries Hold Bitcoin Today

Three nations hold meaningful Bitcoin positions as of mid-2026. Their acquisition strategies, custody models, and motivations differ substantially.

United States: The Largest Sovereign Holder

On March 6, 2025, President Trump signed Executive Order 14233, establishing the Strategic Bitcoin Reserve. The order mandates that all Bitcoin seized through criminal and civil forfeiture proceedings be retained rather than auctioned. As of February 2026, the US holds approximately 198,000 BTC, making it the largest known sovereign holder.

The executive order explicitly states that Bitcoin in the reserve "shall not be sold." This represents a fundamental shift from prior policy: the US Marshals Service had historically auctioned seized Bitcoin, including the roughly 144,000 BTC confiscated from Silk Road.

Beyond the executive order, Senator Cynthia Lummis (R-WY) and Congressman Nick Begich (R-AK) introduced the BITCOIN Act of 2025 (S.954) on March 11, 2025, with cosponsors including Senators Jim Justice, Tommy Tuberville, Roger Marshall, Marsha Blackburn, and Bernie Moreno. The bill proposes purchasing 1 million BTC over five years, funded by $6 billion annually from Federal Reserve remittances, with a mandatory 20-year holding period. The legislation remains under consideration.

Executive order vs. legislation: The Strategic Bitcoin Reserve exists today through executive action, meaning it could be reversed by a future president. The BITCOIN Act, if passed, would codify accumulation into law and authorize active purchasing beyond seized assets.

El Salvador: The Pioneer

El Salvador became the first country to adopt Bitcoin as legal tender in September 2021 under President Nayib Bukele. The government began purchasing BTC through a dollar-cost averaging strategy, buying one Bitcoin daily regardless of price since late 2022. As of June 2026, El Salvador holds approximately 6,174 BTC valued at roughly $600 million.

The IMF pressured El Salvador to scale back its Bitcoin ambitions as a condition for a $1.4 billion financial assistance package agreed in December 2024. In January 2025, Bitcoin was officially removed as legal tender, though the government continues accumulating and has maintained its holdings. The Chivo wallet, launched with a $30 incentive per user, has been phased out as part of the IMF agreement.

Bhutan: Mining-Funded Accumulation

Bhutan took a different path: rather than buying Bitcoin on the open market, the kingdom mined it using hydroelectric power through its sovereign wealth fund, Druk Holding and Investments. At its peak in October 2024, Bhutan held approximately 13,000 BTC. Following the April 2024 halving, which reduced block rewards to 3.125 BTC and compressed mining margins, on-chain data suggests mining operations were scaled back significantly.

By April 2026, Bhutan's holdings had declined to roughly 3,954 BTC, though the government disputed reports of large-scale selling. In December 2025, Bhutan pledged up to 10,000 BTC toward developing the Gelephu Mindfulness City, a new special administrative region focused on digital finance and sustainability.

US State-Level Bitcoin Reserve Legislation

The federal executive order triggered a parallel movement at the state level. Multiple US states introduced Bitcoin reserve legislation in 2025 and 2026, with mixed results.

States That Passed Legislation

New Hampshire became the first state to enact a Bitcoin reserve law when HB 302 passed, authorizing the state treasurer to invest up to 5% of public funds in digital assets with a market capitalization exceeding $500 billion (a threshold only Bitcoin currently meets). Texas followed with SB 21, which included a cold storage mandate for custody. In November 2025, Texas purchased approximately $5 million in the BlackRock iShares Bitcoin Trust (IBIT) at a BTC price of around $91,336.

Arizona passed HB 2749, though with a significant limitation: it does not authorize direct cryptocurrency investment. Instead, Arizona's reserve can only hold unclaimed crypto assets, airdrops, and staking rewards. Two more ambitious Arizona bills (SB 1373 and SB 2324) were vetoed by Governor Katie Hobbs.

Countries Exploring Bitcoin Reserves

Several countries have explored or proposed Bitcoin reserve legislation without yet adopting it. These proposals signal growing interest even where implementation has stalled.

Brazil

Federal Deputy Luiz Gastão (PSD/CE) reintroduced Bill 4501/2024 on February 13, 2026, proposing that Brazil accumulate 1 million BTC over five years by allocating up to 5% of the country's foreign reserves. The bill would prohibit the sale of judicially-seized Bitcoin, offer incentives for corporate Bitcoin adoption and mining, and allow federal tax payments in Bitcoin. If enacted, Brazil would become the first G20 nation to codify cryptocurrency as a sovereign reserve asset. The bill remains under congressional consideration.

Czech Republic

The Czech National Bank studied allocating up to 5% of strategic reserves to Bitcoin by 2027. However, the CNB board formally voted against the proposal in February 2026, citing concerns that its risk management framework does not support highly volatile assets. The governor acknowledged that a 1% allocation could theoretically raise expected returns without materially increasing portfolio risk, but the institution ultimately declined.

Switzerland

A constitutional amendment proposal known as the "Bitcoin Initiative" was approved by the Federal Chancellery and is actively collecting the 100,000 signatures required to trigger a public referendum. The Swiss National Bank has publicly rejected the idea, citing Bitcoin's volatility, its relatively small market capitalization compared to traditional reserves, and its software-based nature.

Poland

Presidential candidate Sławomir Mentzen of the Confederation party pledged to create a Strategic Bitcoin Reserve during his May 2025 campaign. He finished third with approximately 14.8% of the first-round vote. The proposal has not translated into institutional policy.

Why Nations Are Accumulating Bitcoin

The motivations behind sovereign Bitcoin accumulation vary by country, but several recurring themes emerge across all proposals.

Inflation Hedge and Reserve Diversification

Bitcoin's fixed supply of 21 million units makes it structurally deflationary relative to fiat currencies. For countries holding large dollar-denominated reserves, Bitcoin offers diversification away from a single currency's monetary policy. Senator Lummis framed the BITCOIN Act as a tool to "secure America's financial future" and positioned it as a hedge against dollar debasement.

Reducing Dependence on Traditional Financial Rails

The SWIFT network has been weaponized as a geopolitical tool, most notably through the disconnection of Russian banks in 2022. Countries seeking alternatives to dollar-denominated settlement systems view Bitcoin as a censorship-resistant monetary network that no single government controls.

Signaling Innovation and Attracting Capital

El Salvador's Bitcoin adoption, despite IMF pushback, attracted significant attention from the global crypto industry. The country positioned itself as a hub for Bitcoin entrepreneurs and developers. Texas has similarly leveraged its Bitcoin-friendly legislation to attract mining operations and fintech companies.

Monetizing Stranded Energy

Bhutan's model of mining Bitcoin with surplus hydroelectric power illustrates a distinct motivation: converting stranded energy assets into a globally liquid store of value. Countries with excess renewable capacity (geothermal, hydro, solar) can use proof-of-work mining to monetize energy that would otherwise go unsold.

The Game Theory of Sovereign Accumulation

Bitcoin's fixed supply creates a pure coordination game among nation states. Once a major economy begins accumulating, other nations face a strategic dilemma: accumulate now at current prices, or risk paying significantly more later as supply tightens.

This dynamic mirrors the prisoner's dilemma. Each country individually benefits from early accumulation regardless of what others do. If others also accumulate, early movers benefit from lower acquisition costs. If others do not accumulate, early movers hold an asymmetric advantage in a potential future where Bitcoin becomes a significant reserve asset.

The domino thesis: When the United States signed Executive Order 14233, it raised the stakes for every other nation. A country that dismisses Bitcoin reserves faces the risk of falling behind if the asset appreciates, while early accumulators face only the downside of temporary volatility.

The corporate parallel strengthens this dynamic. Strategy (formerly MicroStrategy), the largest corporate Bitcoin holder, held approximately 818,334 BTC as of late April 2026 with a cost basis of roughly $61.8 billion. A single corporation holding more Bitcoin than every sovereign nation combined creates implicit pressure on governments to act.

Custody and Security Challenges

Sovereign Bitcoin holdings introduce key management challenges that differ fundamentally from managing traditional reserves like gold or Treasury bonds.

Gold reserves sit in vaults with physical security. Dollar reserves exist as ledger entries at the Federal Reserve. Bitcoin reserves require managing cryptographic keys: whoever controls the private keys controls the Bitcoin. This creates novel attack surfaces and operational requirements.

• Cold storage with air-gapped signing devices reduces hack risk but introduces operational complexity for a government bureaucracy
• Multisig custody can distribute key control across agencies but requires cross-departmental coordination
• Hardware security modules (HSMs) provide institutional-grade key protection but require specialized personnel
• Succession planning must account for political transitions without creating single points of failure

Texas's SB 21 explicitly mandates cold storage for state Bitcoin holdings, making it one of the first pieces of legislation to codify custody requirements for sovereign digital assets.

Criticisms and Risks

Sovereign Bitcoin reserves face legitimate criticism from central bankers, economists, and policymakers. These objections deserve serious consideration.

Volatility

Bitcoin's annualized volatility has historically been roughly three times that of gold. Traditional sovereign reserves prioritize stability and liquidity: central bank mandates focus on preserving purchasing power, not maximizing returns. The European Central Bank's president has stated that "Bitcoin will not enter the reserves of any of the central banks of the EU," citing incompatibility with stability mandates.

Opportunity Cost

Capital allocated to Bitcoin cannot simultaneously fund infrastructure, debt reduction, or other productive investments. Brazil's proposal to allocate 5% of foreign reserves to Bitcoin would represent tens of billions of dollars redirected from conventional instruments. Critics argue that sovereign reserves should prioritize liquidity and capital preservation over speculative appreciation.

Institutional Mismatch

An important distinction exists between central bank reserves and sovereign wealth funds. Central banks operate under tight stability mandates and short-term liquidity requirements that make volatile assets inappropriate. Sovereign wealth funds, with longer time horizons and broader mandates, may be better suited for Bitcoin exposure. Bhutan's approach through Druk Holding (a sovereign wealth fund) rather than its central bank reflects this distinction.

Political Risk

Executive orders can be reversed by successor administrations. The US Strategic Bitcoin Reserve exists by presidential action, not legislation. Unless the BITCOIN Act passes, a future president could order the liquidation of the entire reserve. This creates uncertainty for any long-term strategic rationale.

Sovereign Holdings vs. Corporate and ETF Holdings

The disparity is striking: a single US corporation holds more Bitcoin than all sovereign entities combined. If the BITCOIN Act's target of 1 million BTC were achieved, the US government would hold nearly 5% of Bitcoin's total supply.

What Sovereign Adoption Means for Bitcoin Infrastructure

When nation states treat Bitcoin as a reserve asset, the entire ecosystem benefits from a legitimacy signal that ripples outward. Regulatory clarity tends to follow government adoption: institutional investors gain confidence, banking partners become more willing to serve Bitcoin businesses, and developers build with greater certainty that the asset class will persist.

Sovereign demand also intensifies the need for robust self-custodial infrastructure. If governments are holding Bitcoin, individuals and institutions will follow, and they will need tools to hold, transfer, and transact with BTC that do not depend on centralized intermediaries. Layer 2 protocols like Spark address this by enabling instant, self-custodial Bitcoin transfers without on-chain transaction costs, making Bitcoin practical as both a reserve asset and a medium of exchange.

As more sovereign entities accumulate BTC, the distinction between "store of value" and "payment network" narrows. Nations holding Bitcoin as reserves will eventually need payment infrastructure to deploy it: settling trade obligations, distributing aid, or enabling citizen access. The Layer 2 ecosystem, from Lightning to Spark, becomes critical infrastructure for sovereign Bitcoin utility.

What to Watch Next

Several developments in the coming months will shape the trajectory of nation-state Bitcoin adoption.

• Whether the BITCOIN Act advances through the US Senate would transform the reserve from executive action into durable policy
• Brazil's congressional deliberation on Bill 4501/2024 could produce the first G20 nation to legislate Bitcoin as a sovereign reserve asset
• The Swiss Bitcoin Initiative's signature collection, if successful, would trigger the first national referendum on central bank Bitcoin holdings
• Additional US state legislation following the New Hampshire and Texas models could create a patchwork of sub-sovereign Bitcoin reserves
• Whether countries currently holding seized Bitcoin (Germany, UK, China) shift from liquidation to retention policies

For developers building on Bitcoin, sovereign adoption validates the long-term thesis. The Spark SDK and tools like General Bread make it possible to build applications on Bitcoin Layer 2 infrastructure that can scale alongside growing sovereign and institutional demand. As nations accumulate, the need for fast, low-cost, self-custodial Bitcoin infrastructure only grows.
