What is OKX?
OKX is one of the world's largest and most feature-rich cryptocurrency exchanges, founded in 2017 and serving tens of millions of users globally. Originally known as OKEx, the platform rebranded to OKX in 2022 to reflect its expansion beyond traditional exchange services into Web3 tools, a built-in crypto wallet, and an NFT marketplace.
UK users can access OKX, though the platform is not currently registered with the FCA. It operates as an offshore exchange for British users. OKX has a strong reputation for its trading infrastructure, offering some of the lowest spot fees in the industry alongside advanced order types, trading bots, and a comprehensive derivatives suite.
For UK retail investors, the spot trading and simple purchase features are the most relevant. OKX's Simple Buy mode allows beginners to purchase crypto easily, while the Pro trading interface gives experienced traders access to some of the most sophisticated tools available on any exchange.

Supported Cryptocurrencies
OKX supports 350+ cryptocurrencies, giving UK investors access to a wide range of digital assets. Below are some of the most popular coins available on the platform.
Security
Security is one of the most important factors when choosing a cryptocurrency exchange. Here is how OKX protects your funds.
Cold Storage
The majority of customer funds are kept in offline cold storage — completely disconnected from the internet and unreachable by hackers.
Two-Factor Authentication (2FA)
All accounts can be protected with 2FA. Even if someone knows your password, they cannot log in without a second code from your phone or authenticator app.
Proof of Reserves
Regular reserve audits allow users to verify that the exchange holds sufficient funds to cover all customer balances.
Account Security Tools
Features such as withdrawal address whitelisting, anti-phishing codes, and login notifications help protect your account from unauthorised access.
Web3 Security
OKX's built-in Web3 wallet uses local key encryption, meaning your private keys are stored on your device — not on OKX's servers — giving you full control over your assets.
Ease of Use
OKX offers a two-tier experience: Simple Buy for beginners and a full Pro trading platform for advanced users. The Simple Buy interface is clean and intuitive — you select a coin, enter your amount, and purchase in a few steps.
The Pro trading platform is among the most powerful available on any retail exchange, with support for grid trading bots, DCA (dollar cost averaging) bots, arbitrage tools, and a wide variety of order types. For experienced traders, this level of functionality is rare at this fee level.
OKX also includes a built-in Web3 wallet and access to DeFi protocols and NFT markets directly from the app. While this makes OKX a very capable all-in-one platform, it does add complexity that newer investors may find unnecessary.
How to Open a OKX Account
Opening a OKX account is straightforward and typically takes 10 to 15 minutes.
Visit the Website
Go to the exchange website and click 'Create Account'. Enter your email address and choose a strong, unique password.
Verify Your Email
Check your inbox for a verification email and click the confirmation link to activate your account.
Complete Identity Verification (KYC)
Upload a valid photo ID (passport or driving licence) and proof of address. As a regulated platform, identity verification is required by law.
Wait 24 Hours (FCA Cooling-Off Period)
UK regulations require new users to wait 24 hours after registering before placing their first trade. Use this time to explore the platform.
Deposit Funds
Transfer GBP from your UK bank account using Faster Payments where available — it is usually free and arrives within minutes.
Enable Two-Factor Authentication (2FA)
Before trading, turn on 2FA in your account security settings. This is one of the most important steps you can take to protect your funds.
Start Buying Cryptocurrency
Search for a coin, enter your amount in pounds, review the fee shown, and confirm your purchase. Start small — there is no rush.

Crypto Tax in the UK
HMRC treats cryptocurrency as a capital asset. If you sell crypto for more than you paid, you may owe Capital Gains Tax on the profit. For the 2025–26 tax year, the annual CGT allowance is £3,000. Gains above this threshold are taxed at 18% for basic-rate taxpayers or 24% for higher-rate taxpayers.
From January 2026, all FCA-registered exchanges are required to report transaction data to HMRC automatically under the Crypto Asset Reporting Framework (CARF). Keeping your own records is still strongly recommended. Many investors use dedicated crypto tax software to calculate their liability accurately.
Final Verdict
OKX offers some of the lowest fees and most advanced trading tools of any exchange available to UK investors in 2026. For experienced traders who want a sophisticated platform with bots, Web3 tools, and tight spreads, it is an excellent choice.
For beginners or investors who prioritise FCA regulation, OKX is less suitable. Its offshore status and complexity make it better suited to those with some prior crypto experience who are comfortable using unregistered platforms.
