The rule "not your keys, not your coins" exists because people have lost hundreds of millions in Bitcoin to lost passwords, thrown-away hard drives, and forgotten wallets. These are real, documented cases — not myths. And they contain the most important lessons in all of cryptocurrency.
James Howells — 8,000 Bitcoin in a Landfill
In 2013, British IT worker James Howells accidentally threw away a laptop hard drive containing the wallet file for 8,000 Bitcoin he had mined in 2009 — when Bitcoin was worth pennies. As of April 2026, those Bitcoins are worth approximately $544 million. The hard drive is buried under thousands of tonnes of garbage at Newport, Wales municipal landfill. Howells has repeatedly approached Newport City Council to allow excavation — offering to share a portion of the recovered Bitcoin with the city. The council has refused, citing environmental regulations and the impracticality of searching through 11 years of compacted waste. The hard drive's data is likely still intact — laptop hard drives can survive landfill conditions — but finding it would require excavating the equivalent of 3,000 shipping containers of waste.
The Man Who Paid 10,000 BTC for Pizza
In May 2010, programmer Laszlo Hanyecz posted on a Bitcoin forum: "I'll pay 10,000 bitcoins for a couple of pizzas." Another user accepted the offer and ordered two Papa John's pizzas. Hanyecz paid 10,000 BTC for pizza worth about $41. At April 2026 prices, those Bitcoins would be worth approximately $683 million. May 22 is celebrated in the crypto community as "Bitcoin Pizza Day." Hanyecz has never expressed regret — he says the pizza transaction helped demonstrate Bitcoin had real-world value at a critical early time. The pizza was delicious, he reports.
Stefan Thomas — 7,002 BTC Behind a Forgotten Password
German programmer Stefan Thomas received 7,002 Bitcoin in 2011 as payment for making an explainer video about Bitcoin. He stored the private key on an IronKey encrypted USB drive — and promptly forgot the password. An IronKey allows 10 password attempts before permanently encrypting the drive forever. As of April 2026, Thomas has used 8 attempts. He has approximately $476 million worth of Bitcoin accessible if he can remember or guess the right password. He is working with specialized cryptographic experts but as of 2026, remains at 8 failed attempts with one remaining before the password is locked forever. He has kept the drive in a safe deposit box and refuses further attempts until he is certain of the password.
Quadriga CX — $190 Million Behind a Dead Man's Password
Gerald Cotten ran QuadrigaCX, Canada's largest cryptocurrency exchange. In December 2018, he died of Crohn's disease while in India — taking the private keys to QuadrigaCX cold wallets to his grave. Approximately $190 million in customer funds became inaccessible. A subsequent investigation by Ernst & Young revealed Cotten had been running the exchange as a Ponzi scheme — most of the "missing" crypto had already been spent. But some cold wallet funds were genuinely inaccessible. Multiple customers lost their life savings. Cotten's death has been the subject of conspiracy theories — but no credible evidence of faking his death has emerged.
The Critical Lesson: How to Store Crypto Safely
- ✅ Write your seed phrase on paper — not digitally. Paper in a fireproof safe.
- ✅ Make 2-3 copies stored in different locations
- ✅ Tell a trusted family member where recovery information is stored
- ✅ Test recovery: practice restoring your wallet from seed phrase on a new device
- ✅ Use a hardware wallet (Ledger, Trezor) for significant amounts
- ❌ Never store your seed phrase digitally — screenshots, cloud notes, email
- ❌ Never store your seed phrase on an exchange if it is a significant amount
