💳 Friends' Bank Cards Frozen for 72 Hours: A Lesson Learned the Hard Way:

These 3 Life-Saving Rules Are a Must-Read for Cryptocurrency Enthusiasts! It's recommended that everyone keeps a copy.

Yesterday morning, a newcomer in the group cried out in a voice message:

"Bro, I just sold some USDT and the money just arrived, and then my phone popped up a bank freeze notification. I was completely stunned..."

Don't laugh at him; you and I could easily be next.

The following practical guide to preventing card freezes is earned through blood and sweat. Knowledge = Survival.

⚠️【3 Important Rules to Remember for OTC Trading】

🔍 1. Don't Choose Platforms Randomly

Be honest and stick to "Established Exchange H" and "Top Platform B".

Platforms with T+1/T+2 fund arrival delay mechanisms are safer (even though the arrival is slow, it can save you).

🏦 2. Use a Dedicated Bank Card

Make sure to prepare a "dedicated card for receiving cryptocurrency payments" and keep it separate from your salary and living expenses cards!

Local banks are more resilient (such as XX Bank/XX Rural Commercial Bank).

Never use the big four banks; national banks respond to freezes ridiculously fast...

❌ 3. Avoid These Transaction Methods!

Frequent receiving from the same merchant? High risk! (More than 3 transactions in a day can easily trigger risk control.)

Transfer out immediately after receiving? Don't play with fire; at least wait 24 hours before moving it!

Don't touch certain "oil-like stablecoins"! Trading major cryptocurrencies is relatively safer.

🎯【Advanced Card Protection Techniques】

Try to trade between 9:00 AM and 9:00 PM on weekdays; avoid late-night risky routes.

After funds are released, try to withdraw cash using an ATM or spend it in physical stores.

Limit trading to a maximum of 3 times a month; larger single transactions are actually safer (transactions over 50,000 are much steadier).

🧨 Real Failure Cases (More Insightful After Reading)

A friend used his salary card to receive several USDT payments, and once it got frozen, all bank accounts online were blocked.

Someone tried to take shortcuts with small transactions for three consecutive days and ended up being flagged by the risk control system as "suspected money laundering"; once locked, the card was out for half a year.

Beware of so-called "Blue Shield Merchants"; there's a guy who found that the merchant had less than 100 transactions in a month...

✅ A final reminder:

The cryptocurrency world has no textbooks, only the painful costs of predecessors.

In trading, if you can be steady, don't rush; if you can play dead, don't make waves.

Protect your card first, earn money second!
