By the way, I wonder where you need to qualify for the KYC documents. On the sales website or on the exchange website. Both, here and there it is possible to upload your documents. It is a pity that the topic is rarely visited by team members. I think this is an important question.
I think it's the same, as long as you register using the same email wherever you verify whether on the sales website or on the exchange website, both of them will be verified as well.
