FAQ.
01What is the OKX invite code?
Our code is OK66688. Enter it in the “Referral code (optional)” field when you sign up, or use our sign-up button and it is filled in automatically. It can only be added at sign-up.
02What does the code give me?
Accounts opened with OK66688 get 20% off trading fees for life on every coin, spot and futures. The exact rate is whatever OKX shows on its fee page.
03What coins can I buy on OKX?
OKX lists hundreds of spot pairs, including bitcoin, Ethereum, Solana, XRP, Dogecoin and many trending tokens. Search the coin under Trade → Spot to check.
04What’s the minimum I can buy?
Almost every coin can be bought in fractions, so a few dollars is enough. The trade page shows the exact minimum.
05Limit or market order?
Market orders fill instantly but can slip in fast markets. Limit orders fill at your price and pay the cheaper maker fee. Beginners should use limit orders near the current price.

No. Most coins trade directly against USDT, so buy them with USDT and skip an extra fee.
07Where should I keep my coins?
For short-term trading, your OKX account with an authenticator app and withdrawal whitelist is fine. For larger long-term holdings, consider a wallet you control, and pick the right network when withdrawing.
08Is OKX available in my country?
OKX does not serve every country or region. Check the OKX user agreement and local law. We do not provide ways to get around regional restrictions.
