Fees & Total Costs

Spot Maker/Take

CMC Markets does not operate a traditional maker/taker fee structure or tiered volume discounts and does not offer any cost reductions tied to a native token.

CEX.IO’s spot trading fees begin at 0.25% for taker orders and 0.15% for maker orders, and progressively decrease as your 30-day trading volume rises—reaching lower bands (like around 0.10%) at higher volumes, with no discounts tied to a native token.

Futures/Derivatives

CMC Markets provides CFDs and spread bets on derivatives, but it does not publish distinct maker/taker pricing or funding rates as you’d find on crypto futures exchanges.

CEX.IO separates its derivatives platform from spot trading and applies different fee structures, but publicly available information on specific maker, taker, or funding rates is limited (often requiring account access or direct inquiry for clarity).

Average Spreads on Liquid Pairs

For major crypto pairs like Bitcoin and Ethereum, the platform offers relatively tight spreads—even for top-tier tokens—thanks to aggregated pricing feeds and fast execution.

Spreads for major pairs like BTC/USDT and ETH/USDT on CEX.IO are generally tight and in line with competitive market norms, helping ensure that trading costs remain low for highly liquid assets.

Fiat Deposits & Withdrawals

Users can fund their account via bank transfers or cards; processing times vary by method, and while there may be standard processing delays, no explicit deposit or withdrawal fees are highlighted.

You can fund your account using various options—credit/debit cards, bank transfers (SEPA, SWIFT, ACH), digital wallets, and alternative services—with timing and fees varying by method and region, and listed transparently during transaction setup.

On-chain Withdrawals

CMC Markets does not support direct withdrawals to crypto wallets, so there are no on-chain network fees—either fixed or dynamic—to consider.

On-chain withdrawal fees differ depending on the blockchain (BTC, ETH, TRX, etc.) and are dynamically adjusted based on network conditions, rather than using a one-size-fits-all flat fee.

Hidden Costs

While the platform primarily centers on spreads and overnight costs, indirect expenses may include currency conversion margins or potential costs if accounts go dormant, though these are not prominently marketed.

Beyond trading and transfer fees, there may be extra charges lurking in currency conversion margins, inactivity fees, or expedited KYC processing—but these are typically disclosed at the relevant step, not built into everyday trading.

Real-World Cost Example: “€500 BTC

If you purchased €500 worth of Bitcoin through CMC Markets via CFDs, your effective cost would stem from the spread on the BTC position; since direct crypto ownership and withdrawals aren’t offered, you wouldn’t incur any separate withdrawal costs—just the cost implied by spread and position closure.

If you were to convert €500 into BTC, your total cost would combine the spot maker/taker fee, the market spread, and any withdrawal or conversion fee—resulting in a composite cost slightly above the raw crypto amount, depending on your payment method and network chosen.

Crypto Offering & Trading Features

Number of Coins & Pairs

CMC Markets offers CFDs on more than 35 cryptocurrencies—including Bitcoin, Ethereum, Litecoin, XRP, meme coins, and newly added altcoins—though it doesn’t show distinct listings for “top 20 by volume.” Their platform also provides indices that bundle both major and emerging crypto for broader exposure.

CEX.IO currently lists around 280 cryptocurrencies across approximately 829 trading pairs, with its highest-volume pairs including BTC/USD, ETH/USDT, ETH/USD, XRP/USD, LINK/USD—forming the bulk of daily activity.

Product Range

All crypto offerings come exclusively as leveraged derivative CFDs or spread bets; there’s no true spot crypto, no futures/perps, options, ETFs, staking, lending, copy-trading, grid bots, or automated DCA tools available.

CEX.IO supports spot trading, margin trading with up to 10x leverage, crypto staking and savings, and lending services; however, it does not currently offer perpetuals, options, ETFs, automated DCA, grid bots, or copy trading tools.

Liquidity

While CMC doesn’t disclose specific 24-hour volumes or depth metrics, its aggregated pricing across multiple sources ensures consistently deep, responsive liquidity, especially for BTC and ETH.

Reported 24-hour trading volume on CEX.IO ranges in the tens to hundreds of millions of USD, with robust liquidity in major pairs like BTC and ETH—offering sufficient depth for swift execution without significant price impact.

Tools

The platform supports advanced trading features, including limit, stop, and OCO orders, real-time alerts, rich charting tools (including native TradingView integration), and robust API and WebSocket access for automated trading.

The platform provides basic order types such as limit and stop (plus OCO where available), access to advanced charting via its trading terminal, real-time price tracking, alerts, and full-featured APIs (REST, WebSocket, FIX on Prime) ideal for automated strategies.

Geographic Restrictions by Product

Certain products like CFDs and spread bets are unavailable in jurisdictions that ban them—such as the U.S.—meaning crypto derivatives are accessible only in regions where CFD trading is permitted under local regulation.

Certain features—including margin trading, staking, savings, and advanced product access—are restricted or unavailable in specific countries due to jurisdictional licensing and compliance requirements.

Innovation

CMC Markets does not offer crypto-focused innovation services like launchpads, launchpools, or flexible/locked staking; its emphasis remains on delivering traditional CFD-based trading experiences rather than DeFi-style earn mechanisms.

CEX.IO offers flexible staking and savings options under its “Earn” program that allow on-demand access to funds; however, it does not currently support token launchpad or launchpool initiatives.

Security, Regulation & Custody

Operating Entity & Jurisdiction

CMC Markets plc, founded in 1989 and headquartered in London, operates globally with regional subsidiaries under local regulatory oversight.

CEX.IO operates through several entities

Licenses/Registration

The firm holds multiple high-tier licenses—including from the UK’s FCA, Germany’s BaFin, Australia’s ASIC, Singapore’s MAS, and Canada’s CIRO—providing broad regulatory coverage.

The exchange holds a U.S. Money Services Business registration with FinCEN and multiple state-level money transmitter licenses, a Gibraltar DLT provider license, Spanish VASP registration, and Lithuanian VASP status, reflecting a broad regulatory coverage across major markets.

Custody

Client deposits are segregated in reputable banks and undergo daily reconciliations and annual audits, though no public proof-of-reserves or cold storage percentages are provided.

CEX.IO maintains a layered custody model—hot wallets with PCI DSS-compliant security and cold wallets secured via multi-signature and manual controls; fiat is held in segregated bank accounts—though no formal public proof-of-reserves disclosures or third-party audits are noted.

Insurance & Protection Funds

Eligible retail clients benefit from compensation schemes such as the UK’s FSCS and Canada’s CIPF, alongside negative balance protection, where applicable.

While CEX.IO provides FDIC insurance for USD balances held within participating U.S. banks up to typical limits, there is no general insurance for crypto assets beyond its rigorous internal security protocols.

Incident History

CMC Markets has a clean cybersecurity record with no reported hacks or major incidents, though it faced legal scrutiny over CFD practices in Australia and regulatory breaches in past years.

The platform maintains a clean operational record with no major security breaches, public incidents, service suspensions, or regulatory penalties reported to date, underlining its reputation for reliability.

Risk Controls

The platform offers strong security features including two-factor authentication (via app or SMS, required for withdrawals), encrypted data, anti-fraud mechanisms, and secure API access.

User protection is reinforced with mandatory KYC/AML procedures, two-factor authentication, address whitelisting, a proprietary transaction-monitoring system, and granular APIs aimed at enhancing security and user control.

Transparency

CMC Markets provides regular reporting on execution quality and fund segregation, but does not publish public wallet addresses or formal SLA guarantees.

CEX.IO does not publish monthly financial or operational reports, nor provide public wallet addresses or formal service-level agreements (SLAs), although its regulatory compliance and security stance contribute to overall trust.

Deposits, Withdrawals, KYC & Support

Fiat Deposit Methods

CMC Markets accepts deposits via bank transfer, credit/debit cards, and sometimes e-wallets; card deposits can go up to around $50,000 per transaction (depending on card issuer), while bank limits depend on your bank, and funds are typically available almost instantly for cards or on the next business day for bank transfers.

CEX.IO allows fiat deposits via bank cards (Visa/Mastercard), bank transfers (SWIFT, SEPA, ACH, Faster Payments), and e-wallets like Skrill and PayPal; limits depend on verification level—new users may be capped at around $1,000 daily and $3,000 monthly, with standard limits applied after three months—and deposits typically arrive instantly (for cards/e-wallets) or within 1–3 business days (for bank transfers) depending on the method and region.

Supported Fiat Currencies & Conversion

KYC (Verification Levels)

You must complete identity verification before trading; while CMC does not publish tiered verification levels or trading limits, verification is mandatory for full access and withdrawal capabilities.

CEX.IO enforces at least identity verification for full access to fiat features like card and transfer services; preliminary verification allows limited use, while higher account tiers—such as Enhanced or Corporate—lift deposit/withdrawal limits and enable large-scale operations.

Withdrawals

Withdrawals are possible via card, bank transfer, or PayPal (where available); there’s a daily cap (e.g., ~$40,000 to card, up to €10,000 to PayPal), unlimited withdrawals to registered bank accounts, and typical processing ranges from same-day to a few business days; direct crypto withdrawals (TRC20/ERC20/BEP20) are not supported.

Limits, Timing & Networks

Customer Support

CMC Markets provides support through email, phone, and live chat (operating during business hours), supported by a rich knowledge base—response times vary but generally align with office hours.

Users have access to help via live chat (mobile and web), email support, and an extensive knowledge base containing guides and FAQs—but response times vary and are influenced by location and request complexity.

Languages & Localization

Services are localized across regions—platforms often display in local languages (including native Spanish where available), show pricing in local fiat (€, etc.), and operate under applicable local regulations.

The platform is fully available in English (as its primary language), and shows amounts in USD or EUR depending on region; local regulatory compliance is reflected in the user’s jurisdiction which affects available payment methods and features.

App Quality & Stability

The mobile and desktop apps are regularly updated and known for robust stability, with very low crash rates reported, though exact metrics aren’t published—users generally report smooth and reliable performance.

The CEX.IO app boasts a solid level of stability with regular updates; while precise crash rates aren’t publicly disclosed, the platform emphasizes performance enhancements and bug fixes in app release notes to deliver a smooth user experience.

Experience, Performance & Ecosystem

UX/UI

CMC Markets’ flagship interface, Next Generation, is feature-rich and award-winning, offering saved layouts and module linking for efficient navigation; while there’s no explicit “Lite” mode, their platforms cater to both seasoned traders (via advanced tools and customizable dashboards) and those who prefer a streamlined setup.

CEX.IO offers a single unified interface rather than separate “Lite” or “Pro” views, relying on straightforward layout and intuitive navigation to help both new and experienced users pick up functionality quickly and seamlessly.

Performance

Their co-located London data centers and proprietary API connectivity deliver low-latency order execution—even under high loads—though occasional freezing or slippage can happen during peak volatility; KYC processing tends to follow regular timing without widespread reports of long queues during market surges.

The platform benefits from institutional-grade infrastructure designed to minimize order latency, but like many exchanges, occasional slowdowns can surface during extreme market volatility; onboarding generally remains efficient even during high-demand periods.

Education

CMC Markets offers a rich education suite including video guides, platform tutorials, webinars, and articles, plus a risk-free demo account that stays active indefinitely and supports strategy testing—with materials often localized, including Spanish-language versions in select regions.

CEX.IO University delivers free, beginner-friendly crypto education with a comprehensive glossary and lessons ranging from basic to advanced levels—though it currently lacks a live demo or simulator, and content in Spanish is available through its educational portal.

Community

The platform includes an integrated trading forum where users can share strategies and sentiment, however CMC does not officially promote Discord or Telegram channels, and while referral programs may exist regionally, they’re not prominently advertised.

The ecosystem includes an affiliate and referral program to reward users for spreading the word, but it does not prominently feature official forums or active Discord/Telegram communities as part of its outreach.

Integrations

Users benefit from native TradingView-grade charting and pattern tools, plus API/WebSocket access for third-party automation, although there’s no direct integration with tax-reporting or portfolio accounting platforms.

The platform integrates TradingView for charting, offers fully featured APIs for external bot support, and allows data export for tax and accounting purposes, making it viable for integration into broader trading and reporting workflows.

Who Each One Is Best For

The platform is ideal for analytical, advanced traders who value deep charting tools, customization, and learning resources; it may be less suited to those seeking social trading, mobile-first simplification, or integrated accounting and bot ecosystems.

CEX.IO is particularly well-suited for users seeking a balanced and compliant entry into crypto—from beginners who want ease of use and educational resources to semi-advanced traders needing reliable tools and external integration capabilities.
