OKX vs MEXC — taxas e condições

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. [Withdrawal fees checked 2026-10-28 via the official Crypto withdrawal fee page, read in-browser (the public REST endpoint needs an API key): BTC 0.000015 BTC on Bitcoin; USDT 1.5 USDT on Tron (TRC20) (cheapest: Plasma (USDT0) 0.0000049). The exchange adjusts them with network conditions.]

MEXC — Base rates from the official MEXC fee guide (published 2026-07-27): spot 0%/0.05%, futures 0%/0.02% (maker/taker). MEXC explicitly states fees vary by country, region and trading pair, and runs frequent per-pair promotions — the live fee page renders different values per load. No MX-token discount applied. native_token_fee_discount_pct = 20% standard MX deduction (50% when holding >500 MX, not applied here). futures_max_leverage = 500x on BTCUSDT/ETHUSDT (announced 2025-04-23). listed_coins from official press boilerplate 'over 3,000 digital assets'. Withdrawal fees are dynamic (network-condition based); the value recorded is the figure shown on the official fee page at check time. Re-verified 2026-10-19 by weekly review in-browser: official fee guide (updated 2026-10-18) "Spot maker orders cost 0% on every MEXC pair, while the standard taker fee is 0.05%" and "BTCUSDT perpetual futures cost 0% maker and 0.02% taker". Unchanged. [Withdrawal fees checked 2026-10-28 via public API: BTC 0.00002 BTC on Bitcoin(BTC) (cheapest: BNB Smart Chain(BEP20) 2.5e-7); USDT 0.5 USDT on Tron(TRC20) (cheapest: PLASMA 0).
