Bithumb promo & referral 2026 — Korea's #2 exchange
Bithumb is the second-largest South Korean crypto exchange after Upbit, holding roughly a quarter of the domestic KRW market. The 2026 product is FSC-registered as a Virtual Asset Service Provider, uses NH Bank for real-name fiat onboarding, and regularly runs aggressive zero-fee promotional events on specific KRW pairs — historically the most effective acquisition mechanic in Korean retail crypto.
Bithumb — the Korean #2 that competes on aggressive promotions
Bithumb was historically the dominant Korean crypto exchange before Upbit overtook it in 2018. Today Bithumb holds approximately 25% of domestic KRW trading volume — a clear #2 position in the duopoly that runs Korean retail crypto. The platform competes with Upbit primarily on two axes: aggressive zero-fee promotional events on selected KRW pairs (the most effective customer-acquisition mechanic in the Korean market), and faster new-token listing pipelines for emerging projects. Bithumb has been in IPO preparation on the KOSDAQ for several years; a successful listing would significantly improve regulatory anchoring.
Activation flow
Sign up at bithumb.com with a Korean phone number and resident registration ID. Open an NH Bank account if you do not already have one — Bithumb's exclusive partnership with NH Bank handles all KRW real-name fiat onboarding, in line with FSC requirements. Complete the FSC-grade KYC (real-name verification linking your NH account to your Bithumb account). Deposit KRW. Promotional bonus tickets and trading-fee rebates are credited to qualifying new users during seasonal campaigns — these vary by quarter and are typically tied to first-deposit and first-trade thresholds.
Zero-fee KRW pair mechanics
Bithumb has historically run aggressive zero-fee promotional periods on specific KRW pairs — entire weeks or months where the maker/taker fee on a designated pair drops to 0%. This is the only fee schedule in Korean crypto where Bithumb is materially cheaper than Upbit. The pairs rotate, so this is a tactical advantage rather than a permanent fee schedule. For traders who can monitor the promotional calendar and align trades, the savings can be meaningful (Bithumb's standard fee is 0.25% maker/taker; zero-fee promo saves 50 bp per round-trip).

Editor's personal take
Bithumb is the Korean exchange where the promotional calendar matters. If you are a Korean trader who can align meaningful volume with a zero-fee KRW pair window, Bithumb's economics are genuinely competitive with Upbit. If you are not actively chasing promos, Upbit's deeper liquidity and lower standard maker fee make it the default. For foreign users (who cannot register anyway), Bithumb's relevance is mostly as a price-discovery data source for Korean retail sentiment.
