How to Spot Crypto Scams: Common Tactics and a Rug-Pull Checklist

Direct answer: Crypto scams share a signature: "abnormal high returns + manufactured urgency + asking you to move assets or reveal keys." Remember one iron rule — anything guaranteeing returns, anything asking for your seed phrase, anything rushing you to "pay now" is almost 100% a scam.

Four most common tactics

1. Pig butchering Scammers build trust on social/dating apps ("fattening the pig"), then steer you to a convincing-looking "investment platform." They let you profit and withdraw early to earn trust, then lure a large deposit — after which the platform vanishes and your principal goes to zero. Tell-tale: any "insider high-yield channel" recommended by an online romance or stranger is 100% a trap.

2. Rug pulls (money goes in, never out) A new token attracts buyers, but the contract hides "buy-only, can't-sell" code, or the team suddenly pulls all liquidity and runs. Tell-tale: before buying, check whether the contract is open-source and audited, whether liquidity is locked, whether the team is anonymous, and whether a small test sell goes through.

3. Fake airdrops / phishing sites "You have an airdrop to claim" links to a fake site that asks you to connect your wallet and "sign" — that signature actually authorizes the scammer to drain your assets. Tell-tale: don't touch airdrops from unknown sources; verify the URL before connecting; periodically revoke suspicious approvals with an allowance checker.

4. Support impersonation / fake officials Fake "exchange support" or "wallet support" contacts you, citing "account issues" or "help unfreezing" to extract passwords, codes, or seed phrases. Tell-tale: no real support agent DMs you or asks for your seed or codes. Official channels use in-app tickets/official sites only.

Pre-buy checklist (run through it before any new coin)

1. Returns abnormal? Promises of "guaranteed profit," "principal-protected high yield," or "X% daily" — walk away.
2. Rushing you? "Limited time," "ends now," "miss it forever" is standard impulse-baiting.
3. Asking for keys/seed? Anyone requesting your seed — block immediately.
4. Can the token be sold? Test with a small buy and a sell to detect rug code.
5. Project transparency? Open-source audited contract, locked liquidity, doxxed team, a real product?
6. Source of the tip? A stranger's "insider rec" is essentially a death sentence.

Use tools to help judge

New coins are high-risk. Use Altcoin Health to screen liquidity and rug risk, and Exchange Reserve for exchange solvency. But tools are only aids — your last line of defense is your own common sense: if it's too good to be true, it isn't true.

The details people miss

The most insidious scams aren't crude fake sites — they're polished pig-butchering operations with "real trading interfaces" that genuinely let you withdraw early. They exploit greed and trust; the tech is secondary. Best protection: use large compliant exchanges, self-custody large holdings, never give your seed to anyone, and keep an instinctive skepticism toward "high-yield insider channels."

Trade on major exchanges and cut costs for real with rebates — far more reliable than chasing "high-yield" scams.
