Ten years away from your crypto, and what's still there

Quick answer: Coins in a wallet you control are still there in ten years, provided you still have the seed phrase. Coins on an exchange depend on three things: the company surviving, your email still working, and your state's unclaimed property rules.

Ten years is a long time to be gone. Think of a guy who buys some bitcoin, moves overseas for work or gets buried in a family crisis, and surfaces in 2036 with a decade of dust on everything. What he finds depends almost entirely on one question he answered, or didn't, back at the start. Where do the coins actually live?

The wallet that doesn't care what year it's

If you hold your own keys, the blockchain doesn't know you left. Nobody charges an inactivity fee. Nobody closes the account. The coins sit at their address, and the network doesn't expire them.

What you need to get back in is the seed phrase, usually 12 or 24 words, written in order. That's the whole key. The hardware wallet, the app and the phone are all replaceable. If the device died in a drawer, you can typically restore the same coins on a new one using the phrase.

The weak points are all human:

• The paper. Ink fades. Basements flood. A phrase written on a sticky note and moved twice isn't a plan. Plenty of people use a stamped metal plate for this reason.
• The location. If the phrase is in a safe only you can open, and you're not around, it's gone. See the biggest threat to your crypto is your own filing system for how people lose coins without ever being hacked.
• The details. Some wallets add an extra passphrase on top of the 24 words. Forget it and the words alone open nothing. Write down that one exists.

Self-custody is the liberty option. It's also the one where nobody can rescue you. That's the deal.

The exchange account that does care

Leave coins on a custodial exchange for a decade and you're depending on a long chain of things staying put. Any one of them can break.

Your email. Every password reset, every notice, every "your account is inactive" warning goes to the address on file. Some email providers delete accounts after long inactivity. If yours does, the front door to the exchange goes with it. Check your provider's policy before you vanish, not after.

Your phone number and your second factor. The authenticator app lived on a phone you no longer own. The number was reassigned. Most exchanges will let you recover through identity verification, but expect to dig up a current government ID, and expect it to take weeks, not minutes.

The company. Exchanges get acquired, change their terms and shut down. Some have failed outright. When FTX and Celsius collapsed in 2022, customers who hadn't touched their accounts were in the same line as everyone else, waiting on a bankruptcy process. Ten years is a long time to bet on a company staying healthy.

The inactivity rules. Read the terms of service. Some platforms reserve the right to charge fees on dormant accounts or close them. That's the contract you agreed to, whether you remember clicking it or not.

Your state. This is the one that surprises people. Every state has unclaimed property law, and financial accounts that sit untouched with no contact for a set period can be turned over to the state. The dormancy period and the treatment of crypto vary by state and keep being updated. In some cases the state may sell the assets and hold the cash value as of that day, not the coins. If bitcoin tripled after that sale, you'd get the old number.

If it happens, the money isn't gone. You can search your state's unclaimed property office, and many states feed into MissingMoney.com. But you'd be claiming dollars, not the asset you thought you owned.

The in-between cases

Some people aren't purely in either camp.

Staking and lending are the first. Coins locked in a staking contract or lent out for yield keep running without you. That can be fine. Terms can also change, and platforms can freeze withdrawals.

The second is the one that ends badly: a position backed by borrowed money. If you borrowed against your crypto and the price fell while you were gone, the lender can sell your collateral automatically. Nobody sends a letter first. If you're going dark for a long stretch, don't leave a loan open against your coins.

Before you go

If you know you'll be unreachable, an hour of work covers most of this.

1. Decide where the coins live. For long storage, most people are better off with their own wallet and a properly stored seed phrase. Move a small test amount first and confirm you can see it arrive.
2. Write the recovery steps down. Where the phrase is, whether there's a passphrase, which wallet software restores it. Plain language, as if for somebody who's never touched crypto.
3. Tell one trusted person. Your wife, an adult child, a brother. They don't need the keys today. They need to know the keys exist and where to ask. A sealed letter in a safe-deposit box or with your attorney works.
4. Fix your email and phone. Make sure the address on every account is one that'll still be alive. Keep the number.
5. Talk to an estate attorney and a tax professional. Crypto and inheritance, and what counts as a taxable event if an account is liquidated, are state-specific questions. A general article can't answer them for your situation.

None of this is complicated. Most people skip it because it's boring and nobody's asking.

Coming back

If you walk back into this after years away, slow down. Start with the email account. Recover that first, because everything else flows through it. Then check your state's unclaimed property listings for anything that got swept up.

And be careful who you ask for help. People who've been gone a long time and are suddenly searching "how to recover my crypto" are a favorite target, and fake support numbers and "recovery services" are everywhere. The crypto scams that catch careful people too is worth ten minutes before you click anything. And if you're mostly trying to get your bearings on the market itself, catching up on bitcoin after ignoring it for ten years is a good place to start.

A blockchain can wait a decade without blinking. Companies, inboxes and phone numbers can't, and neither can your memory. Protect those, and write a letter to the people who'd have to carry it if you couldn't.
