100 BTC Casascius Bar Redeem: A Millionaire's Tale
100 BTC Casascius Bar Redeem: A Millionaire's Tale
A Bitcoin investor, known as "JohnGalt" on Bitcointalk, recently redeemed a physical Casascius bar containing 100 BTC, purchased in 2012 for $500 when Bitcoin traded at $5. This resulted in a multi-million dollar payout.
The Risks of Physical Bitcoin Storage
Holding physical Bitcoin presents significant risks. Recent increases in crypto kidnappings highlight the dangers of physically storing large sums of cryptocurrency. JohnGalt's story underscores these risks, even for experienced investors.
On May 13, 2025, after years of deliberation, JohnGalt decided to redeem his physical Bitcoin. He unveiled the private key embedded in the Casascius bar and transferred the 100 BTC (worth over $10 million) to new addresses. The transaction was confirmed on-chain.
He explained his reluctance to redeem earlier due to the immense pressure and risks associated with storing such a valuable asset. He attempted to sell the bar multiple times but faced valuation disputes and trust issues.
“I didn’t want to redeem it; a physical, unredeemed Bitcoin feels like it’s worth more than just the money,” he wrote.
The Redemption Process and a Costly Mistake
JohnGalt documented the technical challenges of redeeming the physical Bitcoin. Initially using Electrum on Android, he encountered compatibility issues. He eventually used bitaddress.org to convert the mini-key and transferred the BTC to secure addresses via Trezor Suite.
However, he made a critical mistake. After posting a photo of the Casascius key online, before claiming his Bitcoin Cash (BCH), someone else swept his BCH holdings within nine minutes, resulting in a loss estimated at over $40,000.
Lessons Learned
- Security Risks: Physical Bitcoin storage, despite its romantic appeal, exposes users to theft, damage, and loss.
- Redemption Complexity: The process of redeeming physical Bitcoin can be technically challenging and error-prone.
- Fork Awareness: Always claim all associated cryptocurrencies from a private key before sharing it publicly.
While JohnGalt ultimately realized significant profit, his story serves as a cautionary tale highlighting the risks associated with physical cryptocurrency storage. This incident should encourage users to prioritize secure, digital storage solutions.
