CEX.IO

CEX.IO is a UK-based Bitcoin crypto exchange developed out of the first ever cloud mining provider.

History

CEX.IO project development started in early 2013 and proceeded with launching the CEX.IO domain, acquiring assets of GHash.IO and, finally, registering a legal company CEX.IO LTD in November 2013. By this time, according to Blockchain.info, GHash.IO has become the biggest mining pool, reaching over 42% of the overall Bitcoin mining power, which embodied the 51% attack threat. However, CEX.IO made an official statement, assuring the Bitcoin community that it would “take all necessary precautions to prevent reaching 51% of all hashing power, in order to maintain stability of the Bitcoin network.” In April 2014, CEX.IO user base exceeded 200,000 users. May 2014, CEX.IO imposed trade fee onto the exchange, lowered maintenance costs for cloud-based GHS and added IXC/BTC trading pair. On September 22, 2014, CEX.IO announced the successful launch of the first fiat currency — US dollars are accepted via bank transfer and payment cards. This upgrade allows users to trade Bitcoins and cloud-based hashing power (GHS) as well as deposit and withdraw funds at one place without using services of another exchange. On September 29, 2014, CEX.IO established the second fiat currency, the Euro, and implemented the possibility to deposit funds via SEPA. January 12th, 2015, CEX.IO suspended cloud mining services due to low Bitcoin price and high mining difficulty. Later on, CEX.IO has been developing as a trading platform. April 30th, 2015, the Bitcoin exchange has officially entered the USA market. CEX.IO has also obtained an MSB (Money Services Business) status in FinCEN, a bureau of the U.S. Department of the Treasury. As a registered MSB, CEX.IO has proved that the company complies with the Bank Secrecy Act requirements applicable to financial institutions as well as to each of the specific requirements applicable to MSBs. August 2015, CEX.IO added Russian Ruble as the third fiat currency. At the same time, the platform presented WebSocket API for professional traders. December 2015 is the release month of official CEX.IO Mobile Application. April 2016, CEX.IO launched Ether trading and added ETH/BTC and ETH/USD pairs. April 28th, 2016, CEX.IO launched withdrawals of USD, EUR, and RUB to payment cards (Visa/MasterCard).

CEX.IO claims to provide the best experience of buying Bitcoin with a payment card issued in any currency.

  • Payment card (Visa/MasterCard)
  • Wire transfer
  • SEPA transfer

API

CEX.IO application programming interface (API) allows users to access and control their account using custom written software. Trade API is limited to 600 requests per 10 minutes. Apart from Trade API, CEX.IO offers WebSocket API with pusher technology, due to which users are able to subscribe to certain exchange updates. Such subscription allows getting real-time notifications about system changes without sending extra requests to get required information.

Security

Users can secure their accounts with passwords, but CEX.IO strongly recommends using Two-Factor Authentication (2FA).

CEX.IO customers are free to use Google Authenticator[1] or get a text or an audio message containing respective authorization code.

CEX.IO is registered with the Information Commissioner’s Office (United Kingdom) as data processor and controller under registration reference ZA059396. The British ICO is an independent authority set up to uphold information rights in the public interest, promoting openness by public bodies and data privacy for individuals. Registration within ICO means CEX.IO complies with the European legislation on personal data privacy.

CEX.IO possessed a Level 3 PCI DSS (PCI Data Security Standard) certificate. According to the latter, CEX.IO is compliant with the standards and is able to store, process or transmit cardholder data of users. All data is strongly encrypted. Apart from that, each photo submitted by a user during the verification process, is encrypted with a separated encryption key.

Cloud Mining

Cloud mining or cloud hashing is a concept, which allows users to buy mining power of the hardware placed in remote data centres.

CEX.IO has been the first ever cloud mining provider working in conjunction with GHash.IO mining pool. According to CEX.IO business model, users were able to buy cloud-based GHS (mining power) to mine new Bitcoins on GHash.IO, and trade GHS on the exchange.

In January 2015, CEX.IO suspended cloud mining services taking into consideration users’ interests, significant Bitcoin price drop and upscaling of the mining difficulty. All GHS purchased by CEX.IO remained their absolute property.

Despite considerable Bitcoin price growth experienced in the last decade of 2015, it is still not enough for profitable Bitcoin mining, taking into account current difficulty and maintenance cost. And, provided the Bitcoin price won’t change much, there is no positive forecast for profitable mining in the nearest time.

Owners of cloud-based GHS on CEX.IO are free to choose 2 options:

  • let CEX.IO decide the mining behaviour (where we will be monitoring the mining difficulty and Bitcoin price and switch your GHS cloud mining power depending on profitability);
  • control cloud mining at their own risk (enable on their CEX.IO Profile > GHash.io tab > Turn off Let CEX.IO Decide > Turn on cloud mining).

CEX.IO focuses on developing as a Bitcoin exchange with two main services: easy Bitcoin buy/sell and professional Bitcoin trading.

Cross-Platform Trading

CEX.IO offers cross-platform trading via website, mobile app, WebSocket and REST API, providing access to high liquidity orderbook for top currency pairs on the market. Mobile application is available for free download on iOS and Android.
