Buying Crypto for Someone Else at an ATM

Short article, because the conclusion doesn't need much building up to.

The short answer

Don't. Converting someone else's cash into crypto and sending it to an address they chose puts you in the one visible position on that chain — your ID, your face, your phone number, your transaction record. The person receiving the coins left none of those.

The payment for doing this is generally small. The exposure is generally not. That ratio tells you what kind of arrangement it is.

You're the visible one

Lay it out:

• The cash — origin unknown to you.
• The verification — your number, your document, your face.
• The CCTV — you.
• The operator's record — in your name.
• The receiving address — theirs, and on-chain it's a string of characters.
• The person — possibly a username and nothing else.

If that money is ever examined, the record shows you arriving with cash of unclear origin, converting it, and sending it to an unidentified address. Asked to explain, you'd say someone asked you to help. What do you have that shows it?

How it gets presented

Rarely as itself. The usual wrappers:

Casual work

"Crypto purchasing agent, paid same day, easy." "One trip, X% commission." Job ads, group chats, comments under videos. The tell is that the pay is out of proportion to the effort and requires no skill.

Someone online needing help

"I'm overseas and can't do it." "My account is restricted." "I'm too old to work these things out." Usually preceded by a stretch of friendly contact. Amounts start small and grow once one has gone smoothly.

A relationship or a mentor

A partner or "teacher" you've known a while, with an opportunity that needs you to move one transaction. Hardest to refuse, because refusing reads as distrust — which is exactly the point of the build-up.

The reverse version

They send you coins and ask you to withdraw cash at a two-way machine and hand it over. Same structure, and now the cash has passed through your hands as well.

"You're only helping, you're not involved"

The standard reassurance. It sidesteps the actual issue, which is that you don't know what the money is or where it's going. "I didn't know" is a reason beforehand and a position afterwards.

Signals that travel together

These requests have a stable shape. Two or more and the conversation can end there.

• Pay out of proportion to effort. A few percent for one trip and some button-pressing. Real errand work doesn't pay like that.
• They avoid meeting. Cash by courier, via a third person, or left somewhere for collection.
• They want your ID and phone number used. If this is fine, why not theirs? Ask it out loud; the answer is usually where it falls apart.
• Heavy emphasis on how simple it is. Minimising complexity is minimising your thinking about consequences.
• Small first, then much larger. The first one is there to build trust and is often paid promptly.
• Time pressure. "Has to be today", "the window closes". Same technique as impersonation scams.
• Keep it to yourself. Reasons vary, function doesn't.

If you met them online

Worth its own note, because the lead-up can run for weeks or months. They become a friend, a partner or a mentor first, and the request arrives only once that's established.

The criteria don't change because you feel close to them. A genuine relationship does not require you to handle cash of unknown origin. And if refusing produces an immediate change of tone or a disappearance, that answers what the relationship was for.

What if it's family

Genuinely different, and worth separating. Helping someone you actually know buy a small amount is not the same as moving money for a stranger.

Even so, two things first.

Check it's their own idea. If an older relative suddenly wants you to pay something at a bitcoin ATM, the question isn't the amount — it's the three questions. They may well be mid-scam, and you'd be the hand that completes it. In practice this is more common than the money-laundering risk.

Check the address is theirs. If it came from "a friend", "support" or "the platform", go back to the first point.

If both clear and they simply want to buy, the better help is doing the arithmetic with them, not the transaction for them. Show them the calculator. What that saves them is worth more than the trip.

What the record actually looks like

The difficulty isn't that you did something obviously wrong. It's that the trail is entirely one-sided, and it stays that way permanently.

Picture what exists afterwards. On one side: a verified identity, a photograph, a phone number tied to an operator account, CCTV, a timestamped transaction, and cash whose origin you never established. On the other: an address on a public ledger, and possibly a messaging handle that stopped responding.

Two features of that make it worse than it first appears.

It doesn't decay. Blockchain records are permanent and operator records are retained for years. A question arising long after you have forgotten the whole thing will still find you at the end of it.

Repetition looks like a pattern. One transaction is an event. Several across weeks, at different machines, with cash you cannot account for, reads as something else entirely — which is exactly why these arrangements always escalate. The small first one is not a trial run for you; it is a trial run on you.

The version that runs the other way

Worth separating out, because people don't recognise it as the same thing: they send you coins, and ask you to withdraw cash at a two-way machine and pass it on.

Structurally identical, with one addition — the cash physically passes through your hands. You are the person the machine identified, the person on camera, and now the person carrying banknotes of unclear origin.

It often arrives with softer framing, too: they can't access a machine, they're not in the country, they'd rather not have an account. The same question applies. Why can't you do it yourself?

If the request came through a platform

These requests circulate through job boards, chat groups, comment sections and marketplaces, and they follow a recognisable pattern that platforms do act on.

• Report it. The next person who sees the post may not have read anything like this.
• Screenshot before reporting. Posts vanish once reported, along with your evidence.
• Don't engage to gather information. Any reply marks you as responsive, and the list gets reused.
• If it came with a real-world contact — an address for collecting cash, a meeting point — that is worth passing to police, not just the platform.

Someone has already asked

• Decline without explaining. "I don't do that" is enough. Explanations give them material.
• Don't agree to "just a small one to test". That is the standard opening, and the amounts escalate quickly.
• Keep the messages. If anything comes of it later, that's what you have.
• Pressure, anger or threats after refusal settle the question. Cut contact.
• Report it if it came via a platform or group. The next person may not have read anything like this.

If you've already done it

Don't panic, but don't ignore it either.

• Stop. Don't do a second one. The most important line here.
• Preserve everything — messages, the address, receipts, transfer records, evidence of what you were paid. What to keep.
• Cut contact, but don't delete the records.
• If the amounts were significant or something feels wrong, speak to a local solicitor. Laws differ a great deal and this page deliberately won't give you a specific answer.

We don't offer legal advice and won't tell you either that it's fine or that it isn't. What we can say is the one thing that decides it: the risk sits with you and the benefit sits with them. Seen clearly, the decision isn't difficult.
