Bank Account Frozen After Selling USDT in Vietnam: Why It Happens and What to Do

Updated 3 Oct 20264 min read

When you sell USDT on P2P, the biggest risk isn’t losing the USDT. It’s having the bank account that received the money frozen. It happens to experienced traders too, and it can take weeks to resolve. This guide explains why it happens, the two kinds of freezes, how to lower the risk, and exactly what to do if it happens to you.

Why accounts get frozen

Almost every case starts with money that came from a scam:

  1. A scammer opens an order to buy your USDT on the exchange.
  2. At the same time, they trick someone else, with a fake online sale, a fake loan or someone posing as an official, into sending money straight to your account.
  3. You see the money and release the USDT. The scammer withdraws it.
  4. The victim reports it to the police, and the receiving account, yours, is frozen during the investigation.

You didn’t intend to do anything wrong, but your account sits in the money trail. Buyers face this much less, because they send money rather than receive it.

Two different things: a freeze and a lock

Freeze (“phong tỏa”) Temporary lock (“tạm khóa”)
Who starts it Police or another competent authority, through your bank Your bank’s own monitoring
Why A complaint links money in your account to a crime Unusual activity, e.g. many incoming payments from strangers, or missing biometric data
What’s blocked Sometimes only the disputed amount, sometimes the whole account Usually online transactions
How it ends When the authority lifts it, often after the case is handled After you verify your identity or explain the transactions at the branch

Knowing which one you have tells you who to talk to. Ask your bank directly.

Checks before you release USDT

  • The sender’s name must match the buyer’s verified name in the order. This is the most important rule. If the name differs, even slightly, don’t release.
  • The amount must match the order exactly. Several partial payments, odd amounts or strange transfer notes are reasons to stop.
  • Trust only the balance in your own banking app, never screenshots or messages.
  • Be careful with new buyers: few orders, a new account and a large first order.
  • Since 1 July 2024, under State Bank Decision 2345/QĐ-NHNN, online transfers above 10 million dong, or above 20 million dong in a day, require biometric authentication. Paying from your own account is normal now, so “it’s my wife’s/company’s account” is a red flag.

If money arrives from the wrong name: don’t release, open an appeal in the order, return the money to the account it came from as the exchange instructs, and keep all the evidence. More detail: triangle scams and fake payment proof.

Limit the damage before it happens

  • Use a separate bank account for P2P, apart from your salary and everyday account, so a freeze doesn’t stop your daily life.
  • Keep a record of each trade: order ID, time, amount, the buyer’s verified name and the in-order chat. The exchange keeps this too, but your own copy is faster.
  • Don’t let large balances sit in the P2P account.
  • Trade with buyers who have a good history. A slightly better price isn’t worth the risk.

If your account is already frozen: step by step

  1. Find out exactly what happened. Call the hotline on your card or go to a branch. Ask whether it’s a freeze or a lock, how much is blocked, the date, and which authority requested it (the police unit and case number if possible).
  2. Gather your evidence:
    • the exchange order history for the trade (order ID, time, amount, price);
    • the buyer’s verified name as shown in the order;
    • the in-order chat;
    • your bank statement showing the incoming payment and, if any, your refund. The exchange’s support team can confirm your trade history if the police ask.
  3. Contact the police unit handling the case and explain that you received the money as payment in a USDT sale. Bring printed evidence and your ID. In most cases the victim’s money has to be returned. Ask what will happen to the rest of your balance.
  4. Write a short explanation with dates, amounts, order IDs and the buyer’s name, and keep a copy of everything you hand over.
  5. Follow up regularly. Freezes linked to an investigation can take weeks or longer.

Don’t

  • Don’t pay an “unfreezing service”. Anyone online promising to unfreeze accounts quickly is almost certainly running a second scam.
  • Don’t move other money into the frozen account.
  • Don’t delete chats or order history. They’re your evidence.

Common questions

Will I get the money back? Money proven to come from a victim usually goes back to the victim. The rest of your balance is normally released when the case allows. Your USDT, already released, can’t be recovered from the exchange.

Can I keep trading in the meantime? You can’t use the frozen account. Many people stop P2P until it’s resolved, since another complaint would make things worse.

Does it affect other banks? A freeze applies to the named account, but investigators can ask other banks for information about you.

Legal note

Since 1 September 2026, under Decree 284/2026/ND-CP, trading crypto-assets other than through a licensed provider can be fined 30–50 million dong. Be aware of that when you explain the transaction. This is general information, not legal advice; for large amounts, talk to a lawyer. See also how to trade P2P safely and how to sell USDT for VND.
