https://www.coindesk.com/korean-exchange-bithumb-is-accepting-new-users-again/South Korean cryptocurrency exchange Bithumb is now accepting new investor registrations following integration of new regulator-mandated "know-your-customer" (KYC) procedures.
In an announcement on its homepage, Bithumb said that, starting from Feb.9, investors on the platform will be able to confirm their real identity through accounts at Nonghyup Bank. The firm further detailed that KYC integration with Shinhan Bank is also being pursued.
The integration arrives just 10 days after a formal ban on anonymous virtual trading accounts in South Korea. As reported by CoinDesk, the country's Financial Services Commission (FSC) had mandated that all cryptocurrency exchanges in the country must introduce real-name verification procedures for all customers via domestic banks by Jan. 30.
It looks like you need to have an account at an approved bank before you can open an account at Bithumb, and they are using the bank's verification process to identify the bithumb account holder.
