Early physical Bitcoin Casascius Coin unsealed; 25 BTC assets successfully transferred

Monitored by Galaxy Research, a physical Casascius Bitcoin coin minted between 2011 and 2013—denominated at 25 BTC (approximately $1.78 million)—had its private key extracted and the funds withdrawn on-chain. Casascius Coins are early physical collectibles of Bitcoin, each containing a genuine BTC private key sealed inside. Holders can redeem the associated assets by peeling off the tamper-evident holographic sticker. Production of this series ceased in 2013, and tens of thousands of BTC remain locked inside unopened Casascius physical coins.
