An early Bitcoin owner who purchased a Casascius gold bar containing a private key finally redeemed the 100 BTC after holding it for 13 years. The decision to move the coins came as the value of the gold bar became too high to risk keeping in one place.
The Story Behind the Redeemed BTC
The owner acquired the gold bar in 2012 for just $500, unaware of its future worth. After unsealing the bar and exposing the private key on the Bitcointalk forum, the BTC was transferred to multiple new wallets for security. However, this action led to unintended consequences—the loss of all forked coins (including Bitcoin Cash and BSV) when a third party swept them from the compromised wallet.
Key Details:
- Original Purchase Price: $500 (2012)
- BTC Value at Redemption: Over $10.6M (100 BTC)
- Storage Duration: 13 years
- Forked Coins Lost: BCH, BSV, and other altcoin forks

Why Casascius Gold Bars Are Unique
Casascius gold bars were early physical Bitcoin storage solutions, embedding private keys within tamper-proof holograms. Only 35 unopened 100-BTC bars remain today, collectively holding over $3.9B in value.
Security Risks of Physical BTC Storage:
- Theft Risk: Anyone with access to the private key can drain the funds.
- Loss of Forked Coins: Early wallets qualify for hard-forked assets, but exposing keys forfeits them.
- No Recovery Mechanism: Unlike custodial wallets, physical keys offer no recourse if compromised.
Lessons from This Case
- Never Share Private Keys Publicly – Posting keys online invites immediate theft.
- Split Large Holdings – The owner wisely distributed 100 BTC across 10 addresses.
- Claim Forked Coins First – Always secure forked assets before revealing keys.
