What Happens to Your Crypto When You Die? (And How to Make Sure Your Family Gets It)
Roughly 3.7 million Bitcoin is permanently lost — much of it from people who died without leaving access instructions. Here's how to make sure your family can actually inherit your crypto.
Picture someone who spent years building a Bitcoin and Ethereum position. They have a will and a financial advisor, but no written record of which exchanges they use, where their hardware wallet is, or what the seed phrase is. If they die or become incapacitated, their family may know crypto exists and still have no way to reach it. (This is an illustration, not a real case.)
Crypto is unlike any other asset you own. Banks have claims processes. Real estate has deeds. Crypto in self-custody has private keys and seed phrases, and if your family doesn't have them, the funds can be permanently out of reach. Ledger, a hardware wallet maker, notes that Chainalysis-based estimates put permanently lost Bitcoin at between 2.3 million and 3.7 million coins. These figures are estimates, they cover coins lost for any reason (forgotten keys, discarded drives, owners who died), and nobody can say how much of the total comes from deaths specifically.
This guide explains exactly what happens to crypto when you die, why the standard approach to estate planning completely misses the mark, and what you can do right now to protect what you've built.
Why Crypto Inheritance Is Unlike Any Other Asset
When you die, most assets go through a predictable legal process. Your bank accounts, brokerage holdings, and real estate can be transferred to heirs through probate or beneficiary designations. A lawyer, executor, or bank officer can assist. Records exist. Institutions cooperate.
Crypto doesn't work that way.
Cryptocurrency is designed to be decentralized and permissionless. There is no central authority that can "unlock" your Bitcoin for your grieving spouse or children. No phone call to customer service, no court order, no probate proceeding will help — unless your family already has the keys.
Here's what your family actually needs to access your crypto after you're gone:
- Exchange accounts — Username, password, and two-factor authentication access for each platform (Coinbase, Kraken, Binance, etc.)
- Self-custody wallet access — The seed phrase (12 or 24 words) for any hardware wallet (Ledger, Trezor) or software wallet (MetaMask, Exodus)
- Wallet addresses — So they know where to look and what to look for
- PINs and device access — For hardware wallets especially, the PIN or passphrase matters
Without this information, recovery is generally impossible. Ledger's own guidance says that bitcoin can only be recovered if the lost keys or seed phrase are found again, or in rare cases through specialist recovery services that depend on partial information the owner still has.
What Most People Get Wrong About Crypto Estate Planning
Mistake #1: Assuming Your Will Covers It
A standard will can name your spouse or children as beneficiaries of your "digital assets." But a will does not transfer the ability to access those assets. It's the legal right without the practical means.
Your executor can wave a court order at a Bitcoin blockchain all day long. It won't respond.
Mistake #2: Telling One Person and Calling It Done
Some crypto holders tell their spouse "I have Bitcoin on Coinbase." That's not a plan — that's a hint.
Mistake #3: Writing Down the Seed Phrase and Leaving It Somewhere Obvious
The opposite mistake: writing your 24-word seed phrase on a sticky note in your desk drawer. This solves one problem by creating another — anyone who finds it can drain your wallet in minutes.
Mistake #4: Keeping It All in Your Head
Some long-term holders never write anything down. That can be a security strategy, but it is not an estate planning strategy, and it fails the moment you are incapacitated.
Mistake #5: Not Documenting the Full Picture
You might have crypto on three exchanges, two hardware wallets, and a hot wallet on your phone. Your family needs to know about all of it.
The Real Risk: Lost Crypto Is Gone Forever
Most traditional assets, such as life insurance, sit with an institution that has a claims process for heirs. Crypto held in self-custody has no institution behind it. Nobody can reset a seed phrase for you, and the blockchain does not respond to a court order.
Crypto held on an exchange is easier, but not automatic. Coinbase, for example, says it does not currently support naming a beneficiary on an individual account. Ownership passes under estate planning documents or state intestacy law, and Coinbase asks for a death certificate, probate documents, the executor's photo ID and a signed letter of instructions.
A Practical Checklist for Crypto Inheritance Planning
Step 1: Create a Complete Asset Inventory
Write down every place you hold crypto — exchange accounts, hardware wallets, software wallets, staking platforms, NFT collections.
Step 2: Decide on an Access Strategy
- Sealed letter to your attorney — simple but can go out of date
- Safety deposit box — physically secure but requires family to know it exists
- Shamir's Secret Sharing or multi-sig — highest security, most complex
- A dedicated digital vault — balances security with practical usability for non-technical family members
Step 3: Write Clear Instructions, Not Just Passwords
Your family may not know what a seed phrase is. Write step-by-step instructions as if explaining to someone who has never heard of crypto.
Step 4: Tell Someone the Plan Exists
You don't have to hand your spouse all your passwords today. But someone you trust needs to know: "I have a plan. Here is where to find it."
Step 5: Review and Update Regularly
Set a calendar reminder — annually, at minimum — to review your plan and update it.

Frequently Asked Questions
Can my family inherit crypto without my private key or seed phrase?
In almost all cases, no. If your crypto is held in self-custody, the seed phrase is the only way to access it. Without it, the funds are permanently inaccessible.
Does crypto get included in my estate for probate purposes?
Coinbase's own help page says that ownership of an account passes under estate planning documents or state intestacy law, and that it requires probate documents before it will help an executor. Rules differ by state and by platform, so talk to an estate attorney about your situation. Legal authority also does not equal technical access, which is why your documentation plan matters as much as the legal one.
Is it safe to write down my seed phrase?
Writing a seed phrase down creates a physical security risk, and keeping it only in your head creates an access risk. Either way, anyone holding the phrase controls the funds. The point is to choose a storage method deliberately, rather than by default.
What if I use an exchange like Coinbase?
Exchange-held crypto is usually easier to handle than self-custody. Coinbase, for example, has an Executor Services process that asks for a death certificate, probate documents (such as Letters Testamentary or a Small Estate Affidavit), photo ID of the person named in those documents, and a signed letter of instructions. Other exchanges have their own rules. Your family must first know the account exists.
How often should I update my crypto inheritance plan?
At minimum, review your plan once a year and after any major change: new exchange account, new wallet, new device, password change.
