Billions of dollars’ worth of cryptocurrency have disappeared forever — not through theft, but through poor planning. When an investor dies without sharing passwords, seed phrases or access instructions, those digital assets are effectively erased from circulation.
Analysts estimate that 15–20% of all Bitcoin is lost or inaccessible, often because the owner passed away or misplaced private keys. For expats in Thailand, where crypto adoption is among the world’s highest, the lesson is simple: safeguarding your digital assets during life is not enough. You also need a clear plan for what happens after you’re gone.
Lesson 1: Privacy Without Planning – The $500 Million Ripple Case
American banker Matthew Mellon invested early in Ripple (XRP) and amassed an estimated fortune of around $500 million. He was famously cautious about security, storing his keys in cold wallets under false names across multiple banks. When he died unexpectedly in 2018, his family could not locate or access those wallets.
Every coin remains unrecoverable to this day. Mellon’s caution — intended to protect his assets — ultimately locked them away permanently.
Lesson: Security is vital, but without documented access instructions or an appointed digital executor, privacy can destroy value just as effectively as theft.
Lesson 2: Single Point of Failure – The QuadrigaCX Collapse
Canadian crypto exchange QuadrigaCX imploded after its founder, Gerald Cotten, died suddenly in 2018. Cotten alone held the passwords to the exchange’s cold wallets, which contained roughly $190 million in customer funds.
Without those credentials, no one — not even his widow or business partners — could retrieve the assets. The case became a global example of why decentralisation still requires human checks and contingency plans.
Lesson: Never rely on a single person for digital asset custody. Multi-signature wallets, shared recovery mechanisms and professional oversight are essential.
Lesson 3: Everyday Impact – The $270K Bitcoin Inheritance
In a 2025 case reported by MSN, two sisters were set to inherit around $270,000 in Bitcoin from their late father. He had left clear evidence of the investment but no password, seed phrase or access details. Experts confirmed that without recovery information, the funds were likely lost for good.
The story resonates because it showed this is not a problem only for millionaires or traders; it can affect any family.
Lesson: Even relatively modest digital holdings can vanish without proper documentation. A secure digital-asset inventory and executor instructions make all the difference.
Lesson 4: No Heirs, No Access – The Billionaire Lost at Sea
Romanian investor Mircea Popescu was one of Bitcoin’s earliest adopters, reportedly controlling 1–2% of total Bitcoin supply — billions of dollars’ worth.
When he drowned off the coast of Costa Rica in 2021, he left no known will, heirs or access information. His holdings are believed to be permanently lost, reducing global supply and underscoring the fragility of digital wealth.
Lesson: Even the most security-minded investors need an inheritance plan. Without one, digital assets simply disappear.
The Common Thread
Each story, from family inheritance to billion-dollar empires, shares a single flaw: no succession planning for digital wealth was in place. Cryptocurrency, online income and cloud assets are easily secured but almost impossible to recover without clear documentation.
Under Thai law, these assets are treated as movable property and can be inherited through the probate process, but only if they are listed and accessible. That means your executor must know what exists, where it is held and how to prove lawful access.
What Expats in Thailand Should Do
For expats in Thailand, digital inheritance adds another layer of complexity. Many hold assets in multiple countries, while heirs often live abroad. Thai probate requires local documentation and court recognition before any asset, digital or traditional, can be distributed.
A professional digital executor helps your family avoid the same pitfalls seen in these global cases. They maintain an up-to-date inventory, manage access instructions, and ensure your crypto and online wealth are correctly declared under Thai law.
Practical Steps You Can Take
- Create a digital-asset inventory listing all wallets, accounts and platforms.
- Add digital-asset authority to your Thai will, so your executor can act lawfully.
- Use secure access structures such as 2-of-3 multisig, MPC custody or encrypted vaults.
- Review and update annually, especially after market or life changes.
Protect Your Digital Legacy
Even billionaires and early crypto pioneers have lost fortunes through poor planning. You can avoid the same mistakes with the right safeguards in place.
Your digital wealth deserves the same protection as your property and savings. A professional digital executor ensures it is secure, accessible and passed on exactly as you intend.
