Ancient Bitcoin Wallets Spring Back to Life

At least four long-dormant Bitcoin wallets have recently come back to life, stirring up questions about the return of long-lost supply. The wallets, which had been inactive for over a decade, moved a combined total of 202.84 BTC (worth around $15.73 million) between August 29 and September 4.

The largest wallet, holding 146.06 BTC, had sat untouched since November 2013 and delivered a gain of about 12,902% on a cost basis near $595. A smaller wallet dormant since November 2011 followed, worth around $3.09 million and up a staggering 2,571,899% from an average cost of roughly $3.

This means that the patient holder managed to turn roughly $120 in BTC into more than $3 million by sitting on it for close to 15 years. The oldest coins carried astronomical paper gains, with the 2011-era holdings up more than 2,000% and over 500,000% from their original cost.

The recent flurry of activity extends a trend that's sped up during the summer. Galaxy Research's blockchain monitoring data shows Bitcoin's oldest cohort, coins untouched for a decade or more, stirring at a pace rarely seen in 2026.
