Fees & Total Costs

Spot Maker/Take

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.

Spot trading fees follow a tiered VIP structure based on your 30-day trade volume and holdings of the native ASD token; larger volume or ASD holdings unlock lower maker and taker rates, especially for major market-cap pairs.

Futures/Derivatives

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).

Futures (perpetual) trading uses its own VIP-based fee tiers—maker fees can be as low as around 0.02%, takers around 0.05%—and funding payments occur every eight hours to align perpetual contract prices with spot.

Average Spreads on Liquid Pairs

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.

Liquid pairs like BTC/USDT and ETH/USDT exhibit tight spreads thanks to deep order books and efficient matching, making execution cost minimal beyond standard fees.

Fiat Deposits & Withdrawals

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.

You can fund via credit/debit card or bank transfers through third-party processors; while deposits are quick, they may include a dynamic processing fee; withdrawal options and speeds depend on your local banking rails and chosen method.

On-chain Withdrawals

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.

BTC, ETH, TRX, etc.)

Hidden Costs

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.

Implicit costs may arise from conversion markups when buying crypto with fiat, inactivity penalties, or optional fast-track identity verification services, so even if explicit fees are low, these can add to your total cost.

Real-World Cost Example: “€500 BTC

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.

When you convert €500 into BTC, costs include the processing spread from fiat to crypto, the trading fee on your spot purchase, and any withdrawal network fee—so the net BTC received will be noticeably less than the €500 equivalent due to layered transaction components.

Crypto Offering & Trading Features

Number of Coins & Pairs

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.

AscendEX supports over 200 to 300 cryptocurrencies across more than 200 trading pairs, with the most liquid top 20 pairs typically dominated by BTC, ETH, USDT, and popular large-cap and DeFi tokens if ranked by volume.

Product Range

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.

The platform offers spot, margin, and perpetual futures, flexible staking and yield programs, copy-trading for futures, and supports automated strategies such as grid bots and DCA through its API and third-party tools—though options and crypto ETFs are not part of the current offering.

Liquidity

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.

With a reported 24-hour trading volume ranging from hundreds of millions to a couple of billion dollars, BTC/USDT and ETH/USDT markets offer strong depth and tight order books, enabling efficient execution even for substantial orders.

Tools

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.

AscendEX features a full suite of order types (limit, market, stop, OCO), advanced charting with customizable indicators, real-time alerts, and robust API/WebSocket access—although it relies on its proprietary charting tools rather than native TradingView integration.

Geographic Restrictions by Product

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.

Certain regions face limitations such as no access to futures or derivatives features—specifically, users in jurisdictions like the United States and China are restricted from using these products due to compliance considerations.

Innovation

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.

AscendEX delivers early access to new token projects via its launchpool platform, and its Earn suite includes both flexible staking options—as well as programs with lock-up periods—giving users choice in how they deploy assets to generate yield.

Security, Regulation & Custody

Operating Entity & Jurisdiction

CEX.IO operates through several entities

AscendEX operates under AscendEX Technology S.R.L., legally established in Romania, while the broader group includes BMXDM Technology Pte. Ltd. founded in 2018, with headquarters primarily in Singapore.

Licenses/Registration

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.

The platform adheres to AML/CTF regulations where required, but does not currently hold formal regulatory licenses such as VASP in most jurisdictions nor EU MiCA authorization.

Custody

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.

Users’ crypto assets are stored primarily in cold, offline wallets managed directly by AscendEX, supported by a defense-in-depth security model; there’s no publicly disclosed proof-of-reserves audit or specific percentage of assets held in cold storage.

Insurance & Protection Funds

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.

AscendEX maintains an internal insurance fund drawn from its own balance sheet to cover potential losses in the event of security incidents.

Incident History

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.

In December 2021, AscendEX suffered a hot-wallet exploit across several blockchains, but fully reimbursed all impacted users and rebuilt its infrastructure with stronger safeguards.

Risk Controls

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.

The platform supports two-factor authentication, device monitoring, anti-phishing alerts, and offers API access with control options and sub-account structuring to help manage risk.

Transparency

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.

While offering real-time monitoring and reporting tools, AscendEX does not publish monthly reserve statements, public wallet addresses, or formal service-level agreements.

Deposits, Withdrawals, KYC & Support

Fiat Deposit Methods

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.

AscendEX supports depositing fiat through third-party providers such as Simplex, MoonPay, Mercuryo, and Banxa via card or bank transfer, offering fast funding for multiple regions, with specific minimums and maximums varying per provider and region.

Supported Fiat Currencies & Conversion

KYC (Verification Levels)

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.

AscendEX requires identity verification for full platform access; unverified accounts face strict withdrawal caps (such as 0.75 BTC daily), while verified users enjoy much higher limits, with further tiered levels unlocking even greater flexibility.

Withdrawals

Limits, Timing & Networks

Withdrawal limits depend on KYC status—unverified accounts are capped at around 0.75 BTC per day, verified users far higher—and users can withdraw via multiple networks (ERC-20, TRC-20, BEP-20, etc.), with processing speed tied to blockchain congestion.

Customer Support

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.

AscendEX offers round-the-clock support via live chat and email, with a comprehensive help center available for self-service; response times generally fall within reasonable hours though may vary based on query complexity.

Languages & Localization

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.

The interface supports multiple languages including English, and displays prices in common currencies like EUR and USD; it also tailors functionality—and availability—to comply with regional regulations.

App Quality & Stability

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.

The AscendEX mobile and desktop apps deliver a polished and responsive experience, receiving regular updates to bolster stability and features, with no widespread reports of performance or crash issues among users.

Experience, Performance & Ecosystem

UX/UI

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.

The platform provides both a streamlined “Lite” interface optimized for newcomers and a feature-rich “Pro” mode tailored for experienced traders, offering intuitive navigation while allowing users to progress as their skills evolve.

Performance

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.

Order execution is generally fast and stable, though sharp market spikes can occasionally lead to slight delays; during bull runs, KYC processing times may lengthen, though the platform scales verification capacity to mitigate backlogs.

Education

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.

AscendEX hosts an educational hub with articles, investment lessons, and futures tutorials, but it does not currently offer demo trading accounts or Spanish-specific learning modules.

Community

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.

Users can connect via numerous official Telegram channels across multiple languages and leverage an active referral program that rewards users for inviting others to the platform.

Integrations

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.

The exchange offers native TradingView charts and robust API access, enabling integration with third-party bots and tax/accounting tools like CryptoTaxCalculator for portfolio tracking and reporting.

Who Each One Is Best For

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.

Beginners benefit from the Lite mode and educational resources, active/pro traders gain from the advanced order tools and integrations, and those focused on passive strategies can leverage the automated tools and referral rewards.
