How to Spot Crypto Scams

When you're new to crypto, it's easy to think every shiny token is your next big win. But crypto scams, fraudulent schemes designed to steal your funds under the guise of opportunity. Also known as crypto fraud, they don't need fancy tech—just a convincing story and a countdown timer. The truth? Most scams aren't hidden. They're loud, desperate, and staring right at you in the form of a "limited-time" airdrop, a zero-volume "exchange," or a token with no team and a 99% price crash.

Look at Yum Yum crypto exchange, a fake platform that never existed but tricked users into depositing funds. Or Brawl AI Layer (BRAWL), a token with no code, no team, and a 99.75% drop—built on lies. These aren't outliers. They're textbook cases. A real project has public code, a verifiable team, and trading volume that matches its claims. A scam has a Discord full of bots, a website that looks like it was made in 2017, and promises of 100x returns with no risk.

Then there are airdrop scams, fake giveaways that ask you to connect your wallet or pay a "gas fee" to claim free tokens. The SUNI airdrop, offering 3.5 million tokens to just 850 people, with zero exchange listing and $0 value, is a perfect example. If the token isn't on any exchange and has no utility, it's not a reward—it's a trap. Real airdrops don't ask for your private key. They don't rush you. And they don't disappear after the claim window closes.

You’ll find posts here about dead projects like Fire Lotto, Hero Arena, and Wagmi on zkSync Era—each once hyped, now abandoned. You’ll see reviews of exchanges that vanished, like Bistox, or ones that were never real, like Yum Yum. These aren’t just stories. They’re evidence. The same patterns repeat: no transparency, no liquidity, no updates, and a team that vanishes the moment the money rolls in.

Spotting a scam isn’t about being a tech expert. It’s about asking the right questions: Who’s behind this? Can I verify their identity? Is there real trading activity, or just fake volume? Are they asking for your wallet access? If the answer to any of those is "I don’t know," walk away. The crypto space has real innovation—DeFi tools like Zeta on Solana, AI verification tokens like Mira, and legitimate airdrops like Midnight by Cardano. But those aren’t the ones screaming at you from Twitter ads. They’re quiet, transparent, and built to last.

What follows isn’t a list of warnings. It’s a collection of real cases—each one a lesson. You’ll see exactly how fake exchanges operate, how airdrops turn into theft, and why some tokens crash before they even launch. No fluff. No theory. Just what you need to see before you click "connect wallet."
