Feature Breakdown
Gemini
Highlights
- FCA Dual Registration: Gemini holds FCA registration as a cryptoasset business under the Money Laundering Regulations and FCA authorisation as an Electronic Money Institution (EMI) — one of the strongest UK regulatory footprints available.
- GBP Faster Payments Support: Supports GBP deposits and withdrawals via Faster Payments, enabling quick and low-friction fiat on/off ramps for UK users.
- Gemini Active Trader: A professional-grade trading interface with advanced charting, analytics, and a maker/taker fee schedule for experienced users.
- On-Chain Staking: Staking available for ETH and SOL, with rewards paid directly to user accounts.
- Strong Security Posture: SOC 1 and SOC 2 Type 2 certifications, active bug bounty programme, and 1:1 Proof of Reserves. Industry-leading cold storage practices.
UK Considerations
- Limited Coin Selection: Gemini offers 70+ cryptocurrencies — solid for major assets but significantly fewer than rivals like Kraken or Crypto.com, which may disappoint altcoin traders.
- Customer Support Wait Times: A recurring theme in negative reviews is slow email support response times, particularly for account verification and fund access queries.
- Staking Availability: ETH and SOL staking is available, but the range of stakeable assets is narrower than some competitors.
- UK Retail Derivatives Restriction: UK retail users cannot access derivatives or margin products in line with FCA rules.
- Higher Instant Buy Fees: Convenience fees on instant purchases are higher than the Active Trader maker/taker schedule — users should use Active Trader where possible to manage costs.
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.
