Okx is restricting account logins, claiming it's for compliance, but in reality, it's a cost-cutting measure due to a sharp drop in trading volume and significantly reduced platform revenue. To put it simply, over 50% of customers in the Chinese-speaking region opened secondary accounts using relatives' and friends' accounts for rebates. Now, face verification is required to log in, which means a large number of rebate accounts can no longer log in to trade and can only use their own accounts to trade. This allows the platform to reduce more than 40% of fee-sharing.
