This is history, not a forecast. Past performance is not a guide to future returns. Capsule balances are investments, not deposits, and are not covered by any deposit-guarantee scheme.
One bitcoin was €11,795 at the end of 2017 and €54,195 today. Year-end BTC/EUR closing prices, after every Till18 fee.
Euros go in. Bitcoin is what waits. Your child gets both the money and the letters.
Nobody in your family ever holds a coin, picks a price, or opens an exchange account. The capsule does one thing, in one direction, for eighteen years.
Euros, by card or transfer
Grandparents and relatives open your gifting link and give in the currency they think in. No app, no account, under a minute.
Bitcoin, bought once
Each gift is converted the day it arrives and stays converted. No trading, no rebalancing, no decisions to make later.
Everything, at 18
Your child proves who they are, takes full ownership, and reads eighteen years of letters before the balance appears.
Why Bitcoin is the first capsule.
It carries the whole promise on day one
A Bitcoin capsule needs no interest to pay, so it needs no partner to keep paying it. Everything we promise — one-way deposits, family-held keys, recovery without us — is true from the first euro, not once someone else signs a contract.
Eighteen years is the horizon it was built for
Gifts arrive across nearly two decades, at many different prices, from many different people. That is the opposite of betting on one moment, and it is exactly how a capsule fills.
It is the gift people already understand
“We put away some Bitcoin for her eighteenth” is a sentence a grandparent can repeat at a birthday table. The mechanism can be sophisticated; the story shouldn’t need explaining.
The seal does the hardest part
Long-term money usually fails for human reasons: a scare, a dip, a good excuse. Here there is no withdraw button for anyone, so the plan you make on day one is the plan that survives to their birthday.
In plain words: what the capsule actually holds.
Most companies would leave this on a technical page. It belongs here, because it is the part a careful parent should ask about.
Your capsule holds cirBTC: Circle’s bitcoin on Circle Arc, the network the capsule contract runs on. One cirBTC represents one bitcoin, issued and redeemable by Circle: the company behind USDC, listed on the New York Stock Exchange since 2025 as NYSE: CRCL.
We chose it because it is the only way, today, to get all three things in one place: a lock that a smart contract enforces rather than a policy, keys your own family holds, and a gifting link a grandmother can use on the first try. Bitcoin on its own network cannot do the second and third at once without asking your relatives to run software none of them wants to run.
It is not coins sitting in a wallet you operate on the Bitcoin network. That is a real difference, and these are its edges: Circle can freeze tokens under a court order, and Arc is a young network that reached mainnet in 2026. Neither power belongs to Till18, and neither can hand your child’s money to anyone else.

Would your family rather hold something else?
Euro and Dollar capsules are coming soon. They hold regulated euro and dollar stablecoins, so no bank holds your child’s money and no bank can close the account, lend it out, or fail with it in hand — and they earn interest while they wait, of which we keep one euro in five. That interest comes from lending markets, so it moves with them rather than being fixed like a bank rate.
A stock index capsule follows them, for families who would rather their child’s eighteen years tracked the market as a whole.
One capsule holds one asset — it never switches under you. Families who want both simply open two capsules for the same child, and every gifting link says which capsule it fills.

What a Bitcoin capsule costs, in full.
No subscription, no yearly fee on the balance, and no fee that can ever stand between your family and the capsule.
| Item | Price | The honest detail |
|---|---|---|
| Opening, depositing, recovery | Free, forever | No fee ever gates your custody or the emergency path. |
| Buying the capsule’s Bitcoin | 0.75% of each deposit | Charged once, when euros become Bitcoin. Never again on money already inside, and already deducted from every figure on this page. |
| Gift by card | €1.99 flat | Paid by the giver, shown before they pay. Never a percentage of the gift. Bank transfer is free. |
| Holding it for eighteen years | €0 | A Bitcoin capsule earns no interest, so there is no yield for us to share and no annual fee to charge. We earn when money goes in, not while it sits. On the Euro and Dollar capsules, which do earn interest, we keep one euro in five of what is earned and never touch the deposits. |
| Unsealing at 18 | Free | Taking self-custody is always free. If your child asks us to handle identity checks and pay-out to a bank account, that service costs 0.5% capped at €100 — waived if they keep the money with Till18. |
Questions parents ask about this capsule, answered plainly.
Will my child have to know anything about crypto?
No. There is no trading, no tokens to choose, no app for kids, and nothing for anyone to manage while the capsule is sealed. Your family gives euros; at 18 your child receives what the capsule holds, with a step-by-step claim we walk them through.
What if the market is down when they turn 18?
A Bitcoin capsule can go down as well as up, and we would rather say that plainly than bury it. What an eighteen-year horizon buys you is time, and gifts arriving across nearly two decades at many different prices — the opposite of betting on one moment.
If your family would rather hold something steadier, the Euro and Dollar capsules coming soon are built for exactly that, and they earn interest while they wait. One child can have more than one capsule.
Can we change the capsule to euros later?
No, and that is deliberate. One capsule holds one asset for its whole life, so nobody — including a future version of us — can quietly change what your child was promised. If your plans change, open a second capsule alongside the first; both open on the same birthday.
Who can take the Bitcoin out before 18?
Nobody, and that includes you and us. There is exactly one withdrawal path and it belongs to your child, after the unlock date. The single exception is the emergency valve: a majority of the guardians you appointed, a 60-day public notice, and a veto for any one of them.
What happens to the Bitcoin if Till18 closes?
It stays exactly where it is. The capsule is a contract on a public network, your family holds the keys, and the recovery kit you print at sealing opens it without our app, our servers, or our company. Every family rehearses that once, on purpose, the week they seal.
Is a gift taxed, and who declares it?
Gifts to a child are treated differently in every country, and we are not your tax adviser. What we do is keep a complete, dated record of every gift and every fee from the first euro, so whoever advises you has real numbers to work from.
Their 18th birthday is already on the calendar.
Setting one up takes ten minutes. We open capsules in small groups so every founding family gets a real conversation.
For parents and guardians (18+). One email to confirm, one when your capsule is ready — nothing else.
iPhone and Android apps arrive with the first capsules. Everything works in a browser on day one.
