Background on CEX.IO

Formed in 2013 as a Bitcoin exchange, CEX.IO was a cloud mining provider as well.

CEX.IO provides a cross-platform trading feature via a website, mobile app, WebSocket and REST API, thus enabling access to excessive liquidity order book for well-known currency pairs on the market. Instant Bitcoin trading (purchasing and selling) is available via simplified bundle interface.

The exchange has created and advanced a multi-level account system with an individual advance/approach to each customer, from beginners being introduced to bitcoin including institutional traders as well.

Global coverage (network), a variety of payment options, and 24/7 support are escorted by time-given platform solidity that ensures the safety of the overall assets and data.

During the phase of its mining pool life, also known as Ghash.io, it had reached a level of being in control of 42% of the overall network mining power. On the other hand, during January 2015; the entire cloud mining functions were closed and currently CEX.IO performs exclusively as a Bitcoin exchange.

At present, CEX.IO is inscribed with FinCEN and it adopted KYC (know your customer) and AML (anti-money laundering) policies. This interprets that users will need to verify their identities before they would be able to purchase Bitcoins via the exchange.

CEX.IO enables their users to purchase Bitcoins using credit cards, a wire transfer or a SEPA transfer (if the respected user lives in the EU). But, CEX.IO online transactions operate a little bit different compared to other Bitcoin exchanges, they are formed on Fill-or-Kill orders (also known as FOK). FOK orders are directives that are implemented and carried out instantly and in full.

So in any case, if the users “agree” to pay or get, that’s exactly what will be expected of. This is disparate compared to how other exchanges work where they may face liquidity situations.

Relating this to an example, if the user wishes to purchase 2 Bitcoins at a particular rate on CEX.IO; then the user will definitely obtain the amount, although; if the users buy 2 Bitcoins on Bitstamp then the user will need to cease till someone who’s willing to trade off those Bitcoins when the requested price comes along.

But, for this to be initiated 100%; CEX.IO will need to invoice customers a premium so that they can be given the choice to fulfill their orders, thus the higher exchange rate.

How Does it Work?

CEX.IO has a comprehensible explanation on how their services operate as mentioned on the site, well; here’s a summary of it:

As the user enters the trade, CEX.IO identifies and calculates the price and suspends it for about 120 seconds. Therefore, the users will need to input the amount of money he/she wishes to expand and will finally view the number of Bitcoins obtained.

After the user enters the Buy/Sell Button, the system monitors and views whether if there are sufficient funds available for the trade. If the conditions on the market enable the implementation of the user’s particular order on specific conditions not dire compared to the ones which were concurred before, then eventually the order will be filled (The order can also be based and filled on more commendable conditions).

If there is a sudden incline in the exchange rate, there will be a prevention regarding the fulfillment of the order on the set conditions in which the user will be then notified. After the user confirms the trade, the order is then emulated to other orders present the exchange, thus the final balance is revamped — seldom; the amount placed can be even higher than agreed on, but it never on a small-scale.

After submission of these photos and completing the form, the users will be elicited to ensure and confirm that the information provided by the user up to date and authenticated. Users will also need to give approval for a company compliance officer in order to view the information.

If all the requirements regarding the exchange are met, then the user obtains an email notification heeding the user on the card’s active use which can be used now on the exchange. If any part of the information being provided by the user is not accurate, the compliance officer will notify the user about the elucidations and clarifications.

The process regarding the verification can last up to few hours or eventually up to a day. However, some users, have stated and described it even extended even for longer than a day.
