A Casascius physical Bitcoin minted between 2011 and 2013 had its private key stripped, and the 25 BTC (~$1.78M) transferred on-chain, Galaxy Research reports. The series, designed by Mike Caldwell, contained real private keys under tamper-evident holograms, and was discontinued in 2013. Tens of thousands of BTC remain sealed in unopened Casascius coins.

Galaxy Research has monitored the recent stripping of a private key from a Casascius physical Bitcoin minted between 2011 and 2013, leading to the on-chain transfer of the embedded 25 BTC, worth approximately $1.78 million. Created by Mike Caldwell in 2011, the Casascius coin series encapsulated actual Bitcoin private keys behind a tamper-evident holographic sticker. Possessors could peel the sticker to obtain the private key and move the funds on the blockchain. The series included various denominations — from 1 BTC to as high as 1000 BTC — and became popular within the early Bitcoin community. However, in 2013, the U.S. Financial Crimes Enforcement Network (FinCEN) deemed the production of such coins as an unlicensed money transmission activity, forcing Caldwell to cease minting and refund orders. Since then, unopened Casascius coins have been treated as rare collectibles, often trading at a premium over their face value.

Data from Galaxy Research indicates that tens of thousands of BTC remain sealed within thousands of unopened Casascius coins. This recent on-chain movement, though modest in magnitude, has drawn attention from the crypto-collector world. Each opened coin reduces the already limited supply, potentially increasing the desirability of those still intact. Because these coins were originally minted at far lower Bitcoin prices, such extractions can be seen as a class of early adopters cashing out. However, the transfer of 25 BTC had no measurable impact on market dynamics and is largely regarded as a historical footnote in Bitcoin’s evolution.
