OKX Review

Security and licensing

OKX is operated globally by Aux Cayes Fintech Co. Ltd., a Seychelles-incorporated entity, alongside a growing list of regional licenses. In the EU it holds a full MiCA crypto-asset service provider (CASP) license through OKX Europe Limited, granted by Malta's MFSA in January 2025, well ahead of the July 2026 deadline for unlicensed exchanges to exit the bloc. It also holds a derivatives license from Dubai's VARA and is registered with AUSTRAC in Australia.

The exchange's regulatory history includes a serious blemish: in February 2025, OKX pled guilty in US federal court to operating an unlicensed money-transmitting business, admitting it let US customers trade for years — including via VPNs — despite a policy barring them. It agreed to pay just over $504 million in fines and forfeiture and accepted a three-year compliance monitor running through 2027. OKX has since relaunched a separate, more restricted OKX US platform under the new terms.

Trading fees

OKX's base-tier (Level 1) spot fees are 0.08% maker and 0.10% taker, which undercuts many other large exchanges on the maker side. Perpetual futures and other derivatives run cheaper still at the base tier — roughly 0.02% maker and 0.05% taker — with rates falling further as 30-day trading volume or OKB token holdings increase across OKX's VIP tiers.

Deposits are free. Withdrawal fees are asset- and network-specific rather than a flat percentage — for example, a Bitcoin withdrawal or a stablecoin withdrawal on a cheaper network costs a small fixed amount set by network conditions, and OKX periodically adjusts these amounts. Holding and paying with OKB, OKX's native exchange token, unlocks fee discounts on top of volume-based tiers.

Coins and products

Coin counts vary by how you count them: OKX's core spot exchange lists in the region of 300+ tradable coins and several hundred trading pairs, while marketing materials citing 'thousands' of assets are generally counting tokens reachable through its DEX aggregator and Web3 wallet rather than the centralized exchange order book. Beyond spot, OKX offers futures, perpetual swaps, options, margin trading, and a Convert tool for simple swaps.

OKB is OKX's native token, used for trading fee discounts, VIP tier perks, and as the gas token on OKX's own Ethereum layer-2 network, X Layer. OKX also runs an active staking and earn section, and supports copy trading for users who want to follow other traders' positions.

Proof of reserves and fund safety

OKX has published dozens of consecutive monthly proof-of-reserves reports, one of the longer unbroken track records among major exchanges. Recent reports have shown reserve ratios comfortably above 100% for major assets like BTC, ETH, USDT, and USDC, with OKX stating that the large majority of user assets are held in offline cold storage.

Derivatives trading is backstopped by mark-price liquidation and an insurance fund with auto-deleveraging as a last resort; specific insurance fund size figures are not consistently published, so exact numbers should be checked on OKX's own risk pages before relying on them. OKX's public security record shows no large-scale exchange hack of user funds, though it has disclosed smaller incidents — including a 2024 case where a small number of accounts were compromised via forged identity documents, with affected users compensated.

Deposits and withdrawals

Funding options depend on region but generally include direct crypto deposits, bank transfer, card purchases, and P2P trading where users buy crypto from other users using local payment methods — useful in regions with limited direct banking rails. Fiat support varies significantly by country and is more limited for OKX US than for the global platform.

Withdrawals require completed identity verification and are subject to OKX's own risk controls, which several Trustpilot reviewers describe as a source of delays — accounts placed under review, extra document requests, or, in a minority of disputed cases, extended holds. This is worth weighing against OKX's compliance overhaul following its 2025 US settlement, which has tightened these controls further.

Support

OKX offers 24/7 live chat and a ticket-based help center covering account, deposit, and withdrawal issues, with OKX stating typical ticket responses within roughly 24 hours. Phone support is limited: outside of a California-specific line, most regions only get a voicemail callback option rather than direct phone support.

Trustpilot sentiment is sharply split — a large share of reviews are five-star, but a large share are also one-star, concentrated on withdrawal delays and frozen-account complaints, versus much stronger average ratings on the Apple App Store and Google Play. Treat any single review source with some caution and expect variable resolution times for account-specific disputes.

Who is it for

OKX suits active and intermediate-to-advanced traders who want low base fees, deep derivatives markets, and native access to Web3/DeFi without leaving the app. Its VIP and OKB fee-discount structure rewards higher-volume traders, and its long proof-of-reserves history appeals to users who weigh custodial risk carefully.

It's a weaker fit for complete beginners who want the simplest possible interface, for anyone in the United States wanting the full global product suite, and for risk-averse users who want zero regulatory history to research — the 2025 US settlement is a legitimate factor to weigh, even though it resulted in a formal resolution and an ongoing compliance overhaul rather than an ongoing legal problem.
