What a Bitcoin scam looks like

A Bitcoin scam uses the promise of guaranteed or fast returns to get you to send cryptocurrency to a fraudster, hand over your wallet details, or invest through a fake platform. Contact often comes through social media, a dating app, or an unsolicited call. An example of the style is: Our AI trading bot guarantees 20% weekly returns on Bitcoin. Deposit now and start withdrawing profits within days.

Once a Bitcoin payment is confirmed there is no cancellation or chargeback mechanism, and only the person who received it can choose to send it back. This guide shows the warning signs, how to protect yourself, and what to do if you have already sent crypto.

Why these scams are convincing

Bitcoin's real-world price rises fuel a fear of missing out, and slick platforms with fake trading dashboards showing rising "profits" look genuine. Scammers on dating apps or social media may build a relationship for weeks before introducing the "investment", a pattern often called relationship-investment fraud.

The fact that protects you: a promise of guaranteed or unusually high returns is a serious scam warning, and the FCA says crypto is high risk and you should be prepared to lose all the money you invest.

Signs a Bitcoin opportunity is a scam

• It promises guaranteed, fixed, or unusually high returns.
• You are shown a dashboard with rising "profits" that you can never actually withdraw.
• You are asked to deposit more to "unlock" a withdrawal or cover a fake tax or fee.
• The contact came from an unsolicited call, message, dating app, or social media.
• You are pressured to act quickly, or told the opportunity is exclusive.
• You are asked to move crypto to a wallet or platform you cannot independently verify.
• A "recovery" service later offers to get your lost crypto back for a fee - this is a second scam sign.

How the scam works

First, contact begins through an unsolicited approach, social media, or a dating app. Second, trust is built, sometimes over weeks. Third, you are shown a platform or app with rising profits and encouraged to deposit more. Fourth, when you try to withdraw, you are told to pay a fee or tax first, or the platform simply disappears with your crypto.

Because a confirmed Bitcoin payment cannot be undone, verifying any platform independently before you send anything is the only real protection.

How to protect yourself

Treat a Bitcoin pitch promising guaranteed or unusually high returns as a serious scam warning. Do not send until you have independently checked the firm, the promotion and the receiving party.

• Think about the payment rail before you think about the pitch. Bitcoin itself has no chargeback or cancellation mechanism once a payment is confirmed. A card or bank provider may have a dispute or recovery process of its own, though that is not a simple recall right on an ordinary bank transfer, so sending Bitcoin is effectively the last decision you get to make.
• Do not use a crypto ATM. As checked on 26 July 2026, the FCA says there are no legally operated crypto ATMs in the UK. Check the FCA's current guidance before relying on that status because registrations and rules can change.
• Do not send Bitcoin solely because an online friend, romantic contact, broker or support agent supplied a wallet address. Independently establish who controls it and why payment is due.
• Refuse any "fee" or "tax" charged for unlocking your own profits; paying it usually just funds the next demand.
• Your private keys and recovery phrase go to nobody: not support staff, not a broker, not anyone offering to fix your account.

If you have already sent Bitcoin

Copy the transaction IDs and the destination wallet addresses now. An on-chain record is one of the few pieces of evidence that survives a platform disappearing.

Contact the exchange or app used to make the withdrawal immediately. It may be able to stop a pending withdrawal or flag an account it controls, but a confirmed payment to a self-hosted wallet cannot be reversed by the exchange. Preserve the transaction ID, wallet address, account history and messages for the provider and investigators.

Be realistic about what follows. Much of the useful work is closing off the accounts and identity exposure around the loss — the scam recovery checklist sets those steps out in order.

How to report a Bitcoin scam (UK)

Report it first to the provider you actually used to send the funds, and give it the transaction IDs and destination addresses. A custodial exchange or app may be able to halt a pending withdrawal or restrict an account it controls; a non-custodial wallet service may have no account to act on at all.

Tell the Financial Conduct Authority about the investment platform or the promotion behind it, using its financial promotion form for an authorised firm or its scam contact route and consumer helpline on 0800 111 6768 for a suspected unauthorised or clone firm.

Then file the loss itself through the national fraud route: reportfraud.police.uk or 0300 123 2040 in England, Wales and Northern Ireland, and Police Scotland on 101 in Scotland. Scam emails and texts have their own forwarding routes, set out in the scam recovery checklist.
