If you are looking for ways how to buy BUSD for KRW, Utorg offers the easiest one, which consists of two steps:
The first step - setting up a purchasing order. It is necessary to provide the system with a currency pair (KRW-BUSD on BEP-20, Avalanche, or ERC-20), your actual BUSD crypto wallet, and the amount for purchasing.
The second step - paying for BUSD tokens. Just choose the most preferred way of paying (whether it is a credit card or Google Pay/Apple Pay) and complete the payment.
Bear in mind that you may be asked to complete identity verification, in case, if you use the services of Utorg for the first time.
