How to Spot a Crypto Scam

Introduction

For every genuine crypto project, a dozen look‑alike scams pop up—rug pulls, phishing dApps, fake airdrops. The good news? Most cons share the same tell‑tale signs. Learn them once, and you’ll slash your risk forever.

1. “Guaranteed Returns” Promises

Any project promising fixed, double‑digit yields or “risk‑free profits” is waving a giant red flag.

  • Case Study: Bitconnect 2.0 (2023) promised 1 % daily returns—collapsed within months, losing users $40 million.
  • Quick Check: Search the project + “guaranteed returns scam” before investing; legitimate projects never promise set profits.

2. Anonymous or Fabricated Team

Do the founders hide behind cartoon avatars? Are LinkedIn profiles less than six months old?

  • Case Study: Squid Token (2021) used fake dev bios; price rose 45,000 % then crashed to near‑zero.
  • Quick Check: Look for independent interviews, recorded conference appearances, or GitHub activity.

3. No Audit, No Code Transparency

Smart‑contract projects should link to audits or open‑source code.

  • Case Study: Meerkat Finance (2024) launched on BNB Chain with no audit; $32 million vanished via a hard‑coded backdoor.
  • Quick Check: Verify contracts on Etherscan or BSCScan, read the audit PDF, and confirm it’s from a reputable firm.

4. High‑Pressure Marketing & Referral Schemes

Scams urge you to “buy before midnight” or reward you for recruiting friends.

  • Case Study: PlusToken (2019) offered tiered referral bonuses; its founders fled China with $2 billion in crypto.
  • Quick Check: Genuine projects focus on product value, not countdown timers or pyramid‑style incentives.

5. Fake Support & Phishing Links

Impostors pose as wallet support reps, asking for seed phrases.

  • Case Study: In 2025, phishing bots on X/Twitter targeted MetaMask users, draining $5 million in a week.
  • Quick Check: Support will never request your private key. Bookmark official URLs; type them manually when in doubt.

6. Unrealistic Whitepaper & Roadmap

If the project claims “AI‑powered quantum mining” with zero technical breakdown—run.

  • Case Study: HyperVerse promised “space meta‑nodes” but delivered none of the outlined tech.
  • Quick Check: Skim for clear milestones, budget allocation, and real‑world deliverables.

Quick 30‑Second Safety Routine

  1. Google + “scam” the project name.
  2. Verify contract address on blockchain explorers.
  3. Check team LinkedIn/Twitter history (>1 year?).
  4. Scan for an audit link from a credible firm.
  5. If anything feels off—skip it.
