Registration and verification turned out to be quite labor-intensive. I understand that many exchanges face this issue, and Matbi is no exception. I struggled for two days with scans and screenshots, and I almost thought about giving up. But I felt sorry for the effort I had already put in. I have no complaints about the exchange itself. There are many thoughtful features, everything is convenient and clear. If you are an experienced professional, you will find interesting tools, including analytics.
