Is the affiliate program active? How can I sign up as affiliate?

Reply: Upbit does have a referral system, that offers a commission on referred users’ trading fees—potentially up to 50%. However, it does not operate like a full affiliate marketing program. Upbit maintains a referral or promotional code page for inviting new users..
