The Remarkable Rescue of a Crypto Relic
A rare 10-bitcoin Casascius gold bar worth over $1 million has been recovered after being compromised for 13 years, marking one of the most notable physical cryptocurrency rescue cases of the past decade. Originally purchased in 2012 for approximately $500, this physical Bitcoin artifact represents both historical significance and substantial modern value.
Key Details of the Incident:
- Original Purchase: Acquired in 2012 during Bitcoin's early days
- Current Value: Over $1 million at today's prices
- Critical Mistake: Exposure of private keys led to partial asset loss
- Historical Rarity: Only 35 intact 100-bitcoin Casascius bars remain worldwide
The Critical Security Oversight
After obtaining the private key hidden beneath the bar's hologram, the owner chose to distribute the Bitcoin across multiple addresses rather than liquidate - a strategy intended to safeguard the funds. While the 100 BTC were successfully transferred, disaster struck when sensitive information leaked on Bitcointalk forums.

The holder shared the mini-seed used to access funds, unaware this same key could access Bitcoin fork currencies like Bitcoin Cash (BCH). Within minutes, approximately 100 BCH (worth over $500,000) were transferred to another address.

A user named Nexusrushrush claimed responsibility for the BCH withdrawal and returned the funds to the original address. However, the compromised wallet remains vulnerable to further attacks, with no additional compensation reported since the incident.
