Crypto Investment Fraud & Ponzi Schemes

Investment fraud in crypto rarely needs a technical exploit. It needs a number that compounds faster than reality and an audience that has seen enough genuine upside to believe it.

How this vector actually works

The cases here run from classic pay-the-old-with-the-new schemes to funded projects that raised, delivered nothing and left quietly, and to payment mandates signed during what felt like routine onboarding. Different wrappers, one arithmetic.

  • The promise — A fixed daily or weekly return, described as arbitrage, market making or an AI trading engine. Volatility is never mentioned.
  • The circulation — Early withdrawals are paid from later deposits. Real yield never exists; the dashboard is a spreadsheet with a chart on it.
  • The wall — Withdrawals slow, then require a fee, a tax, an upgrade. Deposits are still instant. That asymmetry is the whole story.

Red flags you can check in a minute

Any single item below is enough to stop and verify before you sign, send or install anything. Guaranteed returns are a maths problem, and the maths always resolves the same way.

  • Any return described as guaranteed, fixed or risk-free.
  • Referral commissions that pay more than the underlying strategy plausibly could.
  • Withdrawals gated behind a payment you must fund from outside.
  • No verifiable counterparty, licence or on-chain proof of the strategy.
  • A mandate, direct debit or recurring authorisation signed during onboarding.

If it already happened

Order matters more than speed of panic: contain the wallet first, preserve the evidence second, report third. Recovery services that contact you after the fact are the follow-up scam.

  • Cancel any recurring mandate at the bank, not just in the platform's settings.
  • Do not pay the withdrawal fee — it is the scheme's last revenue line, not a route out.
  • Export the account history and all communications before access disappears.
  • Warn whoever referred you; in most schemes they are the next victim, not the operator.
