Xcalibra exchange is a centralized exchange that established in the year 2019 which deals in exchange of different crypto currencies all over the world,this platform was available to about a 100+ countries with African countries being omited. I tried to register but because my nationality was not listed, I was unable to register. The Xcalibra exchange has a very attractive interface which showed me the requirements needed to open am account which was actually not possible, my phone number was requested, my email address, a strong password, my agreement to the terms and conditions and additional documentation was provided to confirm my identity. From the interface I could see that the exchange has automated backups and IP security and access restrictions.
I also visited their Twitter group which was very active and created a bond between users all over the world
