12 / QUESTIONSWelcome bonus
Welcome bonus
questions.
01What is the OKX sign up bonus?
It has three parts: the new user mystery box and task rewards in the Rewards Hub, time-limited promotions such as Earn boosts, and a lifetime 20% trading fee discount when you sign up via the invite link or with code OK66688. Current campaigns are shown in the Rewards Hub.
02How much free crypto do I get for signing up?
Signing up alone does not pay out. Rewards are unlocked by tasks such as identity verification, a first deposit and a first trade. Most people receive small amounts of USDT, BTC or fee vouchers. Be wary of anyone promising thousands.
03Is the “up to 60,000 USDT” mystery box real?
“Up to” refers to the top prize tier, which very few people win. Most boxes contain small crypto amounts or vouchers. Open it in the Rewards Hub after completing the required tasks.
04Invite code or invite link, what's the difference?
None. The link okx.com/join/OK66688 fills in code OK66688 on the sign-up page. Signing up manually, type OK66688 into the referral code field. The result is identical.
05Does using an invite link affect the mystery box?
No. The link only links a referral to your account for the fee discount. You still get the mystery box and new user tasks.
06Can I add the code after signing up?
Usually not. The code can only be added at sign-up. One person can verify only one account.
07Can I withdraw trial funds?
Trial funds can only be used in specific products and the principal can't be withdrawn. Profits made under the rules may be credited. Check the voucher terms and expiry.
08Is it safe to keep USDT in Simple Earn?
Simple Earn accrues hourly and can be redeemed any time, but it is not a bank deposit. Platform risk and falling rates are real, so only use spare funds and turn on account security.
09OKX won't load or I can't log in. What now?
Check the URL is okx.com, not a mirror site. Clear cache, update the app and switch networks. If it still fails, use live chat in the app. We never provide ways to bypass network or regional restrictions.
10Is OKX available in my country?
OKX does not serve some countries and regions, and some products such as tokenized stocks have their own restrictions. Check the OKX Terms of Service and your local laws before signing up.
11Is OKX safe?
OKX publishes regular proof of reserves and keeps most assets in cold storage. No centralized platform is risk-free: use a passkey or authenticator app, set an anti-phishing code and consider self-custody for long-term holdings.
12Is this the official OKX website?
No. This is an independent affiliate guide. We don't offer logins, deposits or custody. All sign-ups and trades happen on OKX. We may earn a commission at no extra cost to you.
