Galaxy Research said a 2013 Casascius 1 BTC redemption triggered two valid alerts in the same Bitcoin block after funds returned to the same legacy address and were spent again.
A Casascius physical bitcoin containing 25 BTC was redeemed after 12 years, worth ~$1.78M. The series, minted by Mike Caldwell from 2011-2013, still has thousands of unredeemed coins.
Physical bitcoin refers to real-world items that store or represent BTC through printed keys or QR codes. First introduced by Mike Caldwell in 2011, it later expanded into collectible coins, paper wallets, and other formats.
A user known as 'John Galt' redeemed a Casascius bar containing 100 BTC, purchased in 2012 for <$100. Now worth >$10M. Over 17,000 unredeemed Casascius coins remain.
In 2025, more than 1,000 long-dormant Bitcoin wallets woke up, moving 123,852.58 BTC (worth over $11 billion). A single early adopter's July transfer of 80,000 BTC via Galaxy Digital accounted for nearly two-thirds of the annual dormant-address spending.
Satori Coins, physical bitcoin collectibles first issued in 2016, are back after a decade-long hiatus. The premium 'Gi' model launches Sept 25, 2025, featuring Japanese craftsmanship, 2-of-2 multisig security, and a max mintage of 3,000. Charity auctions of serial #0001-#0010 began Sept 9 on Scarce.city.
Long-dormant Bitcoin wallets became active again while BTC stayed below six figures. Onchain data shows 2,205 BTC consolidated into 22 addresses, while nearly 499 BTC from older wallets moved over three days, with some transfers linked to Kraken.
As bitcoin surged to record highs in late 2020, Casascius physical bitcoin redemptions also accelerated. About 92 coins were peeled in November, marking the highest monthly total in three years, with 20,686 still active.
