Five Bitcoin wallets that hadn't moved a satoshi in 11 years suddenly transferred 107 BTC — worth about $8.3 million at the time — to a burn address this week. The transaction, executed in a coordinated burst, cost just $5.56 in fees. The burn address, already a graveyard for lost coins, now holds more than 807 BTC, or roughly $61 million, across over 146,000 transactions.
The 'accidental quantum bounty'
Blockstream CEO Adam Back called the incident an 'accidental quantum bounty.' His reasoning: the burn address's public key structure makes it a natural target for quantum computing attacks — not that anyone can recover the coins from a burn address. Back's comment framed the event as a quirky side effect of Bitcoin's design rather than a security flaw.
A dead man's switch?
The transaction included time-based parameters, which suggests a dead man's switch mechanism — a pre-programmed trigger that releases the coins if the owner stops checking in. That pattern, combined with the 11-year dormancy, points to a setup that may have been intended as an inheritance or long-term backup. But the coins didn't go to a heirs' wallet; they went to a known burn address, effectively destroying them. Whether the trigger fired by accident or on purpose remains unclear.
What the burn address holds
The destination address — 1111111111111111111114oLvT2 — already held over 700 BTC before this week's deposit. It's a black hole: coins sent there cannot be spent. The 107 BTC added this week pushed the total beyond 807 BTC. With Bitcoin trading around $77,000 at the time of the burn, below its 200-day moving average of $80,000, the timing isn't great for a holder who might have wanted to sell. But for a wallet that slept through a decade, maybe the owner never planned to sell at all.
