Six Decade-Dormant Bitcoin Wallets Moved 553 BTC, Mostly Off-Exchange

Six bitcoin wallets that had sat untouched since 2011, 2012 and 2014 spent 553.59 BTC between 16 and 26 August, worth about $40.15 million at the prices quoted. Galaxy Research tracked all six, and every outlet running the story on Friday works from that one dataset. Five of them sent coins to addresses carrying no exchange label. The sixth sent 40 BTC to Boerse Stuttgart Digital, a German custody provider. The same research desk says dormant bitcoin is moving less this year than at any point since the third quarter of 2022.

Ten days, reported as a week

The tally is not in dispute. The window is. Decrypt's headline says one week while its own table covers ten days, 16 to 26 August; CoinDesk calls it "this month"; Coininsider says ten days. Every version carries the same six dates, so the disagreement sits in the framing and not in the data. A reader comparing two headlines gets two different pictures. The transfers themselves are modest next to the headline figure. A wallet last used in June 2011 spent 8.54 BTC on 16 August, about $538,000. Two days later 212 BTC worth $13.66 million left a wallet dormant since August 2012, and 10.74 BTC left another untouched since June 2011. On 22 August a 2014 wallet moved 150 BTC and three separate 2011 addresses moved a combined 132.31 BTC. The published dollar figures do not add up to $40.15 million, because the last entry is quoted in coins only.

Movement is not a sale

What the chain shows is a transfer, and the chain stops there. CoinDesk put the limit in plain terms, and it applies to all six.

"Movement does not necessarily mean selling, however. Bitcoin's public blockchain shows coins leaving one address and arriving at another, but usually cannot say whether the owner sold, changed wallets, moved to a custodian or simply reorganized their holdings," the CoinDesk report said.

Only one of the six went anywhere a sale could be executed, and a custody bank is somewhere to store coins as much as to sell them. Two of the wallets carry a "Salomon Client Dusted" tag in the tracking data. crypto.news adds a label of "Noah Doe #1396" on the 212 BTC wallet, which no other account mentions.

The four-year low underneath

The larger number runs the other way. Alex Thorn, Galaxy's head of research, told Cointelegraph that dormant coin movement has fallen to its lowest since the third quarter of 2022, with coin days destroyed, a measure that weights each coin spent by how long it had sat still, showing the same decline. He puts the earlier spikes down to early holders taking profit, as they did in 2017. The two accounts do not line up on period. Cointelegraph pins the four-year low to the second quarter of 2026, and CoinDesk states it as the current condition in the same report that counts coins moving in late August. Both figures come from Galaxy, and neither says which period the reading covers.

Why old coins move

Selling is one explanation and not the only one. CoinDesk ties part of this year's activity to security, noting that after the Coldcard firmware flaw was disclosed in late July, about 210,000 BTC left long-term-holder wallets in a single week. That causal reading is CoinDesk's own, and no wallet owner has confirmed it. Thorn has played down a different explanation, saying he has heard quantum concerns cited by institutional investors as a reason not to buy bitcoin at all; that rendering appears in one account. Bitcoin's exposure to quantum attack is a live subject among developers, and nobody holding these particular coins has said a word about why they moved.

Two of the six wallets sit inside a legal claim. A New York case filed in May seeks to have 39,069 dormant addresses declared abandoned property, holding roughly 3.7 million BTC between them, and at least two amicus briefs have been filed against it. Whether a court can declare a key-controlled address abandoned is untested. The coins keep moving while it is argued.
