Okay, so we have an interesting case here. A decentralized exchange with fiat withdrawal and KYC/AML. Benefits of a decentralized exchange are typically not having KYC/AML and transparency of transactions. Can you really call it decentralized when it depends on KYC/AML and an interconnection with a centralized exchange?
It doesn't have to be an anonymous, or even pseudonymous to be decentralized. Imho is enough if you own your own private key.
