How to Spot a Fake Crypto Exchange or Website (UK, 2026)

Fake crypto exchanges are one of the most effective scams going, because they look identical to the real thing — polished websites, live-updating "balances," professional apps, even small withdrawals early on to build your trust. Then, when you try to take out a meaningful amount, the excuses and "fees" begin, and the money is gone. The single most reliable way to spot a fake in the UK is to check the platform against the FCA register before you deposit anything, and to be deeply suspicious of any exchange that contacts you first or that only one person recommends. A few minutes of checking beats losing your savings.

Scammers have got very good at this. A convincing site is cheap to build, so "it looks professional" tells you almost nothing. Here's what actually matters.

How do fake crypto exchanges work?

They mimic a real exchange, let you "deposit" and watch a balance grow, then block withdrawals when you try to cash out. A typical fake platform looks and feels legitimate: you sign up, deposit crypto or money, and see a dashboard showing your balance rising, sometimes with impressive "profits." To cement your trust, they may even allow a small early withdrawal. It all feels real.

The trap springs when you try to withdraw a significant sum. Suddenly there's a "tax" to pay first, a "verification fee," a "liquidity requirement," or your account is frozen pending some charge. Each fee you pay is more money lost, and no withdrawal ever comes, because the balance was never real. These scams often reach people through social media, messaging apps, "investment" groups, or a too-good-to-be-true tip — frequently linked to the pig butchering and task scam playbooks.

What are the warning signs of a fake exchange?

Not on the FCA register, contacted you first, guaranteed returns, and withdrawal problems. The red flags to check for:

• Not FCA-registered — check the platform against the FCA register; if it's not there, don't use it.
• They approached you — a legitimate exchange doesn't cold-message you on WhatsApp, Instagram, or a dating app to invest.
• Promises of guaranteed or huge returns — real investing never guarantees profits; this is a hallmark of fraud.
• Withdrawal friction — fees, "taxes," or freezes when you try to cash out are the classic tell.
• Pressure and secrecy — urgency to deposit more, or being told to keep it private.
• Only one person recommends it — especially someone you met online.
• Odd details — slightly wrong web address, no real company information, poor English in places, unverifiable team.

Any single one of these warrants stopping. The combination is a scam, near-certainly. Our crypto scams guide covers the wider family of frauds.

How do I verify a crypto exchange is legitimate?

Check the FCA register, verify the exact web address, and stick to well-known, established platforms. The concrete checks before you deposit anything:

1. Search the FCA register for the firm, and check the FCA's ScamSmart warning list.
2. Verify the web address character by character — scammers use lookalike domains (a swapped letter, a different ending).
3. Never use a platform someone messaged you about — go independently to a known, reputable exchange instead.
4. Cross-check reviews from multiple independent sources, not just testimonials on the site itself.
5. Start by trusting nothing — if anything feels off, walk away; there's always another day to invest.

Our best UK exchanges guide lists established, FCA-registered platforms. Sticking to well-known exchanges you found yourself — not ones that found you — removes most of the risk. This isn't financial advice, but it's the discipline that keeps your money safe.

Frequently asked questions

How can I tell if a crypto exchange is fake? Check whether it's on the FCA register (if not, avoid it), verify the exact web address, and be suspicious if it contacted you, promises guaranteed returns, or blocks withdrawals with fees. Fake exchanges look professional, so appearance means little — verification and independent checks are what matter.

Do fake crypto exchanges let you withdraw money? Often they allow a small early withdrawal to build trust, then block larger ones with "taxes," "fees," or account freezes. That early payout is a deliberate hook. When meaningful withdrawals are consistently blocked behind charges, it's a fake platform and the balance isn't real.

How do I check if a crypto exchange is legitimate in the UK? Search the FCA register and ScamSmart warning list for the firm, verify the exact domain for lookalike tricks, cross-check independent reviews, and only use platforms you found yourself rather than ones that contacted you. Stick to well-known, established, FCA-registered exchanges.

Why do fake exchanges ask for fees to withdraw? Because it's the scam continuing — there's no real balance to release. "Taxes," "verification fees," or "liquidity requirements" are invented to extract more money. No legitimate exchange requires an upfront payment to release your own funds. Any such demand means it's a scam; stop paying.

What should I do if I've used a fake crypto exchange? Stop depositing immediately, don't pay any "withdrawal fee," and report to Report Fraud (formerly Action Fraud) and your bank. Recovery is hard once crypto is sent, but reporting matters, and refusing further fees prevents more loss. Beware follow-up "recovery" scams targeting victims. See our crypto scams guide.

The practical next step

Before you deposit on any crypto platform, run the three-second gut check that saves fortunes: did I find this exchange myself, is it on the FCA register, and is the web address exactly right? If it contacted you, promises guaranteed returns, or blocks withdrawals behind fees, walk away. This isn't financial advice. Use an established, FCA-registered exchange from our best UK exchanges guide.
