South Korean crypto exchange Coinone said it would no longer accept withdrawals from unauthenticated external wallets. This announcement was made in January.

Coinone announced Wednesday that it would be launching a new product. Users would need to register external wallets with the exchange between December 30 and January 23. After that, withdrawals would be restricted. The exchange specified that crypto users could only register their own wallets, and the verification process “may take some time” and could change in the future.
