Example 1: Selling U gets bitten back by 'dirty money' (most common)
Background:
Xiao Zhang sells USDT on a trading platform (OTC), with an order of 10,000 U.
The buyer paid quickly using a bank card transfer.
Process:
Xiao Zhang confirms receipt → Releases currency
2 days later, the bank card was suddenly frozen
Bank notification: 'Suspected of receiving fraud-related funds, cooperate with police investigation'
Truth:
The buyer used the money of the fraud victim
Funding chain:
Fraud victim → Buyer's bank card → Xiao Zhang's bank card
Although Xiao Zhang is a normal transaction, he is considered a 'transitional receiver' in the funding path
Result:
Bank card frozen for 3–6 months
Need to provide materials: transaction records, chat records, platform order screenshots
U is already gone, and the money can't be used for now
Example 2: Bought U using a 'problematic card', account freeze for the whole family
Background:
Xiao Li wants to buy U and found a seller with a 'particularly attractive price'.
Process:
Transfer to buy U → Successful arrival
One week later:
Bank card frozen
WeChat / Alipay risk control restrictions
Other cards under your name have been 'warned'
Reason:
The seller's card itself is a scoring card / black card
Xiao Li's transfer was marked as 'related transaction involving a case'
Result:
Not just one card suffers
Unfreezing requires repeated explanations of 'why buy virtual currency'
Two, Why buying and selling U is easy to get frozen? (Core logic)
In summary:
Banks/police don’t care if you are innocent, they only look at whether there are issues with the funds
Key 3 points:
USDT is a high-risk keyword
Dirty money must flow to OTC
Frozen is 'the people who handled the money', not 'the bad people'
Three, Unfreezing guidelines (the key points)
✅ 1️⃣ Use a 'dedicated card' for U transactions (survival baseline)
Never use:
Salary card
Mortgage / car loan repayment card
Social security / housing fund binding card
✅ 2️⃣ Amount should not be too 'standardized'
Dangerous operation:
5000, 10000, 20000 (risk control's favorite)
Relatively safe:
4970, 9830, 19640
Split into multiple transactions, not consecutively arriving within seconds
✅ 3️⃣ Do not trade with 'perfect buyers/sellers'
High-risk characteristics:
New account
Few transaction records
Price obviously higher/lower than the market
Less talk, urgent pressure, copycat scripts
In short:
Too smooth transactions are often the most dangerous
✅ 4️⃣ Never write these words in notes
❌ Prohibited words:
USDT / U
Virtual currency / digital currency
Coin / transaction
✅ Available:
Payment for goods
Service fee
Transaction funds
(Don't be too specific)
✅ 5️⃣ Keep evidence! Keep evidence! Keep evidence!
Must save:
Platform order screenshots
Chat records
Transfer records
Counterparty nickname + UID
Once frozen, these are your 'lifesaving materials'
✅ 6️⃣ Correct response after being frozen
Never:
Randomly call the bank's customer service
Blindly admit 'speculating on currency'
Make up stories
Correct process:
Ask clearly: Bank freeze or judicial freeze
Need freeze document / freezing agency
Prepare materials
Process, don’t force it
