Can Under-18s Buy Crypto in the UK? A Parent's Guide (2026)

Under-18s cannot open an account on a regulated UK crypto exchange — the minimum age is 18, because of the identity, anti-money-laundering, and contract rules platforms must follow. But a teenager can still own crypto: a parent or guardian can legally buy and hold it on their behalf. So the honest answer to "can my 16-year-old buy Bitcoin?" is no, not directly on a proper exchange — but yes, you as a parent can do it for them, with some real risks and a tax wrinkle worth knowing. Beware, too, that the "workarounds" teenagers find online often lead straight into scams.

As a parent, the instinct to nurture a curious teen's interest is a good one. The key is doing it safely and legally, rather than letting them chase risky back doors.

Can a teenager open a crypto account in the UK?

No. Regulated UK crypto exchanges require account holders to be 18 or over, so a minor can't legally open or operate one in their own name. This isn't the exchange being awkward — it stems from money-laundering rules, identity verification requirements, and the fact that contracts with minors are hard to enforce. Every reputable, FCA-registered platform enforces the 18+ rule.

That means the "buy crypto under 18" tricks floating around online — using someone else's ID, unregulated platforms, gift cards, crypto ATMs, or dodgy P2P deals — range from rule-breaking to outright dangerous. Crypto ATMs are illegal in the UK entirely, and unregulated or P2P routes expose a young person to fraud with no protection. The safe path isn't a workaround; it's a parent acting on their behalf.

How can a parent buy crypto for a child?

A parent or guardian can buy crypto in their own name and hold it for the child, keeping legal control until the child is old enough. Practically, you open an account on an FCA-registered exchange as the adult, buy the crypto yourself, and treat it as held for your child — informally, or more formally through a trust or bare-trust arrangement if the sums are meaningful. The adult remains legally responsible for the account and the asset.

This lets a teenager benefit from — and learn about — crypto without breaking any rules. Many parents use it as a teaching tool: a small, affordable amount to demonstrate how volatile and risky crypto is, alongside the security basics in our self-custody guide. Keep it small; crypto is high-risk and unregulated with no FSCS protection, and a teenager's first lesson should be that it can fall as fast as it rises. Our how much to start guide is a sensible frame.

Are there tax implications for parents?

Yes — the crypto is generally treated as the parent's for tax while held in the parent's name, and gains can be taxable. This is the wrinkle people miss. If you buy and hold crypto in your own name for your child, disposals (selling, swapping, spending) are your taxable events, counting toward your £3,000 annual capital gains allowance, not the child's. There are also anti-avoidance rules where parents gift income-producing assets to children, though crypto's treatment turns on the specifics.

If you want the crypto to genuinely be the child's for tax, that usually needs a proper structure like a bare trust — an area where advice pays off. Either way, keep clear records of what was bought, when, and for whom. Our gifting crypto tax guide and capital gains guide cover the mechanics. This isn't tax advice; for anything beyond small sums, speak to an accountant.

Frequently asked questions

Can a 16-year-old buy Bitcoin in the UK? Not directly on a regulated exchange — the minimum age is 18. A 16-year-old can, however, own crypto that a parent or guardian buys and holds on their behalf. Online "workarounds" to buy under 18 are risky, often rule-breaking, and a common route into scams.

Why is the crypto age limit 18 in the UK? Because regulated exchanges must perform identity and anti-money-laundering checks and enter enforceable contracts, which rules out minors. It's a legal and regulatory requirement, not just a platform preference, and every FCA-registered exchange applies it.

Can I buy crypto for my child? Yes. As a parent or guardian you can buy crypto in your own name and hold it for your child, retaining legal control. For meaningful amounts, a formal structure like a bare trust may be appropriate. Keep records, and treat it as a small, high-risk teaching tool.

Who pays tax on crypto held for a child? Generally the parent, while the crypto is held in the parent's name — disposals count as your taxable events against your allowance. Making the crypto genuinely the child's for tax usually requires a trust structure. Keep records and consider professional advice for larger sums.

Is it safe for teenagers to get into crypto? Only with adult oversight and small, affordable amounts. Crypto is volatile, unregulated, and heavily targeted by scams aimed at young people. Used carefully as a teaching tool, it can build financial understanding; used via risky workarounds, it can cause real harm.

The practical next step

If your teenager is keen, don't let them chase risky back doors — buy a small, affordable amount yourself on an FCA-registered exchange and use it to teach them how volatile and scam-prone crypto really is. Keep records for tax, keep it small, and get advice before anything substantial. This isn't tax or financial advice. To set a sensible amount, read our how much to start guide.
