A federal appeals court has rejected a Florida man’s claim seeking the return of what he said was more than $354 million in lost Bitcoin, ruling that he waited too long to take legal action and that his own inconsistent statements undermined the case. The decision, issued by the Eleventh Circuit Court of Appeals, effectively ends Michael Prime’s years-long effort to recover a hard drive he said contained the cryptographic keys to his digital fortune.
The case underscores the legal complexities surrounding cryptocurrency ownership, digital evidence, and the irreversible nature of blockchain-based assets.
A Claim Too Late to Be Heard
The appeals court upheld a lower court’s decision that denied Prime’s motion to recover the allegedly lost property, finding that he had “inexcusably delayed” his claim and prejudiced the government in the process.
“For years, Prime denied that he had much Bitcoin at all,” the judges wrote. “It was only later that he claimed to be a Bitcoin tycoon.”
Prime, who was sentenced in 2020 to more than five years in prison for access-device fraud, aggravated identity theft, and illegal firearm possession, filed the motion under Rule 41(g) — a federal rule that allows defendants to seek the return of property after their cases conclude.
However, the court found that by the time Prime acted in 2024, the hard drive at the center of the case had already been destroyed. Federal investigators had disposed of it years earlier after finding no digital assets during their initial examination.
Contradictory Statements Undermined His Case
According to court records, Prime initially told investigators, probation officers, and even his sentencing judge that he owned little or no cryptocurrency. It was only after his release that he claimed to hold 3,443 Bitcoin, an amount worth roughly $354 million at current market prices.
Relying on his early statements, federal agents had no reason to believe the seized devices contained anything of significant value. When the search turned up nothing, the items — including the orange hard drive — were destroyed according to standard evidence protocols.
By the time Prime asserted ownership of the Bitcoin, years had passed, and the physical evidence was gone. The court concluded that his delay made it impossible to verify or return the alleged property.
Legal Doctrine: The Role of ‘Laches’
The judges cited the doctrine of laches, a legal principle that bars claims brought after an unreasonable delay that disadvantages the opposing party.
Prime’s “inexcusable delay,” they ruled, left the government unable to return property that no longer existed. Even if the Bitcoin had once been on the drive, the court said, compensation would be inequitable under these circumstances.
The ruling highlights the limits of post-conviction property recovery in cases involving digital assets — particularly when evidence has been lawfully destroyed and ownership cannot be independently verified.
The Nature of Lost Bitcoin
Bitcoin is not stored on a hard drive or device in the traditional sense. Rather, ownership is controlled by private cryptographic keys — digital codes that grant access to coins recorded on the blockchain. Losing these keys is effectively equivalent to losing the Bitcoin itself, as there is no central authority or password recovery mechanism.
Without the keys, the Bitcoin remains on the blockchain but becomes unspendable and permanently inaccessible. This characteristic, while reinforcing Bitcoin’s security, also means lost coins can never be recovered or reassigned.
“Lost coins only make everyone else’s coins worth slightly more. Think of it as a donation to everyone,” wrote Bitcoin creator Satoshi Nakamoto in a 2010 forum post.
A 2025 study by River Financial estimated that between 2.3 million and 4 million Bitcoin — or roughly 11% to 18% of the total supply — are permanently lost. That figure represents as much as $400 billion at current prices, making digital loss a significant aspect of Bitcoin’s long-term scarcity.
A Familiar Story in the Crypto World
Prime’s story recalls several other high-profile incidents involving lost Bitcoin, most famously that of James Howells, a Welsh IT engineer who accidentally discarded a hard drive containing 8,000 BTC in 2013.
Howells’ lost Bitcoin, now worth hundreds of millions of dollars, became the subject of documentaries and film projects. His ongoing efforts to excavate a local landfill in search of the drive have drawn global attention — underscoring the fragile nature of digital asset storage.
Like Howells, Prime’s case reflects a central paradox of cryptocurrency: while blockchain technology ensures security and decentralization, it also places complete responsibility for asset custody on the individual owner. Once lost, recovery is virtually impossible without the private keys.
Broader Legal and Technological Implications
Legal experts note that cases like Prime’s reveal the gap between traditional property law and the realities of digital asset ownership.
While physical property can be tracked, seized, and returned, Bitcoin and other cryptocurrencies lack tangible form, existing purely as entries on a distributed ledger. Courts are still developing frameworks to handle disputes involving such assets, particularly when evidence is missing or destroyed.
In this instance, the appeals court’s decision sets a precedent reinforcing that timeliness and consistency of claims are critical in any cryptocurrency-related litigation. Delayed filings, especially when tied to contradictory testimony, are unlikely to succeed — even when the potential value is immense.
The Final Verdict
The Eleventh Circuit’s ruling closes the door on Michael Prime’s bid to recover his supposed 3,443 Bitcoin. Despite his claims of having lost a digital fortune, the court found no credible evidence to support them and emphasized that his delay had made any form of restitution impossible.
The judgment also serves as a reminder to cryptocurrency holders: secure storage and accurate disclosure are vital. In the world of decentralized finance, ownership means responsibility — and once digital keys are gone, no court can bring them back.
