How to Sell Crypto Without Getting Your Account Frozen
Account freezes can happen due to suspicious activity or policy violations. To sell USDT safely on OKX or any exchange, follow these best practices:
1. Complete KYC Verification
Fully verified accounts face fewer restrictions. Submit accurate ID documents during registration.
2. Use Legitimate Fund Sources
Ensure all deposited funds come from legal sources. Suspicious inflows may trigger automated flags.

Repeated small transactions or rapid large-volume trades may be flagged as structuring or wash trading.

Review OKX’s user agreement regularly. Violations—even unintentional ones—can lead to temporary holds.
