Rebate comparison (this is the gap)
Fees are nearly identical, but rebate differs. Say you generate 400 USDT of perp fees this month:
- Binance (up to 40%): up to 160 USDT back.
- OKX (public 20%): 80 USDT back; for the extra beyond 20%, contact support.
After binding, Binance is clearly above the default 20%; OKX can only publish 20% per policy, so if you value OKX's ecosystem, the extra is available privately via support. For why rebate can exceed 20%, see this article.
Which should you pick?
- Choose Binance: highest rebate (40%), the largest volume and deepest liquidity, and the widest coin and product range.
- Choose OKX: you prefer OKX's perp and Web3 wallet ecosystem; official rebate is 20%, extra via support.
