How to Avoid Crypto Exchange Scams

October 15, 2026  ·  7 min read

Cryptocurrency scams cost users billions of dollars every year. Unlike traditional finance, blockchain transactions are irreversible — once your funds leave your wallet, there is no chargeback, no fraud department, and usually no recovery. Knowing the most common attack vectors is your first line of defence.

1. Fake Exchange Websites (Phishing Clones)

Scammers build pixel-perfect copies of popular exchanges and promote them via Google Ads, fake social media accounts, and email campaigns. The URLs differ by one character:fixedf1oat.com instead of fixedfloat.cv, or a homoglyph substitution that is invisible at a glance.

Red flags: URL doesn't match the exchange's official domain; SSL certificate issued to an unfamiliar entity; site arrived via a paid ad (not an organic search result); page asks for a seed phrase or private key.

Protection: Bookmark the official URL the first time you use a service. Never navigate to an exchange by clicking ads — go directly from your bookmark. Double-check the domain in the browser address bar before every transaction.

2. Fake Mobile Apps

Both the Apple App Store and Google Play have hosted counterfeit exchange apps that look identical to the official ones. They capture your login credentials or seed phrase during setup.

Red flags: Low download count for a supposedly popular app; publisher name slightly different from the official one; reviews mention "deposit didn't arrive" or "can't withdraw."

Protection: Only download apps linked directly from the exchange's official website. Verify the developer name matches exactly. For instant exchanges like FixedFloat, there is no account or login — a mobile app is not needed at all.

3. Honeypot Tokens

A honeypot is a smart contract designed so that anyone can buy the token butcannot sell it. The contract includes a hidden sell restriction that only the deployer can override. Victims watch the price rise, buy in, then find their tokens permanently locked.

Red flags: Token promoted aggressively in Telegram groups; no audit from a reputable firm; very recent contract deployment; zero or negligible sell transactions in the on-chain history.

Protection: Before buying any new token, check the contract on a token scanner (Honeypot.is for EVM chains). Look for sell tax set to 100% or transfer restrictions. Only invest in tokens with verified contracts and audits.

4. Rug Pulls

In a rug pull, project developers raise funds (via token sale, liquidity provision, or presale), then abruptly withdraw all liquidity and disappear. The token price crashes to zero in seconds.

Red flags: Anonymous team with no verifiable identity; no locked liquidity; vague or plagiarised whitepaper; unrealistic APY promises; heavy pressure to invest quickly before "it's too late."

Protection: Check whether liquidity is locked (via Team Finance or Unicrypt). Research the team — pseudonymous is acceptable, completely anonymous with no track record is not. Never invest more than you can afford to lose in new DeFi protocols.

5. Social Engineering — "Pig Butchering" Scams

The pig butchering scam (shā zhū pán) is one of the most financially devastating scam types. Scammers build a romantic or friendship relationship over weeks or months via dating apps or social media, then introduce a "can't-lose" crypto investment platform. The platform shows fake profits to encourage larger deposits — until the victim tries to withdraw and finds their funds inaccessible.

Red flags: New online contact immediately steers conversation to investing; investment platform not listed on CoinGecko or major aggregators; profits too consistent to be real; "tax fee" required to withdraw.

Protection: Never invest in any platform introduced by someone you only know online. Verify every exchange independently. Legitimate platforms never require fees to access your own funds.

6. Fake Customer Support

On Telegram and Discord, scammers impersonate support agents of well-known exchanges. They DM users who posted questions in public groups, offering to "resolve" the issue — and asking for wallet access, seed phrases, or a deposit to "verify" the account.

Red flags: Support agent initiates contact with a DM; asks for your seed phrase, private key, or remote screen access; asks you to send a "verification transaction."

Protection: Legitimate support never DMs first. Never share a seed phrase with anyone — no support agent at any real company will ever ask for it. Use official support channels listed on the exchange's website only.

General Safety Rules

• Bookmark official URLs — never navigate via ads or search result clicks
• Test with small amounts first on any new platform
• Use hardware wallets for large holdings (Ledger, Trezor)
• Never share your seed phrase with any person or website
• Verify contract addresses only from the project's official site or CoinGecko
• Enable 2FA on all custodial accounts

Why Non-Custodial Exchanges Are Safer

FixedFloat is a non-custodial instant exchange — it never holds funds in user accounts. There is no account to compromise, no stored balance to drain, and no login credentials to phish. Each exchange order is a one-time transaction directly between blockchains. Your funds go from your wallet to the exchange's deposit address, then immediately to your destination wallet — no intermediate custody.
