What Happens to Your Crypto When You Die? How to Make Sure Your Bitcoin Does Not Die With You

October 10, 2026 · 8 min read

Most of the things you own have someone standing behind them. A bank will eventually release a deceased customer's balance to the estate. A pension provider has a form. Even a social media account has a memorialisation process. Cryptocurrency is the exception. There is no customer service line for a hardware wallet, no reset button for a seed phrase, and no court order that can move coins out of an address when nobody alive knows the key. If you hold any crypto at all, what happens to it when you die is decided almost entirely by what you write down now.

This guide walks through the two very different situations (coins on an exchange versus coins in a wallet you control), explains why a will on its own does not solve the problem, and gives you a short plan that a non-technical spouse, child or executor could actually follow. It is written for ordinary holders, not whales, and it assumes your family currently knows roughly nothing about how this works.

Why crypto is different from every other asset you own

With a bank account, ownership and access are separate things. Your executor proves ownership with a death certificate and a grant of probate, and the bank provides access. With self-custody crypto, ownership and access are the same thing: whoever holds the private key (in practice, the 12 or 24-word seed phrase) controls the coins, and nobody else can. A judge can rule that your bitcoin belongs to your daughter, and it changes nothing on the blockchain. The coins simply sit there, visible to everyone and spendable by no one.

Nobody knows exactly how much bitcoin has already been lost this way, through death, forgotten passwords and discarded hard drives, but a widely cited 2017 Chainalysis estimate put the figure somewhere between 2.8 and 3.8 million coins, a meaningful share of everything that will ever exist. Every one of those coins had an owner once. The point of this guide is to make sure yours are not added to the pile.

Situation one: your crypto is on an exchange

If you buy and hold on a platform such as Coinbase, Kraken, Binance or a broker app, you do not hold the keys; the exchange does. In that case your crypto behaves much more like a brokerage account. The company has your identity on file, it has an account that can be frozen and transferred, and most large exchanges have a formal process for a deceased customer's account. Typically the executor or next of kin contacts support, provides a death certificate, proof of their own identity, and proof of authority over the estate (probate, letters of administration, or the local equivalent), and the exchange either transfers the assets to an account in the heir's name or sells them and pays out the cash value.

That sounds reassuring, and compared with self-custody it is. But it still fails in a predictable way: your family has to know the account exists. Exchanges do not go looking for heirs, and a login that nobody knows about, tied to an email nobody can open, is for practical purposes lost. The same applies to the two-factor authentication app on your phone. If your phone is wiped or locked, the recovery process gets slower and harder, though usually not impossible, because the exchange can verify identity through its own documents.

• Write down every exchange and app where you hold crypto, the email address each account uses, and roughly what is held there. Not the password; the existence.
• Make sure someone can get into that email account after you die. Our guide to Google's Inactive Account Manager covers Gmail; most providers have something similar.
• Keep your identity documents in a place your executor knows about. Exchange bereavement processes are document-heavy.
• Check whether the exchange offers a beneficiary or 'trusted contact' feature. Some do; most still do not, so do not assume.

Situation two: self-custody (hardware wallets, mobile wallets, cold storage)

If you moved your coins to a Ledger, a Trezor, a phone wallet, or a paper backup, you are your own bank, and when you die the bank closes. The device itself is not the asset; the seed phrase is. Anyone with the 12 or 24 words can recreate the wallet on any compatible app and spend everything, and anyone without them cannot, no matter what the will says. This cuts both ways: a seed phrase is also the single most dangerous thing to leave lying in a drawer, because a cleaner, a burglar or a relative with a grudge can empty it without leaving a trace.

So the problem to solve is not 'how do I tell my family the words' but 'how do I make sure the right person gets the words, at the right time, and nobody else gets them before that'. There are four common approaches, from simplest to most robust.

1. The sealed envelope

Write the seed phrase on paper (never a photo, never a note on your phone, never an email draft), seal it, and put it somewhere safe that your executor knows about: a home safe, a solicitor's strongroom, a bank safe deposit box. Store a second copy in a different place in case of fire or flood. The weakness is obvious: whoever can open the envelope can spend the coins today, so this only works with people you trust absolutely and a location they cannot casually reach. It is still far better than nothing.

2. Split the secret

Give half the words to one person and half to another, or use a proper scheme such as Shamir's Secret Sharing (supported by some hardware wallets) that splits the secret into, say, five pieces of which any three can rebuild it. Nobody can act alone, and losing one piece is survivable. The cost is complexity: the people holding the pieces need to know what they are holding and how to combine them, and that has to be written down somewhere too.

3. Multisig and inheritance services

A multi-signature wallet requires more than one key to spend, for example two of three keys held by you, your spouse and a lawyer or a specialist custody company. Some companies now sell this as an inheritance product: you keep control while alive, and a pre-agreed combination of heirs and the company can recover the funds after your death with the right documents. This is the most robust option and also the most expensive and the most dependent on the company still existing in twenty years.

4. A dead man's switch for the instructions, not the keys

This is the approach we think fits most ordinary holders. You do not put the seed phrase itself in any online service. Instead you write a plain-language letter that explains what you hold, where the exchange accounts are, where the sealed envelope is, who holds the other half, and what to do first, and you arrange for that letter to be delivered to a named person only if you stop checking in. A service like FinalSaying does exactly this: you check in periodically, and if you stop, your messages go to the people you chose. The letter unlocks the plan; the plan unlocks the coins. If you want the mechanics, our dead man's switch email setup guide covers them, and the security and privacy post explains why the secret itself should still live offline.

Why your will is necessary but not sufficient

You should absolutely mention your crypto in your will, or in a letter of wishes alongside it, because that is what gives your executor the legal authority to deal with exchanges and settles who is entitled to what. But a will becomes a public document in many jurisdictions once probate is granted, so it must never contain a seed phrase, a password or a private key. The will says 'my digital assets go to X and the access instructions are held by Y'; the instructions live elsewhere. If you have not thought about this before, our post on whether your will covers your online accounts is the natural companion to this one.

Also tell your executor, in writing, that crypto exists and may be taxable. In most countries inherited crypto is valued at the date of death for inheritance tax, and selling it later can trigger capital gains tax on any rise since then. The rules vary a lot by country, change often, and are well beyond this article, so the instruction to your executor is simply: ask an accountant before selling.

The one-page plan your family could actually follow

Here is what a complete, realistic setup looks like for someone with a modest holding across one exchange and one hardware wallet. It takes an afternoon.

1. Make an inventory: every exchange, every wallet app, every hardware device, the email tied to each, and a rough value. Date it. Update it when something changes.
2. Write the seed phrase of each self-custody wallet on paper, twice. Seal both copies. Put them in two secure places. Never type the words into anything connected to the internet.
3. Decide who inherits and who executes. They can be the same person, but the executor must be someone who will patiently work through documents.
4. Write a plain-English instructions letter: what you hold, where the envelopes are, which exchange to contact, which email to recover, the name of a crypto-literate friend or adviser they can call, and the order to do things in (secure the seed phrase first, sell nothing in a panic).
5. Put the existence of the assets, and the name of the person holding the instructions, into your will or letter of wishes. Keep the secrets out of it.
6. Set up delivery of the instructions letter through a dead man's switch, so it arrives without anyone needing to remember it exists, and keep the envelope offline as the actual key.
7. Test the plan once: walk the person through recovering a tiny amount into a fresh wallet from the paper backup. Twenty minutes now avoids a catastrophe later.

Mistakes we see most often

• Storing the seed phrase in a password manager, a cloud note or a photo. These are exactly the places that get compromised, and they turn a paper secret into an online one.
• Telling nobody because 'it is only a small amount'. Small amounts in 2026 have a habit of not being small later, and the recovery effort is the same either way.
• Leaving the instructions so technical that the family gives up. Write for the least technical person who might read it, and name a human they can phone.
• Relying on memory, including yours. A memorised passphrase on top of the seed (the so-called 25th word) dies with you unless it is written down too.
• Never updating the inventory. A plan that lists a wallet you emptied two years ago and misses the one you opened last month is worse than useless, because it looks complete.

Crypto was designed so that nobody can take it from you. That design does not know the difference between a thief and your grieving family. Bridging that gap is not a technical job; it is a writing job, and the sooner it is written, the more of what you built actually reaches the people you built it for.
