KYC (Know Your Customer) is a standard verification procedure.
To complete the basic version of the verification, just open your Profile and select the "Personal" tab.
After that, add your personal information and save it on the second page.
Make sure all the personal data is correct, and both pages are filled in.
Click "Save" after everything is done.
No worries, all the personal data is protected, and no third parties have access to it.
