Six Bitcoin wallets that had been dormant since 2011, 2012, and 2014 moved a combined 553.59 BTC between Aug. 16 and Aug. 26, according to Galaxy Research. At the time of each transfer, the holdings were worth a combined $40.15 million.
Decrypt reported that it is unusual for holders from the 2011-2014 era to still control their original coins, which is why each movement tends to draw close attention from on-chain trackers.
Each of the six wallets moved within a 10-day span
The first wallet woke up on Aug. 16. It held 8.54 BTC that had remained untouched since June 13, 2011, for 15.1 years, before moving in block 962,770 at 18:42 UTC. Galaxy Research said those coins were acquired at about $14 each and were worth about $538,000 when they moved, implying a 461,981% gain. The wallet had no sender attribution.
Two days later came the largest transfer of the group. Galaxy reported 212 BTC moving out of a wallet that had been dormant since Aug. 10, 2012, or 14.0 years. Those coins were worth $13.66 million at the time, and if sold, would represent a potential return of 557,640% on an estimated $12 cost basis.
That wallet carried the label 「Noah Doe #1396 · Salomon Client Dusted」, which Decrypt said links it to a New York lawsuit seeking to claim tens of thousands of old Bitcoin addresses as abandoned property.
Hours later, another 2011 wallet moved. Galaxy flagged 10.74 BTC, worth about $692,000 at the time, leaving a wallet dormant since June 17, 2011. This wallet also had no label, leaving both sender and recipient unknown.
After a four-day gap, two more ancient wallets moved within roughly two hours of each other on Aug. 22. One transfer involved 150 BTC leaving a wallet dormant since Dec. 26, 2014. The coins were worth about $11.75 million, and the address was tagged 「Noah Doe #1680」. Galaxy put the potential gain at 23,701%.
Shortly after 3 a.m. UTC, the fifth wallet woke up. Galaxy's tracking showed 132.31 BTC worth $10.37 million moving out of three separate 2011 addresses in block 963,519. It broke the gains down by address: the wallet beginning with 1EG5DvjR moved coins worth $4.45 million for a potential gain of 629,068%; 1928FWqd moved about $404,000 for a potential gain of 625,826%; and 1EBzWeno moved about $5.51 million, the highest of the three, for a potential gain of 807,639%, based on an estimated cost of roughly $10 per coin.
The sixth and most recent wallet moved on Aug. 26. Galaxy flagged 40 BTC leaving a wallet dormant since May 28, 2012, or 14.2 years, in block 964,127 at 10:54 UTC. This transfer stood out because the destination was labeled: Boerse Stuttgart Digital, a German crypto custody bank. Galaxy said there was no sender tag. Based on an estimated $5 cost basis, the potential gain was 1,535,911%, the highest among the six wallets.
Two possible explanations were mentioned, but neither fits every case
Decrypt said there is no confirmed explanation for why these wallets moved now. Because Bitcoin is pseudonymous, there is usually no practical way to contact the owner of a large address and ask why funds were transferred.
The report pointed to two possible factors. The first is the Noah Doe case in New York Supreme Court, where a pseudonymous plaintiff wants the court to declare 39,069 dormant Bitcoin addresses abandoned property under the state's lost-property statute.
According to Decrypt, the plaintiffs sent notice by mailing thousands of wallets tiny dust transactions carrying on-chain messages. Galaxy refers to those addresses as 「Salomon-dusted」. A judge paused a default judgment in the case in early June. Since then, named addresses have been waking up regularly, and two of the six wallets in this batch carried that tag.
The second possible factor is a security response tied to a hardware wallet issue. Decrypt previously reported that around the days of the Coldcard hardware wallet exploit, about 233,000 BTC left long-term holder wallets. The article tied that activity to a firmware flaw that drained roughly $130 million starting in late July. Owners of Coldcard, Ledger, and Trezor devices moved funds to safer setups, even though most of that supply was not actually at risk.
Still, neither theory explains the other four wallets. As the report put it, sometimes a decade-old Bitcoin wallet simply moves, though the recent pace of such activity stands out.
Reactivations of old wallets have been picking up
Decrypt said the trend of old Bitcoin wallets suddenly showing activity stretches back at least two years and has accelerated over the last six months. Earlier this month, a wallet dormant since January 2014 moved 26.96 BTC after 12.5 years. Galaxy Research described that case at the time as part of a pattern that is becoming more frequent.
Of the six destination addresses in the past week, only the 40 BTC transfer to Boerse Stuttgart Digital was linked to an exchange-related entity. The other five destinations were not connected to exchanges, according to the report. Decrypt said those coins could still be sitting in cold storage, or they could be one hop away from a sale. Across all six wallets, Galaxy Research's running tally came to 553.59 BTC, worth $40.15 million at the time the coins moved.
