This is a centralized exchange focused on the European market. It was founded in 2019 and registered in Estonia. Certified Coins Exchange is an exchange that allows you to place orders for different cryptocurrencies, though limited. In other words, it deals mainly with buying and selling, and nothing more. Buying of cryptocurrencies here of course involves the use of fiat currency which in this case include EUR. Though, I came across a report that this exchange offered a wider range of fiat currencies like USD, RUB and GBP but I didn't see this myself. The liquidity provided by this exchange unknown as well as its trading volume. For an exchange like this, it's better to stay away than to toally risk your funds.
