Feature Breakdown
CoinJar
Highlights
- FCA Registration: CoinJar UK Limited is listed on the FCA cryptoasset register, confirming it meets UK AML/KYC regulatory standards for crypto businesses.
- GBP Faster Payments: Supports instant GBP deposits via Faster Payments and GBP withdrawals, with no deposit fee — one of the most frictionless GBP on-ramps available to UK users.
- CoinJar Card: A Visa debit card that allows users to spend crypto directly for everyday purchases, with automatic conversion at point of sale.
- CoinJar Exchange: A professional trading interface with advanced charting, 200+ trading pairs, and a competitive maker/taker fee structure for experienced traders.
- Long-Established UK Presence: Operating in the UK since 2014 — one of the longest-running crypto exchanges available to UK users.
UK Considerations
- Limited Coin Selection: CoinJar supports 60+ cryptocurrencies — sufficient for major assets but fewer than most rivals, limiting options for altcoin traders.
- No Staking or Yield Products: CoinJar does not currently offer staking or earn/yield features, which may disappoint users looking to generate passive income from holdings.
- Smaller Global Footprint: Less well-known globally than Coinbase or Kraken, which may give some users pause despite its strong UK regulatory standing.
- UK Retail Derivatives Restriction: Derivatives and margin products are not available to UK retail users in line with FCA rules.
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.
