From Selling U to the Secure Full Process of Bank Card
Last night, someone fell for it again!
At 1 AM, a group friend sold U:
3 minutes after arrival: Bank card suspended for non-counter transactions
Bank response: Triggered anti-money laundering risk control, need to explain the source of funds in person
Key mistake: Using salary card + late-night transaction + instant fund transfer
Fourfold Protection System (OTC veterans keep it secret)
1. Platform Selection
Only recognize the three major exchanges: Binance/OKX/Kraken (small platforms have a freezing rate over 60%)
Enable T+1 arrival: Although it takes 1 day longer, the freezing probability decreases by 80%
Taboo:
Use 'instant arrival' channels
Believe in 'special exchange rate' merchants
2. Bank Card Rules
Card Type Freezing Probability Recommendation Index
Big Four Banks 45% ★★☆☆☆
City Commercial Bank 18% ★★★★☆
Agricultural Commercial Bank 12% ★★★★★
Salary Card 67% Not Recommended
3. Operational Precautions
1. Merchant Rotation System: No more than 3 times per week with the same merchant (avoid related transactions)
2. Fund Residue: Arrived funds should be kept for ≥24 hours
3. Time Control: Operations between 09:00-21:00 (avoid system sensitive periods)
4. Currency Selection: BTC > ETH > USDT (Bank recognition friendliness ranking)
4. Advanced Concealment Techniques
Cash Closure: ATM withdrawal > Counter transfer > Mobile banking transfer
Consumption Laundering: Directly swipe card for consumption (jewelry/luxury goods store is best)
Amount Magic: Single withdrawal of 88,000 > 100,000 (avoid large amount reporting)
