Korean exchanges vs offshore venues

Korean won-market exchanges, Bithumb, Coinone, Korbit, Gopax, trade spot only, against the won, to users with a verified Korean bank account. Offshore venues like Binance, Bybit and OKX trade perpetual futures with leverage, in USDT, to almost anyone else. These are different products serving different needs, and the fact that both are called 'crypto exchanges' obscures how little they overlap.

A Korean trader typically uses both: the domestic exchange to convert won into crypto through the banking system, and an offshore venue for derivatives, which licensed Korean exchanges do not offer to retail users at all.

This is where comparing them causes real confusion. Offshore exchanges run affiliate programmes: an affiliate receives a share of trading fees for as long as the referred user keeps trading, and typically passes part of that back as a standing fee discount. The value compounds with volume and time.

Korean exchanges run consumer invite schemes. A new user enters a code, meets some qualifying condition, usually connecting a verified bank account, and both parties receive a one-off reward. There is no ongoing share of fees, and there is no fee discount. Once the reward is paid, the relationship stops producing anything.

There is no exception among the four. The reward is paid once and nothing continues, which is the single most useful thing to know before weighing a Korean invite bonus against an offshore fee discount. They are not the same kind of value, and only one of them compounds with volume.

Korean spot base rates range from 0.05% to 0.25% depending on the venue, with coupon and voucher routes reaching 0.04% at two of them. Offshore futures fees are 0.02% or less on the maker side. Those numbers look like they belong on the same scale and they do not — one is a spot trade in won, the other is a leveraged derivative in USDT, and the risk involved is not remotely similar.

The comparison that does make sense is within each category. Among Korean exchanges, Korbit at 0.05% is four times cheaper than Gopax at 0.20% before any coupon is involved, and that is a straightforward and meaningful difference. Among offshore venues, the maker-taker structure and the referral discount decide it. Across the two, there is no meaningful comparison to make.

Korean exchanges require a verified real-name bank account at a Korean bank, Korean resident identity verification, and a Korean mobile number. This is a regulatory requirement under South Korea's real-name transaction rules, not exchange policy, and there is no workaround. If you are not a Korean resident, these venues are closed to you regardless of what any referral page implies.

Offshore venues are open to most of the world but maintain their own restricted lists, which commonly include the United States and vary elsewhere. Both categories have hard access limits; they are just different limits.
