1. Abnormal Trading Activity Detected
Possible Reasons:
•Frequent large deposits/withdrawals causing irregular fund movements
•High volume of small transactions within a short time (may be flagged as money laundering)
•Use of high-risk IP addresses (e.g., sanctioned countries)
Solution:
•Contact exchange customer support and provide identity verification along with an explanation of your transactions
•Provide proof of funds (e.g., deposit records, transaction screenshots)
2. Transactions Involving Illegal Activities
Possible Reasons:
• Account linked to fraud, hacking, or financial scams
•Exchange received a request for investigation from law enforcement agencies (e.g., FBI, Interpol)
•Funds originate from illicit activities (e.g., black market transactions, darknet trades, illegal gambling)
Solution:
• Verify if the freeze was a mistake and submit an appeal
•Provide proof of legal fund sources (e.g., bank statements, transaction history)
• If under legal investigation, you may need to wait until authorities conclude their inquiry
3. Exchange Policy Changes
Possible Reasons:
• Exchange temporarily suspending certain token trades or withdrawals
•Account restrictions due to policy updates affecting users from specific countries/regions
•Ongoing system maintenance causing temporary asset inaccessibility
Solution:
•Check exchange announcements to see if it’s a system upgrade issue
•Contact exchange support to confirm if your account is affected by policy changes
• If the exchange no longer supports your region, consider transferring assets to a supported platform
4. Risk Control Measures or False Flagging
Possible Reasons:
• Automated risk control systems flagged unusual transactions
•Assets linked to high-risk wallet addresses (e.g., interacted with a hacker’s wallet)
• Withdrawals sent to a wallet marked as suspicious by the exchange
If your assets are frozen, contact the exchange immediately and provide all necessary documentation to resolve the issue.
