P2P Triangle Scams and Fake Payment Proof in Vietnam – How to Spot Them

Updated 3 Oct 20264 min read

Legal notice: since 1 September 2026, under Decree 284/2026/ND-CP, individuals in Vietnam who trade crypto-assets other than through a provider licensed by the Ministry of Finance can be fined 30–50 million dong. Binance, OKX and Bybit are not licensed in Vietnam. coinglee provides price information for reference only.

Two scams cause most losses for people who sell USDT on P2P in Vietnam: the triangle scam, where the money you receive really comes from a third victim, and fake payment proof, where no money arrives at all. Both work only because the seller releases USDT too early. This guide explains each one and the checks that stop them.

Selling today? The current best selling price is in the “You sell USDT” column of the USDT rate board.

How a triangle scam works

  1. The scammer opens a P2P order to buy your USDT.
  2. At the same time they post a fake offer somewhere else: a cheap phone on Facebook, a room deposit, an online “task” job. A real person, the victim, agrees to pay.
  3. The scammer gives the victim your bank account as the payment account.
  4. The victim transfers dong to you. You see real money arrive, with a sensible amount, and release the USDT.
  5. The scammer disappears with the USDT. The victim never gets the phone, reports the transfer to the police and the bank, and the trail leads to your account.

You did nothing illegal on purpose, but the money in your account came from a fraud victim. Your account can be frozen, you may be asked to return the money, and you’ve already lost the USDT.

The one check that stops it

The name on the transfer must match the buyer’s verified name in the order.

  • Open your own banking app and look at the sender’s name on the credit.
  • Compare it with the buyer’s KYC name shown in the P2P order.
  • Different name? Don’t release. Not even if the buyer says it’s “my wife’s account” or “my company’s account”.

Other warning signs:

  • The transfer note mentions something unrelated: “phone deposit”, “room”, “order #…”.
  • The amount is paid in several parts from different people.
  • The buyer is new, has few orders, or pushes you to hurry.
  • The buyer asks you to continue on Zalo or Telegram.

Fake payment proof

The second scam is simpler: the buyer marks the order as paid and sends “proof”, but no money arrived. Common forms:

  • Edited screenshots of a banking app showing a successful transfer.
  • Fake SMS that look like balance alerts from your bank.
  • Fake emails pretending to be from the bank or the exchange (“payment confirmed, release now”).
  • “Pending” transfers: “the bank is processing, it will arrive in 30 minutes, release first”.

The rule is the same every time: only your own banking app counts. Check the real balance and the transaction history. If the money isn’t there, it hasn’t been paid, whatever the buyer sends you. If they keep pressuring you, open an appeal in the order and let the exchange handle it.

If you’ve received money from the wrong person

  1. Don’t release the USDT.
  2. Appeal in the P2P order with the sender name, statement and payment reference; notify your bank of any dispute or hold.
  3. Obtain official bank and exchange instructions before any refund. Never use a replacement account supplied in chat; retain any approved refund receipt.
  4. Keep everything: order number, screenshots of the order chat, the bank statement.

If you already released

  1. Report it to the exchange’s support immediately with the order number.
  2. Tell your bank what happened, especially if the victim’s bank or the police contact you.
  3. If the police get in touch, cooperate and bring the full order history. It shows you sold USDT and didn’t take part in the fraud.

Checklist before every release

  • The money is in your banking app, not just in a screenshot.
  • The amount matches exactly.
  • The sender’s name matches the buyer’s verified name.
  • One payment from one account.
  • No unrelated transfer note, no pressure, no moving to Zalo or Telegram.

More on the overall risks: trading USDT P2P safely.

Keep an order-by-order evidence file

Save the order number, the buyer’s verified name, the incoming payment reference, time and amount, plus the original chat. A screenshot sent by the buyer belongs in that file as a claim, not as proof that your bank received money. If the bank does not show the sender’s full name, request clarification rather than assuming the payment matches.

If there is already a bank hold or a fraud complaint, tell the bank before moving the disputed balance. A private agreement with the P2P buyer cannot close someone else’s bank complaint. When seeking help, use official bank and exchange channels; avoid posting full account numbers, passports or statements in public groups.
