Scammers love crypto because transactions are irreversible. Here are the most common tricks, how to recognize them, and what to do if you're targeted.

Why crypto attracts scammers

Three properties make crypto a scammer's playground: transactions are irreversible, pseudonymous (hard to trace to real identities), and global (no jurisdiction can easily freeze funds). If someone tricks you into sending crypto, it's gone.

The most common scams

1. Seed phrase phishing

You receive a DM, email, or see a website that looks like MetaMask, Ledger, or an exchange. It asks you to "verify" or "restore" your wallet by entering your seed phrase. The moment you type it in, your wallet is drained.

Rule: No legitimate service will ever ask for your seed phrase. Ever. If something asks for it, it's a scam. No exceptions.

2. Fake token scams

Someone creates a token with the same name as a popular project (fake PEPE, fake ARB). It shows up in your wallet unexpectedly, with an enticing value. When you try to sell it, the smart contract either steals your real tokens or asks you to approve unlimited spending.

Rule: If tokens appear in your wallet that you didn't buy, don't interact with them. Don't try to sell them. Just ignore them.

3. Impersonation scams

Someone pretends to be a support agent, developer, or influencer on Discord, Telegram, or X. They offer to "help" with an issue — but the help involves you sharing screen, connecting your wallet to a fake site, or sending crypto to "verify" your account.

Rule: Real support never DMs you first. Real developers never ask for your keys. Real influencers never guarantee returns.

4. Rug pulls

A new project launches with big promises and a liquidity pool. Early buyers push the price up. The team then removes all liquidity from the pool and disappears. Token holders are left with a worthless asset and no way to sell.

Rule: Check if liquidity is locked. Check if the team is doxxed. Check the contract on RugDoc or similar tools. If you can't verify any of these, don't invest.

5. "Send me 1 ETH, I'll send back 2"

Sounds absurd, but these scams work because they impersonate famous figures (Elon Musk, Vitalik Buterin) during live streams or on social media. The setup looks convincing — professional graphics, fake verified accounts, and thousands of fake comments.

Rule: Nobody gives away free crypto. If it sounds too good to be true, it is.

6. Fake exchange/wallet apps

Cloned apps appear in app stores or as Google ads. They look identical to real exchanges but steal your login credentials and any funds you deposit.

Rule: Always download from official links on the project's verified website. Bookmark them. Don't trust search results or ads.

7. Romance/investment scams

Someone builds a relationship with you online, then introduces you to a "guaranteed" crypto investment platform. You deposit and see "profits." When you try to withdraw, you're asked for more money (taxes, fees, verification). The platform is fake, and everything you deposited is gone.

Rule: If someone you met online asks you to invest in crypto, it's a scam. Every time.

General protection habits

  • Use hardware wallets for significant holdings
  • Enable 2FA everywhere (authenticator app, not SMS)
  • Never click links in DMs or unsolicited emails
  • Revoke unused token approvals regularly
  • Use a dedicated email for crypto
  • If in doubt, don't interact. Walk away and research independently.
