Thank you for using Bithumb.

Recently, phishing cases were reported on which persons misrepresenting themselves as the admin of Bithumb tried to
capture customer information by asking customers’ PC password, SMS verification code as well as OTP verification code.

Bithumb does not inquire your OTP verification code as well as your password under any circumstances.

Even if you receive a call/e-mail/SMS of this sort, do not respond
and report the case to us at (contact2@bithumb.com) or customer service center (1661-5566).

We will do the best to protect our customers’ personal information.

Thank you.
