CEX.IO was launched in 2013 as a cloud mining provider and a cryptocurrency exchange platform. CEX.IO is one of the most popular and widely used platforms for the buying and selling of cryptocurrencies. The cloud mining operations of CEX.IO got so huge that at one point, it controlled over 40% of the entire mining power. But the mining operations were shut down in 2015, and now it only operates as an exchange platform. There exist two ways of buying digital currencies on this website brokerage and a trading platform. The brokerage service is for new and novice users, and here CEX.IO will trade on your behalf at a premium. It is based on Fill-or-Kill (FOK) method, where orders are executed in full and promptly. The trading platform is for seasonal traders who have expertise in what they are doing. If you are facing any issue while using CEX.IO, contact Arcler Desk for our expert tech support.
