Four long-dormant Bitcoin wallets moved a combined 1,971.03 BTC, roughly $161 million, over the past two weeks, according to Galaxy Research. The largest single stash—1,260.78 BTC worth about $100.63 million—had been untouched since 2016.

Per Galaxy Research's blockchain monitoring, the awakened wallets moved 1,971.03 BTC in total between Sept. 6 and Sept. 22. The largest wallet, holding 1,260.78 BTC worth approximately $100.63 million, had sat dormant since July 2016—more than 10 years—potentially delivering a gain of roughly 12,122% on a cost basis near $652.

The oldest coins carried even larger returns in percentage terms. A wallet dormant since March 2011, holding 10.25 BTC now worth about $792,000, notched a gain of more than 8.38 million percent from an average cost of around $1. Another 100 BTC, untouched since November 2011 and valued at about $8.09 million, was up roughly 2.49 million percent.

The most recent transfer stirred just hours before publication. Early Tuesday, a wallet holding 600 BTC, worth about $51.9 million, moved coins that had been dormant since July 2012—a 14.2-year slumber that could have a gain of more than 1 million percent.

Three of the four wallets carried a "Noah Doe" sender tag, a reference to a New York lawsuit that seeks to have thousands of dormant Bitcoin addresses declared abandoned property—a designation that, if successful, would put the coins under state control. Named wallets tied to that case have been stirring regularly since a judge paused the proceedings in June.

The activity extends a trend that has defined Bitcoin's on-chain activity in 2026. An earlier wave saw six wallets move roughly $40 million in a single 10-day stretch, and a Galaxy chart showed Bitcoin's oldest cohort—coins untouched for a decade or more—stirring at a pace rarely seen.

Such movements draw scrutiny because so few holders from Bitcoin's earliest days still control their private keys, making each awakening a potential signal of long-lost supply returning to circulation.

A transfer alone does not reveal whether an owner is selling, consolidating, or shifting to new custody, and the recipient of the latest 600 BTC transfer was not identified on-chain. With Noah Doe-tagged wallets stirring regularly since the June pause, the next signals to watch are further movements from addresses tied to the suit and any onward transfers of the coins now in motion.
