It is a points-based promotional campaign where participants earn campaign points by completing tasks and use these points to participate in matches and submit picks on match outcomes. Participation is free of charge subject to the eligibility requirements herein and the points accumulated over the Campaign Period (as defined below) determine each participant's eligibility for, and share of, the Campaign rewards. Points are not currency, cannot be withdrawn, and have no value outside of this promotional campaign. For selected matches, OKX may, at its sole discretion, activate supplementary match-linked rewards ("Match Linked Rewards"). Match-Linked Rewards are not guaranteed, but once it is activated, Clause 7 of these Terms shall apply.

3. Campaign Key Dates

Key dates of the Campaign are as follows:

4. Eligibility

4.1 Users, who are not employees of OKX, must complete KYC identity verification to participate and receive the rewards in this Campaign. KYB accounts are not eligible.

4.2 Users from the following countries or regions (subject to verification information) may not be eligible to participate in this Campaign: please refer to clause 3 of OKX's risk and compliance disclosure.

4.3 To enroll in the Campaign, users must log in to their OKX account, visit the Campaign landing page, and click the "Get Started" button. The button must change to "Enrolled" for participation to be valid. Participation without completing this enrolment step will be void.

4.4 A user who participates in Match-Linked Rewards (if any) without prior Campaign enrolment will be automatically enrolled upon placing their first entry in that match, and will be subject to these Terms in full from the time of automatic enrolment.

5. How to gain xp?

5.1 Final xp balances at the xp Snapshot determine reward eligibility and reward amount. OKX reserves the right to adjust xp values and task parameters at any time during the Campaign Period. Where practicable, OKX will endeavour to provide advance notice of material changes.

5.2 Any unused xp balance remaining in a user's account as of the Campaign End Date will expire automatically after the Campaign ends without value. Expired xp will not be compensated, carried forward, or converted into any other form of value.

5.3 Welcome Airdrop. A one-time Welcome Airdrop is credited automatically to each user upon Campaign enrolment. The amount of the Welcome Airdrop is determined by the user's AUM level and VIP level (if applicable) at the time of the snapshot, taken at 00:00 (UTC+8) on 2 June 2026.

5.4 New User Airdrop. Eligible new users who have not previously completed a first-time deposit (FTD) and who complete the new user tasks as specified on the Campaign landing page during the Campaign Period will receive New User Airdrop. New user tasks include making cumulative deposits of at least 100 USD equivalent (via fiat or crypto). No trading activity is required. Completion of the new user tasks also constitutes the qualifying condition for the Friend Referral Reward (as defined below).

5.5 Daily Check-In. Users may check in once per calendar day (UTC+8) during the Campaign Period and receive a daily points value. Starting from Day 4 of a consecutive check-in streak, the daily points awarded are doubled (×2). Missing any calendar day breaks the streak; the counter resets to zero and standard (non-doubled) points resume. Daily check-in is independent of any other Campaign activity. No other action is required to earn daily check-in xp.

5.6 Milestone Rewards. The Campaign Period is divided into Periods of approximately ten (10) days each. Each Period independently resets the per-user match count and re-opens all milestone tiers. The Campaign comprises the following Periods:

The following milestone xp are awarded per Period. Each tier may be claimed once per Period and resets at the start of each new Period. Each match is counted once regardless of the number of picks chosen for the same match.

5.7 Friend Referral Reward. Users can earn certain xp per successful referral, capped at 20 successful referrals per user. The referrer must use their personal referral link from the Campaign landing page for credit to be attributed. Referrals flagged by OKX's risk controls do not count toward the referrer's quota and generate no reward for the referrer. A successful referral requires all three of the following conditions to be met:(i) The referred person is a new registrant to OKX who registered via the referral link shared by the referrer on the Campaign landing page;(ii) The referred person joins the Campaign; and(iii) The referred person completes the applicable new user task as specified in the Campaign landing page.

5.8 Discretionary Airdrops. OKX may, at its sole discretion, issue additional xp airdrops to selected eligible users at any time during the Campaign Period. Such discretionary airdrops are not guaranteed, are subject to any conditions OKX may determine at the time of issuance, and do not create any entitlement for any user to receive the same or a similar airdrop.

6. Campaign Total Rewards

6.1 The Total Rewards value is fixed at launch and shall be announced on the Campaign landing page.

6.2 Reward Distribution. The Total Rewards will be distributed among all Eligible Users proportionally to each user's share of the total eligible XP balance as per Clause 8. The distribution formula is: User Reward = MIN( Total Rewards x (User XP / Total Eligible XP) , Total Rewards x [Per-User Cap %] ).For the avoidance of doubt, "Total Eligible XP" includes only XP held by users who satisfy all eligibility conditions at XP Snapshot, ineligible users are excluded from the calculation. A per-user cap applies to limit the maximum share any single user may receive, and the applicable cap will be published on the Campaign landing page. Any surplus above the per-user cap shall be returned to OKX and will not be redistributed to other participants of the Campaign. OKX may require identity verification prior to any reward distribution.

6.3 Rewards are denominated in BTC. The Total Rewards amount and the applicable per-user cap will be published on the Campaign landing page.

6.4 Reward Eligibility Conditions. To appear on the Campaign leaderboard and qualify for a reward, a user must simultaneously satisfy all of the following conditions at the XP Snapshot: (i) a minimum number of qualifying matches placed during the Campaign Period; and (ii) a minimum XP balance. The applicable thresholds for each condition will be published on the Campaign landing page. For the avoidance of doubt, users who do not satisfy all conditions are excluded from the Campaign leaderboard and receive no reward. Excluded users' share of the Total Rewards will not be redistributed to other participants.

7. Match-Linked Rewards

7.1 In addition to the Campaign Total Rewards as described in Clause 6, OKX may, at its sole discretion, activate supplementary Match-Linked Rewards for specific matches during the Campaign Period. Match-Linked Rewards are not guaranteed. If activated, the rules in this Clause 7 shall apply.

Match standings are separate from and do not affect the main Campaign leaderboard. Please refer to the Campaign landing page for the confirmed Match-Linked Rewards schedule, including applicable matches, dates, and reward amounts. The schedule is subject to change at OKX's sole discretion.

7.5 Enrolment and Eligibility. Eligible users already enrolled in the Campaign are automatically eligible for any Match-Linked Rewards in which they participate. No separate registration is required. A user who has not enrolled in the Campaign and who participates in a Match-Linked Rewards will be automatically enrolled in the Campaign upon placing their first entry in that match.

8. Reward Distribution

8.1 Campaign rewards will be distributed within T+7 of final Campaign match settlement. Match-Linked Rewards will be distributed by T+2 after each match's settlement. OKX has the right to postpone the issuance of rewards for any reason it deems necessary in its sole discretion.

8.3 OKX has the discretion to convert any rewards into platform vouchers or USDT of equivalent or lesser value where platform restrictions in certain jurisdictions cause participants to be ineligible for certain rewards, where OKX is unable to procure prizes for participants, or in any other case OKX deems necessary. Where a conversion occurs, it will be made at the prevailing OKX exchange price at the time of distribution.

8.4 The value of BTC rewards may fluctuate between the xp Snapshot date and actual distribution due to market movements. OKX is not responsible for any resulting change in value.

OKX may also require further verification before processing any reward.
