How to spot a crypto scam before you send funds
How to spot a crypto scam using five checks: unsolicited contact, guaranteed returns, withdrawal friction, address mismatches, and urgency pressure.
How to spot a crypto scam comes down to checking five things before you send a single transaction: who contacted whom, whether returns are guaranteed, whether you can withdraw small amounts freely, whether the receiving address matches what you expect, and whether you're being rushed. Miss any one of these and the other four won't save you.
Who reached out first?
Legitimate exchanges, wallets, and projects don't cold-message you on Telegram, WhatsApp, or Instagram with investment opportunities. If a stranger added you to a group chat, commented on your post about crypto, or "wrong-numbered" you into a friendly conversation that somehow led to a trading platform, that's the single most reliable scam signal there is. The FBI's Internet Crime Complaint Center logged $5.6 billion in crypto fraud losses for 2023, and pig-butchering schemes that start exactly this way accounted for a large share of it, according to the FBI's 2023 IC3 report. Real opportunities don't need to find you first.
Are the returns too clean?
Any pitch promising a fixed daily or weekly percentage, "guaranteed" APY above what you'd get from staking a major asset (roughly 3-6% for ETH, less for BTC), or a dashboard showing your balance climbing on a steady line with no volatility, is describing a return profile that doesn't exist in real markets. Crypto is volatile by nature. A platform that shows zero drawdown is showing you fiction, usually a number in a database, not an actual position. Ask yourself what trade, protocol, or business generates that yield, and if the answer is vague ("arbitrage," "AI trading bot," "market making") treat it as no answer at all.
Can you actually withdraw?
This is the test that catches most people too late, because scammers let early withdrawals succeed. Someone deposits $500, withdraws $520 a week later, gets convinced, and deposits $20,000. That second withdrawal never clears. Before committing real money, test with the smallest amount the platform allows, and try withdrawing it the same day. If the platform stalls with a "compliance review," demands a tax payment before releasing funds, or asks you to deposit more to "unlock" your existing balance, stop. Legitimate platforms never charge a fee to let you access money that's already yours.
Does the address match what you're sending to?
Wallet drainers and fake support scams rely on you not double-checking the destination. Before confirming any transaction, verify the first 4 and last 4 characters of the receiving address against the source you trust, not against a link someone sent you. Check that the domain in your browser bar matches the real project (watch for swapped letters, extra hyphens, or a ".io" where the real site is ".com"). If a browser wallet pop-up asks for a signature you don't understand, especially one from a site you reached through a DM link rather than typing the URL yourself, decline it. Signature phishing that drains a wallet in one approval has cost individual victims six and seven figures in a single click.
Why the rush?
Scarcity and urgency are the oldest tools in the kit, and they work because they short-circuit the pause where you'd normally check. "This offer closes in 2 hours," "the price doubles at midnight," "send now or lose your spot," all of these are designed to get money moving before your skepticism catches up. A real investment, airdrop, or presale can survive you sleeping on it for a night. If it can't, that's the point.
What to check before you send anything
Search the project name plus "scam" or "review" before depositing. Look up the contract address on a block explorer and check whether it's verified and whether liquidity is locked. If someone claims to be from an exchange's support team, go directly to that exchange's official site and open a ticket yourself rather than replying to their message. And treat any unsolicited contact, no matter how long the relationship has developed, as reason enough to slow down. The pattern matters more than the platform: scams evolve their branding constantly, but the five signals above stay the same.
