Blockchain analysis has uncovered new details regarding a series of wallet addresses that deliberately destroyed millions of dollars worth of Bitcoin. According to findings from Chainalysis and crypto educator Bennet, five wallets that ultimately burned their Bitcoin appear to have been controlled by a single individual who was likely an early adopter with funds linked to the collapsed Mt. Gox exchange.
The mystery centers around 107 BTC that was burned in May, valued at approximately $8.5 million at the time. Chainalysis reported strong indicators of common ownership across the five addresses, which were all initially funded on the same day in April 2014 and subsequently sent dollar-equivalent amounts of BTC to a deposit address at a large centralized custodian.
The $10,400 Clue and Planned Liquidation
Data from one of the addresses shows it sent 19.6 BTC across 60 transactions to the custodian between 2022 and 2024. While the BTC amounts varied between 0.15 BTC and 0.62 BTC, 58 of the 60 transfers were valued within 10% of roughly $10,400 at the time they were sent, despite Bitcoin's price quadrupling during that period. Bennet noted that this pattern suggests a planned liquidation strategy operating in clusters rather than on an automated schedule.
The Mysterious $1 Million Round Trip
Earlier this year, another of the wallets—dormant for nearly 12 years—suddenly moved 20.00010537 BTC to a large crypto custodian. Three weeks later, almost the exact same amount was returned to the same address, minus roughly $3. The returned funds were split into three transactions over three consecutive days, which Bennet suggested aligned with daily custodian withdrawal limits.
Less than two months after receiving the funds back, the Bitcoin was deliberately sent to an unspendable address and destroyed. Because spending the Bitcoin in March and burning it in May required the same private key, transaction history indicates the same key holder controlled the coins before and after the round trip.
Unanswered Questions
Various theories have been proposed to explain the behavior, including testing an old custody arrangement after years of dormancy, complying with tax or compliance requirements, or utilizing the custodian to obscure the funds' onchain trail for privacy. However, none of these explanations fully account for why the owner would retrieve the funds only to destroy them shortly afterward.
Because burning Bitcoin is irreversible, the owner deliberately chose to send the assets where they can never be spent again. Chainalysis and other analysts acknowledge that while the blockchain provides a detailed record of the transfers, the underlying motivation remains unknown.
