2. Once you have 10 referrals who've claimed $10 rewards for buying crypto, you can become an OKEx affiliate and start earning % of your invitees' trading fees. In that case, you're no longer eligible to receive the referral rewards.
For the first 10 referrals, you both receive $10 after the invitees successfully purchased crypto but it's limited to 10 referrals.
