Certified coin is from Estonia. Whenever I hear Estonia all that come to my mind is positive. Okay! Let's talk on this exchange. It was in2019, it is a centralized exchange that trade few quantity of cryptocurrencies. The buying and selling of cryptocurrencies can only occur with use of some fiat currencies like the GBP, EUR, and 2 other type of fiat currencies. The Trading volume of this exchange cant be traced, I think the liquid is also have effect. I checked out for the telegram account I search certified coin but they all many accounts on certiied diamond coin but the main certified coin there in telegram has only 1 member with just 1 message on the group, I was seriously shocked. you can check this out. But I advice nobody should deposit here.
