What Is USDT and Why Should You Buy It?
USDT (Tether) is a stablecoin pegged 1:1 to the U.S. dollar. Unlike volatile cryptocurrencies like Bitcoin, USDT maintains price stability, making it ideal for:
- Preserving value during market downturns
- Facilitating fast cross-border transactions
- Serving as a bridge currency when trading altcoins
Many users in China prefer buying USDT first before converting it into other cryptocurrencies like BTC or ETH.
How to Buy USDT on OKX:
- Deposit CNY via P2P as described earlier
- Go to the Trade section
- Find the USDT/CNY pair
- Place a market or limit order based on your preference
You can then hold USDT, trade it, or transfer it to other wallets or exchanges.
Ensuring Fund Security: Best Practices
While platforms like OKX implement advanced security measures, user behavior plays a crucial role in protecting assets.
Top Security Tips:
- Enable Two-Factor Authentication (2FA) using Google Authenticator (not SMS)
- Never share your recovery phrase or password
- Use a dedicated email address for crypto accounts
- Regularly monitor login activity
- Withdraw large holdings to a hardware wallet
⚠️ Avoid "frequent card freezing" (冻卡) by using personal funds only and avoiding high-risk transactions with unfamiliar counterparties.
