Eleventh Circuit Blocks Late Bid to Recover 3,443 BTC Allegedly Lost on Destroyed Hard Drive

A federal appellate panel has shut down a Florida man’s push to claw back what he now values as more than $354 million in Bitcoin, ruling that years of delay and shifting stories doomed his claim. The Eleventh Circuit affirmed a district court’s denial of Michael Prime’s motion to retrieve property under Federal Rule of Criminal Procedure 41(g), concluding that his “inexcusable delay” prejudiced the government after agents destroyed a seized hard drive he later said held the keys to 3,443 BTC.

The core tension isn’t about whether Bitcoin was on a drive—it never is—but about timing, credibility, and finality. Prime was arrested in 2019 on counterfeiting and identity-theft-related offenses and, in 2020, received a sentence exceeding five years for access-device fraud, aggravated identity theft, and illegal firearm possession. Throughout the investigation, and again before sentencing and probation, he reportedly told authorities he had little or no crypto. Agents, operating on those representations, ended their digital-asset search and later destroyed seized devices, including an orange external drive.

Only after release did Prime reverse course, claiming the drive contained the cryptographic keys to thousands of coins. He moved in 2024 for return of property under Rule 41(g). The district court rejected the request, finding the devices were “properly destroyed” and that his long silence and contradictions barred relief. The Eleventh Circuit agreed, invoking laches—a doctrine that penalizes undue delay when it harms the other side—and added that awarding value would be inequitable even assuming the Bitcoin existed.

This decision matters because digital assets invert traditional evidence. Bitcoin lives on a public blockchain; drives merely hold private keys or wallet files that confer control. Destroy the key material and you don’t erase the coins—you lose the ability to prove ownership and spend them. That asymmetry makes timing and consistency decisive. When claimants deny holdings, they incentivize investigators to stop hunting; when they later allege vast wealth on destroyed media, they collide with laches.

The broader context: lost supply is real and, at scale, unremarkable in Bitcoin’s design. In 2010, Satoshi Nakamoto noted that coins lost to inaccessible keys marginally benefit remaining holders by tightening effective supply. A 2025 analysis from River Financial estimates: - 2.3 million to 4 million BTC—roughly 11% to 18% of total—are likely unrecoverable. - About 3.8 million BTC sit in wallets inactive for more than a decade. - With around 19.8 million of the 21 million cap already mined, the effective circulating float is likely between 15.8 million and 17.5 million BTC.

My read: courts are signaling that digital-asset property claims demand early, consistent disclosure. In practice, defendants often minimize exposure during prosecution and only later present expansive asset narratives. That psychological pivot may be understandable, but it’s legally fragile. Once the government disposes of hardware based on your own statements, you’ve erected your own laches problem.

For practitioners on both sides, there are process lessons. Defendants who genuinely hold keys on seized media should document and assert those interests promptly, even if the exact amounts are uncertain. Agencies should refine evidence-retention policies for crypto-era seizures—e.g., catalog and escrow storage devices for a defined window post-sentencing—yet the burden won’t shift fully; the claimant still owns the clock. Ethically, it’s uncomfortable when state destruction intersects with potential property, but the law will continue to favor timeliness and internal consistency over late-stage revelation.

Expect more laches-driven outcomes as courts confront seed phrases, multisig setups, and claims tied to long-destroyed devices. In a bearer-asset world, custodial discipline and credible, timely assertions aren’t nice-to-haves—they’re the entire case.
