Congress Just Introduced a Bill to Lock Up 1 Million Bitcoin for 20 Years
The American Reserve Modernization Act would convert the US government's $25 billion Bitcoin seizure stash into a permanent sovereign reserve. Here's what the bill actually says, who's behind it, and why some economists think it's a terrible idea.
The US government already holds roughly 328,372 Bitcoin sitting in federal wallets, accumulated through years of Silk Road busts, Bitfinex seizures, and civil forfeitures. That stash is worth more than $25 billion at current prices. And until now, it had no clear long-term home.
On May 21, 2026, Rep. Nick Begich (R-AK) and Rep. Jared Golden (D-ME) introduced the American Reserve Modernization Act in the House, backed by 17 original co-sponsors from both parties. The bill proposes transforming that seizure cache into an official strategic reserve, locked for two decades, and growing it to 1 million BTC over five years through budget-neutral purchases.
Think of it as Fort Knox for the digital age. The pitch is straightforward: America holds gold as a financial backstop, so why not hold Bitcoin? The critics, however, have a few things to say about that analogy.
What the ARMA Bill Actually Proposes
ARMA isn't emerging from nowhere. It's the legislative heir to a Senate bill introduced more than a year ago and a Trump executive order that set the policy groundwork. But it's more precise, more bipartisan, and further along in the political process than its predecessors.
The bill has five core pillars. Each one is designed to answer a specific objection: What do you do with the coins? How do you store them safely? Who pays for new purchases? How does the public know you haven't lost them? And what stops the next administration from reversing everything?
20-Year Lock
All Bitcoin in the reserve must be held for a minimum of 20 years. No discretionary sales by future administrations.
1 Million BTC Target
Treasury is directed to acquire up to 200,000 BTC per year for five years, on top of existing holdings.
Budget-Neutral
No new taxpayer money. Purchases would be funded through swaps of gold certificates or other on-balance-sheet assets.
Quarterly Audits
Treasury must publish quarterly Proof of Reserve reports and undergo independent third-party audits.
Decentralized Custody
No single custodian holds full control. BTC is distributed across geographically separated domestic cold-storage facilities.
Alt-Coin Stockpile
Seized ETH and other tokens go into a separate Digital Asset Stockpile, managed under different rules.
"The American Reserve Modernization Act positions the United States to lead confidently in the digital age while protecting taxpayer interests, strengthening financial sovereignty, and reinforcing the principles of transparency and sound stewardship."
Rep. Nick Begich, Principal Sponsor, ARMA — CryptoSlate, May 21, 2026
The co-sponsors list reads like a regional cross-section of the House Republican conference, with Buddy Carter, Ben Cline, Barry Moore, Burgess Owens, Mariannette Miller-Meeks, Mike Carey, Michael Rulli, Mike Collins, Mike Lawler, Riley Moore, and Tim Moore among the 17 original signatories. The inclusion of Democrat Jared Golden as co-lead signals this isn't purely a crypto-caucus vanity project.
How America Got Here: 18 Months of Policy Groundwork
ARMA didn't appear in a vacuum. It's the third act of a policy sequence that started with executive action and Senate ambition.
In March 2025, Sen. Cynthia Lummis (R-WY) introduced S.954, the BITCOIN Act of 2025, which first proposed the 1-million-BTC purchase program and 20-year hold. That same month, the Trump administration issued an executive order directing federal agencies to consolidate their seized Bitcoin holdings and begin treating them as long-term reserve assets. Internal Treasury estimates placed government-held BTC at roughly 198,000 to 200,000 coins at that point.
Timeline at a glance: March 2025 — Lummis introduces BITCOIN Act (S.954) in the Senate. Also March 2025 — Trump signs executive order establishing Strategic Bitcoin Reserve framework. April 27, 2026 — Rep. Begich announces ARMA at Bitcoin 2026 conference. May 21, 2026 — ARMA formally introduced in the House with 17 co-sponsors.
The executive order was a start. But executive orders die with administrations. ARMA's explicit goal is to convert that policy into statute, creating a legal framework that survives White House transitions. That's the core political argument for the bill: codify the reserve before a future president can auction it off in a budget crunch.
Between the EO and ARMA's introduction, the government's BTC holdings grew to around 328,372 coins through continued forfeitures and seizures. At roughly $77,000 to $80,000 per coin, that's a stash worth over $25 billion today. No other sovereign holds anywhere close to that amount.
The Technical Architecture: How a Digital Fort Knox Would Work
The custody question is where ARMA gets genuinely interesting from an engineering perspective. The bill's language mirrors the Lummis BITCOIN Act framework, mandating that no single entity can control the reserve's private keys.
Cold Storage and Multi-Party Custody
Bitcoin in the reserve would be held in geographically distributed, hardened cold-storage facilities across the continental US. Think physical vaults, air-gapped hardware wallets, and multi-signature setups requiring sign-off from multiple independent parties before any transaction can move. It's the institutional equivalent of a nuclear launch protocol: no single operator can unilaterally move the funds.
The model is sometimes compared to institutional custody frameworks used by major Bitcoin ETF providers, but at a scale and security level an order of magnitude higher. Firms like Coinbase Custody, BitGo, and Fireblocks may compete for sub-custodian contracts if the bill passes.
Proof of Reserve and Auditing
Every quarter, Treasury would be required to publish a cryptographic Proof of Reserve, using Merkle-tree-style attestations to prove the coins exist without exposing private keys. Independent auditors would then verify those proofs annually. This is borrowed from the playbook that crypto exchanges promised but rarely delivered after the FTX collapse. ARMA would make it mandatory for the federal government.
"[ARMA] is the single most important crypto legislation that can come out of D.C. for the long-term health and security of the United States."

Budget-Neutral Acquisition
The "no taxpayer money" framing is central to ARMA's political viability. The mechanism under study is a swap of Federal Reserve gold certificates: the Treasury holds roughly $11 billion in gold-certificate assets on its books at a statutory, below-market valuation. Revaluing those certificates to market and using the difference to fund Bitcoin purchases is one approach that's been floated. The bill doesn't mandate this specifically; it directs Treasury to identify budget-neutral methods and report back to Congress.
Important caveat: ARMA does not mandate new Treasury purchases. It authorizes up to 200,000 BTC per year and requires Treasury to identify budget-neutral acquisition methods. Actual purchases depend on Treasury's implementation plans and Congressional appropriations oversight.
Who Wins, Who Loses if ARMA Passes
The bill reshuffles incentives across a wide range of institutions. Some of the effects are straightforward. Others are genuinely unpredictable.
| Stakeholder | Potential Gains | Potential Risks |
|---|---|---|
| US Treasury and Federal Reserve | Reserve diversification, long-term hedge against dollar debasement, first-mover positioning in sovereign digital assets | Balance-sheet volatility exposure; reduced flexibility to monetize BTC in fiscal emergencies |
| FBI, DOJ, IRS | Clearer rules for handling seized crypto; consolidated custodial framework reduces operational burden | Loss of discretionary auction revenue from criminal forfeitures, which currently funds certain law-enforcement operations |
| Bitcoin ETF providers (BlackRock, Fidelity, Grayscale) | Sovereign endorsement validates BTC as balance-sheet asset; likely increases retail and institutional ETF demand | If Treasury eventually sells, volume shock could tank ETF NAVs |
| Crypto custody firms | Potential sub-custodian contracts worth billions; government stamp of approval on institutional custody standards | High-profile failure risk; regulatory burden of meeting federal security requirements |
| Foreign central banks (China, Gulf states) | US action provides political cover to build their own Bitcoin reserves | Dollar-reserve dominance potentially challenged if BTC appreciates and US holds a structural advantage |
| Individual Bitcoin holders | Reduced government sell-pressure; structural demand floor from 1-million-BTC target | Politicization of the network; regulatory-capture risk if Washington starts pressuring miners or validators |
The geopolitical dimension is real but hard to model. If the US locks up roughly 5% of total Bitcoin supply for two decades, it becomes the world's largest sovereign Bitcoin holder by a wide margin. That creates negotiating leverage in any future international framework around digital asset reserves. Whether other nations see that as a threat or a template is an open question.
"When the largest balance sheet in the world starts holding BTC for 20 years, it forces every other institution to rethink its capital allocation and reserve policy."

The Strongest Objections to ARMA
Supporters have dominated the early coverage. But the critics have substantive points that deserve serious consideration.
Volatility and Balance-Sheet Risk
Bitcoin dropped more than 70% from its 2021 peak. A sovereign reserve holding 1 million BTC at, say, $80,000 per coin would have a paper value of $80 billion. A 70% correction would wipe $56 billion off the Treasury's books. Critics argue this is precisely the kind of volatility that reserve assets are supposed to protect against, not introduce.
"Treating Bitcoin as a reserve asset is a dangerous experiment for the US, increasing systemic risk and exposing the Treasury to wild volatility rather than diversifying away from it."
Nouriel Roubini, Professor, NYU Stern School of Business — Bloomberg/Reuters coverage (verify specific piece before publication)
The "Digital Fort Knox" Is Also a Target
Concentrating a massive Bitcoin holding under federal control creates an extraordinarily high-value target. A nation-state hacking operation that compromised the Treasury's custody infrastructure wouldn't just be a financial crime; it would be a national security incident. Security researchers have noted that even a decentralized multi-sig architecture has failure modes: insider threats, compromised hardware supply chains, and the long-term risk of quantum computing undermining current elliptic-curve cryptography.
Liquidity Extraction and Market Distortion
Locking up 1 million BTC for two decades removes roughly 5% of total supply from active circulation. In a market where institutional liquidity already concentrates in ETF products, that kind of permanent removal could distort derivatives pricing, widen spreads in low-volume periods, and create feedback loops in leveraged-product markets.
Regulatory Capture and Network Politicization
Perhaps the most nuanced concern comes from within the Bitcoin community itself. Some analysts worry that once the US Treasury is a major Bitcoin holder, it gains structural incentive to influence protocol governance, push for compliance-friendly forks, or pressure miners to blacklist certain addresses. Bitcoin's value proposition is predicated on its resistance to exactly that kind of institutional capture.
Legislative Fragility
Even if ARMA passes, it faces real durability risk. The bill can be amended or repealed by a future Congress. A scenario where the US builds a 1-million-BTC reserve and then liquidates it under a future administration is not hypothetical; it would likely generate a sell-side shock large enough to reshape the market for years. The 20-year lock provides discipline but not permanence.
Still speculative: Some commentary suggests ARMA's reserve could eventually be used to offset national debt if BTC appreciates. This is not in the bill text. As of its introduction, the legislation contains no provision for using Bitcoin holdings to retire Treasury obligations.
Frequently Asked Questions
What does ARMA stand for, and who introduced it?
ARMA stands for the American Reserve Modernization Act. It was introduced on May 21, 2026, by Rep. Nick Begich (R-AK) and Rep. Jared Golden (D-ME) with 17 original co-sponsors. It's a House-level bill designed to codify the US Strategic Bitcoin Reserve into statute.
How much Bitcoin does the US government currently hold?
The US government holds approximately 328,372 BTC as of May 2026, accumulated through law-enforcement seizures, civil forfeitures, and criminal penalties. At current prices around $77,000-$80,000 per coin, that's worth over $25 billion.
How much Bitcoin would the US hold if ARMA's 1-million-BTC target is reached?
One million BTC represents roughly 5% of Bitcoin's total maximum supply of 21 million coins. ARMA authorizes purchasing up to 200,000 BTC per year for five years, adding to the ~328,000 already held. This would make the US by far the largest sovereign Bitcoin holder globally.
What's the difference between ARMA and the BITCOIN Act?
The BITCOIN Act (S.954) was a Senate bill introduced by Sen. Cynthia Lummis in March 2025. ARMA is its House counterpart, introduced 14 months later with updated bipartisan co-sponsorship, clearer Treasury oversight provisions, and the same core targets: 1 million BTC and a 20-year hold.
Will ARMA use taxpayer money to buy Bitcoin?
No. ARMA explicitly requires budget-neutral acquisition methods. One approach under study is revaluing Federal Reserve gold certificates to market price and using the difference to fund purchases. The bill directs Treasury to identify and report on feasible methods before any purchases begin.
What happens to non-Bitcoin crypto seized by the government under ARMA?
ARMA creates a separate Digital Asset Stockpile for seized Ethereum and other non-Bitcoin tokens. This stockpile is managed independently from the Bitcoin reserve and operates under different rules, reflecting the bill's view that Bitcoin occupies a unique monetary role among digital assets.
Can a future administration sell the Bitcoin reserve?
ARMA imposes a 20-year mandatory hold, meaning no administration can sell the BTC for two decades. However, a future Congress could amend or repeal the law. Converting the executive order into statute makes reversal harder but not impossible; it would require new legislation, not just a new executive order.
What is "Proof of Reserve" and why does ARMA require it?
Proof of Reserve is a cryptographic technique using Merkle trees to prove that a custodian holds specific Bitcoin amounts without revealing private keys. ARMA mandates quarterly publication of these proofs plus annual independent audits, providing public transparency about the reserve's actual holdings.
What Comes Next for ARMA
ARMA now enters the standard House committee process, likely landing before the House Financial Services Committee. Senate companion legislation from Lummis has already laid groundwork, meaning there's a plausible path to coordination between chambers. But "plausible" and "likely" are very different things in Congress.
The bill's bipartisan framing gives it more runway than the original BITCOIN Act, which was largely a Republican project. The inclusion of Golden and the broader co-sponsor list suggests the sponsors have done some coalition-building legwork. Still, the political calculus shifts the moment floor votes get within striking distance: few members want to defend a "buy Bitcoin with public assets" vote in an unfavorable news cycle.
For markets, the bill's introduction alone has already done some work. Search interest in the Strategic Bitcoin Reserve is spiking, institutional desks are updating their sovereign-reserve models, and the ETF ecosystem is recalibrating its demand projections. The actual passage of ARMA is one outcome. The other is that the bill shapes the policy conversation for the next several years, regardless of whether it ever hits the President's desk.
Either way, Washington has now officially decided that Bitcoin is worth legislating around at the macro-policy level. That shift is permanent, whether ARMA passes or not.
