Five Bitcoin addresses first funded in April 2014 sent a combined 107.13 BTC, worth roughly $8.5 million, to an effectively unspendable address on May 25, 2026.
The destination was 1111111111111111111114oLvT2, an address designed without a known spendable private key. Any Bitcoin sent there is permanently removed from circulation. The five transactions were confirmed in the same block, used the same fee rate, and shared the same locktime – strong evidence they were prepared together rather than being five unrelated mistakes.
More than three months later, independent Bitcoin researcher Bennet published an analysis showing the burn was almost certainly deliberate. The question of who did it, and why, remains completely unanswered.
A $1 Million Round Trip Before the Burn
The most unusual detail involves one of the five wallets. It received 20 BTC on April 10, 2014, when Bitcoin traded near $364, and then sat completely untouched for nearly 12 years.
On March 18, 2026, the entire balance moved to a P2SH address that Bennet identified as behaving like a customer deposit address belonging to a multisignature custodian. Deposits entering that address were rapidly swept into larger consolidation transactions, a pattern typical of exchange or custodial infrastructure.
Then the Bitcoin came back. Between April 6 and April 8, the original wallet received three payments of 7 BTC, 7 BTC, and just over 6 BTC, restoring almost its entire former balance. In total, 20.00010537 BTC went out and 20.00006037 BTC came back. The difference was only 4,500 satoshis.
Seven weeks later, that restored balance was sent to the burn address along with the other four wallets. Whatever happened while the BTC sat inside the apparent custodian cannot be determined from public blockchain records, but the near-identical amount returning to the original address makes this look very different from an ordinary sale.
One Holder, Five Wallets
Bennet identified several links between the five addresses that point to a single early Bitcoin holder. All five were initially funded on April 10, 2014, within roughly 25 Bitcoin blocks of one another. One of the smaller addresses had also been transferring BTC to the same apparent custodial destination since 2022, sending about 19.6 BTC across roughly 60 separate payments before the final burn.
The shared funding date and custodial patterns strongly suggest these wallets belonged to the same person or entity. The coordinated burn on May 25, with matching transaction parameters across all five wallets, reinforces that conclusion.
The total amount destroyed – 107.13 BTC – was worth between $8.3 million and $8.5 million at the time of the transfer. At current prices near $77,000, that Bitcoin would be worth approximately $8.25 million today. The burn removes these coins from the effective circulating supply permanently.
A Growing Pattern of Dormant Wallet Activity
The burn is part of a broader wave of activity from early Bitcoin holders that has picked up in 2026. Earlier this month, another whale moved about $383 million in BTC after 8.5 years of dormancy, according to the Bitcoin Foundation. A separate wallet holding 445 BTC, dormant for nearly 13 years, recently sent its funds to Kraken. And a 480 BTC wallet from 2012 reactivated in early September, moving coins to a new address.
Galaxy Research has described this phenomenon as the great redistribution of old Bitcoin, arguing that the process is largely complete. Early miners and holders who acquired BTC when it was worth pennies or a few dollars have been gradually moving or selling their positions as prices reached levels that represent life-changing wealth.
But burning is different from selling. A sale puts coins back into circulation for someone else to hold. A burn removes them forever, reducing the total supply of an asset with a hard cap of 21 million coins.
Why Burn Bitcoin?
Sending Bitcoin to an unspendable address is irreversible. There is no undo button, no recovery mechanism, and no way to prove who controlled the private keys before the burn happened.
The practice is rare but not unprecedented. Bitcoin users have burned coins for various reasons over the years, including as tribute, to increase scarcity for remaining holders, or simply as a way to permanently dispose of assets they no longer want accessible. In some cases, burns have been linked to legal disputes or estate settlements where the owner preferred destruction over the risk of the coins being claimed by others.
The $1 million round trip to a custodian adds a layer of complexity that makes this case particularly unusual. If the Bitcoin was held on an exchange or custody platform, the owner may have needed to withdraw it before burning. The custodian behavior – rapid sweeping of deposits into consolidation transactions – is consistent with how major platforms handle customer funds.
Some researchers have speculated the round trip could be related to Know Your Customer or anti-money laundering compliance checks, where the custodian verified the source of funds before returning them. Others suggest the owner may have been moving coins through a mixing service or privacy tool before the final burn, though the near-identical amounts returning to the original address argue against that theory.
The deliberate nature of the burn, the coordinated timing across five wallets, and the mysterious custodian round trip make this one of the more puzzling on-chain stories of 2026. Researchers continue to trace the wallets and analyze the transaction patterns, but so far, the identity behind the burn remains unknown.
