Feature Breakdown
Kraken
Highlights
- FCA Registered (Dual): Kraken holds FCA registration as a cryptoasset business under the Money Laundering Regulations and FCA authorisation as an Electronic Money Institution (EMI) — one of the stronger UK regulatory footprints among crypto exchanges.
- Kraken Pro Order-Book Trading: Full maker/taker fee schedule with tiered pricing starting at 0.25%/0.40% — competitive for active UK traders who use limit orders.
- GBP Faster Payments Support: Supports GBP deposits and withdrawals via Faster Payments (FPS), making it one of the most UK-banking-friendly exchanges. FPS deposit options include some fee-free methods; FPS withdrawals cost £1.95.
- Advanced Account Security Tooling: Global Settings Lock and Master Key features provide user-configurable controls to prevent account takeover — more sophisticated than most mainstream rivals.
- Proof of Reserves Programme: Regular Merkle-tree style Proof of Reserves reporting with self-verification tooling, plus ISO/IEC 27001:2022 certification and SOC 2 Type 1 examination.
UK Considerations
- Account Holds & Compliance Restrictions: The most repeated UK complaint — accounts or funds being placed on hold during AML/KYC reviews, often with limited explanation and slow resolution via support tickets.
- Instant Buy/Sell Cost Trap: UK users who do not use Kraken Pro pay a fixed 1% fee plus spread; the total effective cost is frequently higher than expected and not clearly surfaced at the point of purchase.
- FPS Withdrawal Delays: While Faster Payments is the default GBP rail, some UK users report withdrawals remaining 'pending' for longer than Faster Payments implies, particularly during high-volume periods.
- UK Retail Derivatives Restriction: UK retail users cannot access derivatives products; access is limited to those meeting professional client criteria.
- Staking Eligibility Confusion: Kraken's Opt-in Rewards messaging indicates UK restrictions for some reward types, while staking pages still promote the product — creating confusion about what UK residents can actually access.
OKX
Highlights
- Lowest Trading Fees: 0.08% maker / 0.10% taker at base tier — among the cheapest in the industry.
- Advanced Trading Tools: Professional charting, advanced order types, futures, options, and perpetual swaps.
- Built-in Web3 Wallet: Access DeFi protocols, NFTs, and decentralised applications directly from the OKX app.
- Copy Trading: Follow and automatically replicate the strategies of successful traders.
- 350+ Cryptocurrencies: Wide selection with deep liquidity on major trading pairs.
UK Considerations
- Not FCA Registered: No FCA registration means no FSCS protection and no Financial Ombudsman access for UK users.
- No Direct GBP Support: Cannot deposit or withdraw GBP directly — must use third-party providers (MoonPay, Banxa) with 3-5% fees.
- Complex for Beginners: The advanced interface is powerful but overwhelming for users new to crypto trading.
- Regulatory Uncertainty: While compliant with FCA financial promotions regime, the lack of registration creates ongoing uncertainty.
- Third-Party Fiat Fees: The 3-5% cost of buying crypto via card through third-party providers significantly increases the effective cost.
