Dormant 12-Year Bitcoin Wallet Burns $1M After Mysterious Round-Trip Transfer

According to Cointelegraph, a bitcoin wallet dormant for nearly 12 years suddenly transferred its entire balance of 20.00010537 BTC (approximately $1 million) to a major centralized exchange in March, withdrew nearly the same amount three weeks later (short by just 4,500 satoshis, about $3), and then permanently burned the bitcoin in May.

Blockchain analytics firm Chainalysis confirmed that this wallet has strong "common ownership" links to four other addresses, all of which received initial funding on the same day in April 2014, with most funds traceable to the defunct Mt. Gox exchange, suggesting the holder was an early bitcoin adopter.

Analysis by bitcoin educator Bennet shows that one of the addresses sent 19.6 BTC to the custodian in 60 transactions between 2022 and 2024. Despite bitcoin's price more than quadrupling during that period, 58 of those transfers were each close to $10,400 in dollar terms, suggesting the holder may have employed a fixed-dollar-amount liquidation strategy. The $1 million "round-trip" transfer in March returned funds nearly intact, and the burn required the same private key, making conventional transaction explanations difficult to sustain.

Chainalysis admits it cannot currently explain why the holder moved long-dormant assets through a custodian, withdrew them nearly in full, and then actively burned them. Burning bitcoin is irreversible; analysts speculate this could be a public statement to intentionally reduce bitcoin's total supply, or serve purposes such as privacy, tax, or testing old wallet arrangements, but none of these hypotheses fully aligns with all on-chain evidence.
