OKX DEX starts charging fees, and opinions on the fee structure vary across groups. But no matter what, let's grab the fee discount first. I've already set up a 20% reduction, currently the highest, and it only takes 1 minute to set up. 1. Open settings, make sure OKX is updated to the latest version. 2. Click on the invitation plan. 3. Click and enter the invitation code BILILI. Group members' feedback: Based on address interaction, OKX has prohibited large accounts from inviting small accounts.
