Frequently Asked Questions (FAQ)
Q1: What is T+N buy protection on OKX?
A: T+N refers to a temporary lock period (1–7 days) where newly bought assets may be restricted from withdrawal or resale. This security feature helps prevent fraud and is triggered based on risk assessment algorithms.
Q2: Why can’t I sell my USDT even though I have balance?
A: Common reasons include:
- Assets are in a financial account (not fund account)—transfer them first.
- Recent purchases are under T+N lock.
- Pending blockchain confirmations after deposit.
- Existing orders freezing available balance.
Q3: Can I use someone else’s bank account to pay?
A: No. All payment methods must be registered under your verified identity. Mismatched names may lead to fund freezes or account suspension.
Q4: How do I verify the buyer’s real name during a sale?
A: Log into your payment app (e.g., WeChat). If not friends, you might only see partial names or nicknames. Request a screen recording of the buyer’s full name during payment for verification.
Q5: What happens if I cancel too many orders?
A: Excessive cancellations or missed payments within time limits can harm your trading reputation, potentially blocking further trades for the day.
Q6: Is there a fee for buying USDT on C2C?
A: Most peer-to-peer trades on OKX are zero-fee for buyers. However, spreads between sellers’ prices act as an implicit cost—always compare offers before choosing.
