Common Crypto Scams and How to Spot Them Early
Published 31 July 2026
Crypto scams work because they mimic legitimate things closely. Here are the ones that actually take people's money, and the specific detail that gives each away.
The fake support agent
You post a problem in a public group. Within minutes someone messages you privately, appearing helpful. Eventually they ask for your recovery phrase, your password, or ask you to connect your wallet to a "diagnostic" site.
The tell: they messaged you first. Real support does not do this. Ever. Contact support through the app or the official site only.
The doubling giveaway
"Send 1 BTC, receive 2 BTC back." Often with a hacked verified account and a video of a well-known figure.
The tell: it requires you to send first. Nobody gives away money to strangers. The deepfake videos are now genuinely convincing โ do not use "it looked real" as your test.
Romance and long-con investment
Weeks or months of genuine-feeling friendship, then a mention of a trading platform with excellent returns. Small withdrawals work perfectly. Then you invest more, and withdrawing requires a "tax" or "unlock fee".
The tell: any platform requiring payment before releasing your own money. That is never legitimate. The early successful withdrawals are the bait.
The pump and dump
A coordinated group buys a small coin, promotes it hard, and sells into the buying frenzy. Everyone who arrived through the promotion is left holding it.
The tell: heavy promotion for a coin with no product, and language urging speed. "Get in before it explodes" means the exit is already planned.
The rug pull
A new project raises money, builds hype, and the developers disappear with the funds.
The tell: anonymous team, no working product, returns described as guaranteed. Locked liquidity and a public, accountable team are the minimum bar.
Wrong-network and address-poisoning
Attackers send tiny worthless transactions from an address that looks almost identical to one you use. Later you copy from your history and take the wrong one.
The tell: always copy addresses from the source, never from transaction history, and always verify first and last characters.
The one habit that stops most of it
Slow down. Every scam here depends on you acting before you think. There is no opportunity so good it cannot survive you sleeping on it. If someone is pressuring you to hurry, that pressure is the scam.
