You searched through countless U merchant advertisements and ultimately chose a U merchant that looked pretty good for the transaction.

U merchants transferred money to your account via Alipay, WeChat, or bank card. You confirmed the transaction was completed, and 1 million USDT arrived in the U merchant's account.

In this process, the exchange acts as a guarantor, temporarily locking your USDT. Once the merchant completes the payment, you confirm the information, and the exchange releases the funds. There should be no issues throughout this process; the only potential problem is...

The 1 million the merchant gave you has dark money!

This is an inevitable link in your withdrawal process; how can you confirm that the merchant's funds are secure?

Days of accumulation? Promises of frozen card compensation? The reputation of old cryptocurrency merchants?

Which one...?

You tell me this is useful?

It's useless; countless cases of frozen cards tell everyone that this freezing of cards is a low-budget 'black swan' event. When funds will blow up completely depends on when the victim reports the case. I have a friend whose frozen card case lasted the longest at two years before being frozen!

Make it clear, it was frozen two years later!

He was confused himself; when he prepared to find the transaction order to appeal, the exchange had already ceased operations, making it impossible to find any information!

The fundamental reason for frozen cards is:

1. You don’t know whether the money transferred by U merchants has issues.

2. Even if there are no issues this time, funds involved in previous cases can be frozen retroactively months later.

3. Even if there are no problems at all, the other party may be flagged by the bank's big data risk control due to frequent deposits and withdrawals, leading to the freezing of cards related to such transactions.

4. Lastly, if your domestic card frequently has funds going in and out, inconsistent with your past identity; quick deposits and withdrawals, with no time left for storage, will also trigger the bank's risk control freeze.

Hehe, it is indeed possible to investigate, but this falls under on-chain technology which I won't discuss right now. This isn't about the uncle checking the deposit and withdrawal information but rather about your bank card being monitored by the anti-fraud big data center...

The logic is like this: gambling brothers often use USDT for transactions and then buy and sell coins on various exchange platforms. Due to the high frequency of transactions, their bank cards and those flagged by the anti-fraud center have had interactions, which were monitored by big data.

Most cryptocurrency merchants' bank cards are high-risk cards. If you have dealings with them over time, your bank card will also be labeled as 'fraud' in big data.

Do you understand?
