How to check if a cryptocurrency website is fake

Short answer

Check a cryptocurrency website by verifying the exact domain and its registration age, searching the FCA Warning List and register, testing whether a small withdrawal actually completes, and confirming the company at Companies House. Fake platforms typically show rising balances, block withdrawals behind fees, and use domains registered within the past few months.

Fraudulent trading and investment sites are cheap to build and increasingly polished. The checks below take a few minutes each, cost nothing, and catch the great majority of them before any money moves.

Check the domain, not the design

  • Look up the registration date with a public WHOIS lookup. A platform claiming years of history on a domain registered last month is misrepresenting itself.
  • Read the address character by character. Substituted letters, extra hyphens and unusual endings are used to imitate a known brand.
  • Check whether the same page text appears on other domains — copied sites are usually deployed in batches.

Check the company behind it

A UK firm should name its registered company and number, and that record should be searchable on the Companies House register with a matching name and address. Check the FCA register and Warning List for anything presented as a regulated investment. A named company you cannot find anywhere official is a clear signal to stop.

Check how withdrawals are described

  • Any requirement to pay a fee, tax or deposit before a withdrawal is released is not a legitimate arrangement.
  • Minimum balances or trade volumes that must be reached before funds can be taken out are a common control mechanism.
  • Rising displayed profits that cannot be withdrawn are simply numbers on a page.

Check how they contact you

Consider how the approach reached you. Unsolicited contact through a dating app, a group chat, or a message that opened as a wrong number is the most common route into this kind of fraud. A named account manager who moves the conversation to a private messaging app, and who applies time pressure, is following a script rather than serving you.

Check the claims

  • Guaranteed or fixed daily returns do not exist in any legitimate market.
  • Testimonials with stock photography and no verifiable source are generated, not collected.
  • Certificates, licences and audit documents shown as images should be verified with the issuing body directly, never through a link the site provides.

If you have already deposited

Stop paying, preserve the record — transaction IDs, addresses, chat logs and screenshots — and report it. Our guide on the first steps after sending cryptocurrency to a fraudster sets out the order to work through.

If you are looking at your own case rather than reading generally, our cryptocurrency investigation service explains how a case is scoped and worked, the asset tracing hub covers the network-specific work, and our overview of cryptocurrency scam recovery in the UK sets out what is realistic.

Common questions

Does an HTTPS padlock mean a site is genuine?
No. Certificates are free and automatic. The padlock confirms the connection is encrypted, nothing about who is running the site.
Are app store listings a reliable signal?
Not by themselves. Fraudulent apps do get published, and many of these platforms are web apps installed through a link rather than a store.
The site let me withdraw a small amount. Is it genuine?
Not necessarily. A small early withdrawal is frequently allowed to build confidence before a larger deposit is encouraged.
