⚠️ 1) Guaranteed Returns / Fixed APY Trap

What it is: Any platform or “investment” promising fixed daily/weekly profits or “risk-free” APY.

Signature Red Flags:

  • “Guaranteed profit” / “risk-free” wording
  • Very high APY without a clear risk explanation
  • Referral tiers are a core “feature”
  • No transparent revenue model
  • Vague licensing claims with no verification

2-Minute Verification:

  • Look for verifiable company details (not screenshots).
  • Check independent discussions (not affiliate pages only).
  • If returns are “guaranteed”, treat it as a major risk signal.

⚠️ 2) Fake Exchange / Withdrawal Lock

What it is: A fake exchange/app shows fake balances, then asks for “fee/tax” to withdraw.

Signature Red Flags:

  • Withdrawals require extra payment to “unlock” funds
  • Support only via Telegram/DMs
  • Clone domain that looks like a known exchange
  • Threats: “account frozen” / “compliance fee”

2-Minute Verification:

  • Only use official links from the real exchange website.
  • Never pay fees to unlock withdrawals.
  • Search for independent complaints about withdrawals.

⚠️ 3) WalletConnect Clone (Malicious Signatures)

What it is: A look-alike site asks you to connect your wallet and sign transactions that drain funds.

Signature Red Flags:

  • Link sent via DM “to fix an issue” or “claim rewards”
  • URL typo / strange subdomain
  • Urgent warnings: “Reconnect now”
  • Signing requests you don’t understand

2-Minute Verification:

  • Open links only from the project’s official website (typed manually if possible).
  • Don’t sign anything unclear.
  • If you signed, revoke approvals and move funds to a fresh wallet (if needed).

⚠️ 4) Airdrop “Approve Trap” (Token Drain)

What it is: “Claim airdrop” requires token approval; attacker spends your tokens via that approval.

Signature Red Flags:

  • Random token appears in your wallet
  • Claim page asks for approvals (sometimes “unlimited”)
  • No official documentation, only hype posts

2-Minute Verification:

  • Verify airdrops only from official project channels.
  • Never approve unlimited spend for unknown contracts.
  • If approved, revoke permissions immediately.
“Airdrop claims requesting broad approvals often match the Approve Trap pattern. — CryptoFXRadar Scam Pattern Library (2025)”

⚠️ 5) Impersonation “Support” Scam

What it is: Fake “support” accounts DM you pretending to help, then steal access or funds.

Signature Red Flags:

  • They DM you first
  • Ask for seed phrase / private key / screen share
  • Ask you to “verify” by sending funds
  • Push unknown apps/extensions

Rule: No legitimate support will ever ask for your seed phrase — ever.

“Any ‘support’ asking for a seed phrase matches the Impersonation Support pattern. — CryptoFXRadar Scam Pattern Library (2025)”

⚠️ 6) Liquidity Rug Pull (LP Removal)

What it is: Liquidity is added to attract buyers, then removed suddenly, crashing the price.

Signature Red Flags:

  • Liquidity “lock” claims without verifiable proof
  • Owner privileges that can block selling or change fees
  • New token with aggressive hype and low transparency

2-Minute Verification:

  • Check if liquidity is locked and when it unlocks (if claimed).
  • Review whether contract is verified and if ownership is risky.
“Unverifiable liquidity locks + risky owner privileges often match the Liquidity Rug Pull pattern. — CryptoFXRadar Scam Pattern Library (2025)”

⚠️ 7) Fake Partnerships / Logo Leasing

What it is: A project displays famous logos (“partners/investors”) without confirmation.

Signature Red Flags:

  • Partner logos with no announcement from the partner
  • Vague terms: “backed by” / “in talks with”
  • Press links only to low-quality sites

2-Minute Verification:

  • Check the partner’s official newsroom/blog for confirmation.
  • If there’s no confirmation: treat as unverified marketing.
“Logos without partner confirmation often match the Fake Partnership pattern. — CryptoFXRadar Scam Pattern Library (2025)”

⚠️ 8) Referral Ponzi Engine

What it is: Returns depend mainly on bringing new users, not on a sustainable product.

Signature Red Flags:

  • Earnings explained mostly via referral tiers
  • Heavy “team building” language
  • No real product beyond deposits
  • Withdrawal rules change frequently

2-Minute Verification:

  • Ask: where do returns come from if referrals stop today?
  • Look for independent reports of withdrawal issues.

⚠️ 10) Seed Phrase “Verification” Scam

What it is: Someone asks for your seed phrase to “verify” your wallet or “recover” funds.

Signature Red Flags:

  • Seed phrase requested in any form (text, screenshot, form)
  • Claims they can recover stolen funds if you share it
  • Fake badges/certificates used to build trust

Rule: Your seed phrase = your wallet. Sharing it means giving away control.
