I have EU based company registered as crypto exchange with EU iban.
I have EU based non crypto company with EU iban.
I have UK based non crypto company with EU iban and UK account.
I have offshore based non crypto company with EU iban.
I can exchange with full KYC procedure or without trough any of these companies.
Can you share your the names of your 4 companies? I'm quite curious how you can be registered as an exchange, and at the same time ignore KYC regulations by using a different company.
