In today’s review, we will be looking at a popular UK-based exchange, CEX.IO, and analyze the features, security, pros and cons that come with this service.

CEX.IO Review: Exchange Overview


CEX.IO was first established in 2013 in London, starting out as a Bitcoin exchange and cloud mining service. Its mining pool was known as Ghash.io, and at some point in time, it managed to amass 42% of the total network mining power.

But in January 2015, CEX.IO closed its cloud mining operations, and now it only offers cryptocurrency exchange services.

The exchange is registered as a private limited company in the UK, and it is compliant with the FinCEN in the US and ICO in the UK, meaning it complies with standard KYC (know your customer) and AML (anti-money laundering) policies which require user identity verification.

Supported Currencies and Available Countries

CEX.IO supports 16 cryptocurrencies, including Bitcoin, Ethereum, Litecoin, Dash, Bitcoin Cash, Bitcoin Gold, Ripple, Stellar lumens, BitTorrent, Tron, Gemini Dollar, Zcash, Ontology, Ontology Gas, and MetaHash. It should be noted that with some crypto, you can only make deposits, buy, or trade.

The platform also supports four different fiat currencies:

  • United States dollar (USD);
  • Euro (EUR);
  • Pound Sterling (GBP);
  • Ruble (RUB).

CEX is registered to operate in 24 US States, but it is not supported in:

Alabama, Alaska, Arizona, Arkansas, Colorado, Florida, Georgia, Guam, Idaho, Iowa, Kansas, Louisiana, Maryland, Michigan, Mississippi, Nebraska, New Hampshire, New Jersey, North Carolina, North Dakota, Ohio, Oregon, Tennessee, Texas, U.S. Virgin Islands, Vermont, Virginia, and Washington.

The exchange is available in almost all countries, but there can be some restrictions on payment methods.

Iceland, Vietnam, Afghanistan, Algeria, Bahrain, Iraq, Kuwait, Lebanon, Libya, Nigeria, Oman, Pakistan, Palestine, Qatar, Saudi Arabia, and Yemen are restricted for credit card purchases.

Residents from these countries cannot make purchases via bank transfer: Afghanistan, Democratic Republic of the Congo, Côte d’Ivoire, Eritrea, Ethiopia, Guinea-Bissau, Haiti, Iran, Iraq, Kenya, Liberia, Libya, Guinea, São Tomé and Príncipe, Somalia, Sudan, Syria, Tanzania, Tunisia, Turkey, Vietnam, Yemen, and Zimbabwe.

CEX.IO Compatibilities

The platform can be used on all PC operating systems, web browsers, as well as iOS and Android devices.

User Interface and Experience

The website is aesthetic and intuitive, allowing you to find whatever you need with just one click. The trading interface has been reported to be user-friendly and has fast loading speeds.

The exchange also has a mobile app for both Android and iOS, which allows you to make crypto deposits, place limit market orders, view balances, and manage orders. But compared to the website services, the mobile app has just a fraction of its trading features. For instance, margin trading is not available on it.

The app has received both good and bad comments, with most complaints being about the app failing to execute orders, not displaying detailed graphs, and making it difficult to login in.

The exchange also provides an Application Programming Interface (API) for developers that want to create custom apps. There are three types of APIs: Rest for accessing market data, WebSocket for professional traders, and Fix for institutional traders.

The trading API has a limit of 600 requests per 10-minute interval, but capacities can be increased by contacting support.

Visa and MasterCard deposits have applied a fee that is a percentage of the total transaction and a separate small payment. CEX.IO has different fees based on the fiat currency used:

No fees are charged on the bank transfers and cryptocurrency deposits. All fiat currencies except Ruble can be transferred through banks.

Margin trading fees

CEX.IO applied a 0.2% fee to open a position with a leverage of 2 or 3, in addition to a rollover cost of 0.1%; when you close a position, there are no fees charged.

The biggest issue with CEX.IO is that it has hidden charges. The platform applies a 7% fee for its service, and that is why you will see the price of Bitcoin being higher than the current price displayed on other exchanges.

CEX.IO enables users to make deposits and withdrawals through a number of methods, including credit card:

  • Credit card;
  • Cryptocurrency;
  • Debit card;
  • Bank transfer (SEPA);

The platform has four different account levels depending on your identity verification status, and each account type comes with different buying limits and features.

Basic accounts have a maximum buy limit of $400 worth of bitcoins per day, and a monthly limit of $2,000. Deposit limits have a daily $1000 limit. Basic accounts cannot use bank transfers to buy, being limited to only with Visa and MasterCard purchases.

Verified accounts have a maximum daily purchase limit of $10,000 worth of bitcoins or a monthly maximum purchase limit of $100,000, with both credit card and bank transfer options.

Verified plus & Corporate accounts have no purchase limits.

Security Features

CEX.IO has, so far, never lost any funds due to hacking incidents. It keeps most of its cryptocurrency funds in cold wallets that are not connected to the internet.

The exchange is compliant with The Payment Card Industry Data Security Standard (PCI DSS), which attests that the provider can safely store, transmit, and process cardholder data. They also upgraded their PCI DSS Certificate to Level 2 in 2016, a top security standard.
