When someone dies, their cryptocurrency doesn’t disappear. It sits on the blockchain exactly where they left it, untouched and waiting. But without the right information, no one can move it, claim it, or even confirm what it’s worth. It may as well not exist.
This is a problem that catches families off guard. They discover a deceased parent or partner owned thousands of dollars in Bitcoin, find a reference to an account on Coinbase, and then hit a wall. No password. No backup codes. No idea where to start.
This article explains what actually happens to cryptocurrency after someone dies, why it creates problems that traditional assets don’t, and what you can do to make sure your own crypto doesn’t disappear with you.
What happens to your crypto when you die
Legally, cryptocurrency is treated as personal property. In the US, it passes to your estate and is distributed according to your will, or under your state’s intestacy laws if you die without one. The IRS classifies cryptocurrency as property for tax purposes, and most states follow the same principle for probate.
In the UK, the position is similar. Crypto forms part of your estate, and your executor has a legal duty to locate and manage it.
So far, so straightforward. The problem is that legal ownership and practical access are two completely different things.
A court can confirm that your beneficiary is entitled to your Bitcoin. It cannot hand them the password to reach it. That gap, between the right to own something and the ability to actually get to it, is what makes cryptocurrency so different from almost every other asset.
Why crypto is different from a bank account
When someone dies and leaves money in a bank account, there is a process. The executor contacts the bank, provides a death certificate, and the funds are transferred to the estate. It takes time, but the path exists. The bank is an intermediary that holds the money on behalf of the customer and has both the ability and the legal obligation to work with authorized representatives.
Cryptocurrency held in a self-custody wallet has no intermediary. No company is holding it on your behalf. The crypto belongs to whoever controls the private key, a unique code that proves ownership and authorizes transactions. If that key is lost, there is no customer service line to call and no recovery process to follow. The crypto stays on the blockchain, visible to anyone, accessible to no one.
This is by design. The decentralized structure of cryptocurrency is one of its core features. For most users in life, it’s a benefit. After death, it becomes a serious liability for anyone left behind.
What private keys and seed phrases actually are
You do not need to understand blockchain to understand this distinction, but you do need to understand two terms.
A private key is a long, unique code that gives its owner control over a cryptocurrency wallet. Think of it less like a password and more like the only key to a safety deposit box that has no locksmith. Whoever holds it controls what’s inside. Whoever loses it loses everything.
A seed phrase is a backup of the private key, written as 12 to 24 ordinary words in a specific order. Most wallets generate one when you set up the account. If you lose access to your wallet or device, the seed phrase lets you restore it. It is the last line of recovery.
If your family cannot find either of these after you die, the crypto is permanently inaccessible. Not difficult to access. Not locked pending probate. Gone, in all practical terms, forever.
Chainalysis estimates that around 20 percent of all Bitcoin in circulation is already permanently lost due to lost keys and forgotten credentials. That figure represents billions of dollars sitting in wallets that will never be opened again.
When no one knows the crypto exists
Some people own cryptocurrency and never mention it to anyone. No entry in a will, no note in a drawer, no conversation with a spouse or adult child.
When that person dies, the crypto stays exactly where it is. Exchange accounts sit dormant. Self-custody wallets remain untouched on the blockchain. There is no central registry of cryptocurrency holdings, no equivalent of a bank reporting a dormant account to a regulator.
If a family doesn’t know to look, they won’t find it. And even if they suspect crypto might exist, tracing it requires access to devices, emails, and purchase records that may themselves be inaccessible.
This is not a rare edge case. It’s a predictable outcome when crypto owners treat their holdings as private during their lifetime and make no provision for after their death.
When family knows it exists but cannot get in
In some ways, this situation is harder. A family knows their relative owned Bitcoin. They can see a wallet address on a piece of paper. They may even be able to view the balance on a blockchain explorer. But without the private key or seed phrase, that information is useless. They can see the money. They cannot touch it.
There is no legal mechanism to override this. A probate court can confirm you are the rightful heir. It cannot generate a lost private key. No amount of documentation, legal letters, or formal authority will unlock a self-custody wallet without the original credentials.
The only realistic options are to search thoroughly for stored credentials or, if the crypto was held on an exchange, to contact the exchange directly and begin their formal bereavement process.
Self-custody wallets vs exchange accounts
This is the most important distinction in cryptocurrency inheritance, and it comes down to who actually holds the private key.
Self-custody wallets
With a hardware wallet like a Ledger or Trezor, or a software wallet like MetaMask, you hold the private key yourself. The exchange or software provider does not have a copy. This is sometimes called “not your keys, not your coins,” and it works both ways. If you hold the keys, you have full control. If you lose the keys, no one can help you.
For heirs, recovery is only possible if the seed phrase was stored somewhere accessible, a home safe, a safe deposit box, a sealed envelope with a lawyer. If it wasn’t, the crypto is not recoverable. Not in weeks. Not in years. Not ever.
Exchange accounts
When crypto is held on an exchange like Coinbase or Kraken, the exchange holds the private key on your behalf. You access your account through an email address, password, and usually two-factor authentication. This structure means there is actually someone to call when the account holder dies.
Coinbase has a formal process for handling deceased accounts, including a designated beneficiary feature. Kraken accepts requests from heirs who can provide a death certificate, valid ID, and relevant legal documents. Most major exchanges have some version of this process, though it typically takes four to twelve weeks and requires persistence.
The catch is access to the account credentials. If the email account associated with the exchange has also been lost, or the phone used for two-factor authentication is gone, the process becomes much harder. Families sometimes find themselves trying to recover two accounts at once before they can reach the crypto at all.
What family members can and cannot do
After a cryptocurrency holder dies, there are things family members can do and things that are simply not possible.
On the realistic side: they can contact exchanges with a death certificate and proof of entitlement, search the deceased’s home and devices for written seed phrases or private keys, check safe deposit boxes and any secure storage the person used, look through emails for account registrations, purchase confirmations, or wallet setup instructions, and work with a lawyer if the estate requires formal probate.
What they cannot do is recover a lost private key by any other means. There is no password reset for a self-custody wallet. No court order produces one. No technical expert can reverse-engineer a lost seed phrase. Hiring a cryptocurrency recovery service may sound appealing but most reputable analysis concludes that for standard wallets, if the credentials are gone, the assets are gone.
The Uniform Fiduciary Access to Digital Assets Act, adopted in some form by most US states, gives executors the legal right to access digital assets. But “legal right” still depends on practical access. The law opens the door; it cannot exist without a key.
Common problems families run into
Missing seed phrases account for the majority of unrecoverable crypto estates. People store them on their phone, save them in a notes app, or write them on paper that gets thrown away. Some never write them down at all.
Unknown wallets are also common. A person who bought Bitcoin in 2017 may have set up a wallet they later forgot about, or held accounts on exchanges that have since changed names or gone bankrupt.
Exchange accounts tied to an inaccessible email are a specific and frustrating problem. If the deceased used an email address that no one else can access, and two-factor authentication was set to a phone that’s locked or wiped, recovering the exchange account requires working through multiple layers of account recovery at the same time.
And then there are the assets that are simply gone. Crypto held in a self-custody wallet with no stored seed phrase, no backup, and no surviving record of the private key is not recoverable. Families are sometimes left knowing a wallet exists, watching its balance on a public blockchain explorer, unable to do anything at all.
How to include crypto in your estate plan
The good news is that most of these problems are preventable with straightforward planning.
Start by listing every cryptocurrency account you hold, which exchange it’s on, and roughly what it’s worth. This doesn’t need to be part of your will directly, but your executor should know where to find it.
For exchange accounts, use any beneficiary or legacy contact feature the platform offers. Coinbase’s designated beneficiary service is a good example of how this can work cleanly with proper documentation.
For self-custody wallets, your seed phrase is everything. Store it physically, in a format that won’t degrade, somewhere a trusted person can find after your death. A fireproof safe, a safe deposit box, or a sealed envelope held by your attorney are all reasonable options. Do not store it only in digital form on a device that will be locked when you die.
Write clear instructions for how to use what you’ve left behind. Your family may not know what a seed phrase is or which exchange to contact. Step-by-step guidance, even one page, can make the difference between a recoverable estate and a permanent loss.
Tell at least one trusted person where these instructions are. A plan no one knows about is no plan at all.
Review everything annually. Exchanges update their procedures, you may move crypto between wallets, and your estate picture changes over time.
The Law Society in the UK has published guidance on digital assets in estate planning for solicitors, and the underlying principle applies everywhere: treat your crypto access credentials as seriously as you treat the assets themselves.
What to do right now
- Write down every cryptocurrency account or wallet you currently hold and where it is.
- Locate your seed phrase for any self-custody wallet and store it somewhere physically secure.
- Set up a designated beneficiary on any exchange that offers one.
- Put together a one-page instruction document that explains what you hold and how to access it.
- Tell a trusted person, your executor, spouse, or adult child, where to find your access instructions.
- Add your crypto holdings to your will, at minimum as a reference to a separate secure document.
None of this takes more than an afternoon to set up. For your family, it could be the difference between recovering something valuable and watching it sit permanently out of reach.
