You sold crypto for cash. The buyer's bank transfer came from a hacked account. Now your own bank has closed you down and the police are asking questions — even though you're the one who got scammed.
How the "Triangulation" Scam Works
Peer-to-peer crypto trading — selling crypto directly to another individual for a bank transfer, outside a regulated exchange's own matching system — carries a specific and serious risk: the buyer pays you using funds from a bank account they've compromised, not their own money. You receive the transfer, hand over the crypto, and later discover the payment has been reversed or clawed back once the real account holder reports the fraud — and in the meantime, your own bank account is flagged as having received suspected fraudulent funds.
From your bank's perspective, this pattern — receiving transfers from third-party accounts unrelated to your usual banking activity, tied to crypto trading — closely resembles classic "money mule" behavior, where someone's account is used to launder stolen funds, whether or not that person knowingly participated. Banks and law enforcement can't always immediately distinguish an innocent P2P seller from a knowing participant.
Documentation That Protects You
If you trade P2P regularly, build a habit of documenting each trade as if you might need to prove your innocence later — because you might:
- A record of the crypto transfer itself — transaction hash, timestamp, wallet addresses involved.
- Communication with the buyer — the platform chat or messages agreeing to the trade terms, ideally through a platform that retains these records rather than an ephemeral chat app.
- Confirmation of the trading platform used, if any — trading through an established P2P platform with dispute resolution and identity verification is meaningfully safer than arranging trades entirely off-platform.
Responding to Your Bank's Fraud Department
If your account is flagged or frozen following a P2P trade:
- Respond promptly and in writing — delay can itself look like evasion.
- Provide your full documentation proactively rather than waiting to be asked for each piece individually.
- Be direct about the nature of the transaction — explain clearly that you were selling cryptocurrency and had no way of independently verifying the source of the buyer's payment before receiving it.
- Cooperate with any police involvement rather than treating it as adversarial — an investigation confirming you were an unwitting recipient, not a knowing participant, is the outcome you want, and cooperation supports reaching it.
What This Means for You
If you're active in P2P crypto trading, treat documentation as a default habit, not something you do only after a problem arises — by the time your account is flagged, reconstructing a clean record is much harder than having kept one from the start. Favor established P2P platforms with built-in dispute resolution over informal off-platform arrangements.
If your account is frozen, generate a formal response requesting the specific concern, and keep a dated log of every interaction with your bank's fraud team.
