So sánh OKX vs KuCoin — phí & điều kiện

OKX — Regular user tier (assets < 100,000 USD and 30-day volume below the VIP 1 threshold). No token-discount applied. Spot and perpetual futures tabs of the official trading-fee page. Re-verified 2026-10-12 by weekly review in-browser (Asia IP; the CI runner gets the OKX US table and cannot confirm): Spot Standard "Regular user" 0.0800% / 0.1000%; Futures fee-table JSON behind the same page "Regular user" standardMakerFee 0.0002 / standardTakerFee 0.0005. listed_coins = 350 from the official OKX Learn wording "350+ coins" (about page only says "hundreds of tokens"). OKB fee-discount tiers could not be read from the fees page and help articles conflict on whether OKB affects tiers, so native_token_fee_discount_pct stays null.
