Two Casascius physical Bitcoin coins containing roughly $2,000 in BTC were moved this week after remaining dormant for 13 years, according to Sani, founder of Timechain Index. Casascius produced early physical Bitcoins that hide a usable private key under a tamper-evident hologram; revealing that key lets the holder redeem the coin’s Bitcoin on the blockchain.
These coins are among the first physical representations of Bitcoin and are treated as rare collectibles. Any on-chain activity involving them attracts attention from collectors and blockchain watchers because they connect the hobbyist era of Bitcoin’s early days with today’s market. Periodic reactivation happens when an owner decides to access or spend the stored funds, and such movements often renew interest in these historical pieces and their stories.
