How do I buy crypto and earn rewards?
Once you earn your first €5 reward in BTC, your streak will simply reset to Day 2. You'll then need to complete 4 more daily buys to get the final reward. If there aren't enough days left before March 15, 2025, but you have completed your first qualifying buy order by March 11, 2026, you'll receive €5 in BTC. Otherwise, you'll receive no reward.5. What are the important rules to remember?Published on Feb 19, 2026Updated on May 29, 20263Buy crypto with rewards terms and conditions
Reset Mechanics: Because your Base Reward (€5 BTC) is secured on Day 1, a missed day resets your progress to Day 2. You would then need 4 more successful daily buys to reach the 5-day milestone.5. Edge Cases and Participation Risks Late Enrollment Risk: March 11, 2026 is the final day to enroll. For example, if you enroll on March 11 but do not make your second buy until March 13, it is mathematically impossible to complete a 5-day streak by the March 15 deadline.Published on Feb 19, 2026Updated on May 29, 2026OKX Sub-Affiliate link rules

Buy/Sell Mode: Within the same market, users can only hold a one-sided position (Up or Down). For example, if a user already holds 5 Up contracts and buys 6 Down contracts, upon execution the system nets the positions — resulting in a final position of 1 Down contract — and releases the margin for the original 5 Up contracts.Published on Apr 16, 2026Updated on May 29, 2026Crypto profit & loss analysis (PnL) FAQ
