What is CEX.io?

CEX.io is a Bitcoin exchange platform which also accepts fiat currency. Founded in London, CEX.io first started as a mining pool back in 2013 and over time it developed into a multi-functional cryptocurrency exchange.

At one point in time, CEX.io used to own nearly half of all the mining power available (42% of Bitcoin hashing power). It used to offer cloud mining services up until 2015, but now it operates just as a cryptocurrency exchange.

To be allowed to accept fiat funds from clients, they are regulated as a payment provider but they are not managed by the Financial Conduct Authority. This may not sit well with experienced fiat traders, but it must be noted that FCA does not regulated companies that operate in the crypto hemisphere.

The platform lets users to trade on its web and mobile app, WebSocket and REST API.

The trading platform

CEX.io’s services can be accessed via a web based platform. It has the advantage that it can be used on any device without installing additional software. While it looks pretty functional, but the trading activity is displayed on only one single page which doesn’t provide sufficient input for technical analysis.

Mobile app

The app version of CEX.io offers only a small part of the services available on the web platform. Customers often complain about how the app fails to execute orders, has difficulty logging in, and does not display detailed graphics.


This programming interface was made for developers so they can customize and create their applications for trading their assets. There are three variations of the API: WebSocket (for experienced traders), Fix (for institutional traders) and Rest for accessing market data.

The trading limit is 600 requests per a 10-minute interval, and if developers want to increase the trading limit, they must contact support.

Security and safety

CEX.io has not seen a major hack so far. But there have been plenty of reports from clients that claim to have received emails that inquired about personal information, after their registration on the website.

CEX.io has negative balance protection for margin positions, a feature that will be very useful when facing aggressive traders.

There are very many clients that have given negative reviews, most of the complains being linked to the slow KYC procedures.
