So sánh Deribit vs OKX — phí & điều kiện

Deribit — Standard tier (no VIP criteria) from the official Fees support article, converted from basis points: perpetuals & futures 1.5/3.5 bps = 0.015%/0.035%; spot 2/5 bps = 0.02%/0.05%. Options fees (3/3 bps with a 12.5% premium cap) are not represented in this schema. Derivatives-focused exchange, now part of Coinbase. Crypto withdrawal fees are not fixed on the official Fees article (on-chain network fee applies); the public get_currencies endpoint exposes the current per-currency withdrawal_fee, recorded below. USDT is withdrawable on Ethereum only (no TRC20 route). Insurance fund: "approximately $140 million" at year-end 2024 per official Insights update. live_chat_support = true via 24/7 live support staff in public Telegram chat rooms (EN/ZH/RU) per the official Contact Us article (403 — via search excerpt); not an in-app widget. proof_of_reserves: daily PoR page discontinued 2026-09-01, but the same notice states independent PoR audits continue twice a year, so recorded true. [Withdrawal fees checked 2026-10-28 via public API: BTC 0.00001 BTC on BTC; USDT 2 USDT on Ethereum (no TRC20 route listed). The exchange adjusts them with network conditions.]

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.]
