How to Spot Crypto Scams: Red Flags Every Investor Should Know
Protect yourself from rug pulls, phishing, Ponzi schemes, and fake token scams. Practical red flags and verification steps.
Crypto scams cost investors billions every year. The decentralised and pseudonymous nature of blockchain makes it attractive to fraudsters. Here are the most common scams and how to protect yourself.
Rug pulls
A rug pull happens when a project's creators abandon it and run off with investor funds. Warning signs include anonymous teams with no verifiable track record, unaudited smart contracts, locked liquidity that unlocks soon, and aggressive marketing with unrealistic promises. Always check if the token's liquidity is locked and for how long. If the team can remove liquidity at any time, your investment is at risk.
Phishing attacks
Phishing is the most common attack vector. Scammers create fake websites that look identical to legitimate DeFi protocols, exchanges, or wallet providers. They spread these links through fake social media accounts, Discord messages, and email. Always verify the URL carefully — scammers often use similar-looking domains. Never enter your seed phrase into any website. No legitimate service will ever ask for it.
Ponzi and pyramid schemes
If a project promises guaranteed returns — especially high fixed percentages like "1% daily" or "guaranteed 10x" — it is almost certainly a Ponzi scheme. These projects pay early investors with funds from later investors. They always collapse eventually, and most participants lose money.
Pump and dump schemes
Coordinated groups buy a low-cap token, create hype through social media and paid influencers, then dump their holdings when the price spikes. By the time retail investors buy in, the insiders are selling. Be especially wary of tokens being heavily promoted in Telegram groups and by influencers who do not disclose their holdings.
How to protect yourself
Verify contracts on Etherscan — check if the code is verified and audited. Use our wallet age checker to see if the deployer wallet is brand new (a red flag). Research the team — anonymous teams are higher risk. Start small — never invest more than you can afford to lose in any single project. Use hardware wallets for significant holdings. And remember: if something sounds too good to be true, it almost certainly is.
