Bithumb, one of South Korea's largest cryptocurrency exchanges, says it will open a new decentralized exchange, Bithumb DEX, to target the global market

Context & Ripple Effects
Bithumb's push into decentralized trading is a direct response to its own custody record: a 2017 breach that exposed user data to phishing attacks was followed by a ~$31M hack in June 2018 that forced a suspension of deposits and withdrawals. A centralized exchange holding customer assets had now failed twice, and Korean regulators were tightening around domestic platforms.
The DEX announcement also lands mid-ownership upheaval — within a week Bithumb confirmed it had sold more than 38% of itself to BK Global Consortium for $350M ([[a:934415]]), meaning the new buyers inherit both the security liabilities and this global-market pivot. Later coverage shows the strategy's stakes: by the time of Bithumb's 2025 IPO run, Kaiko put its share of Korean crypto trading at 36%, up from 11.5% a year earlier.
First-order effects
- Global traders gain a Bithumb-branded venue that does not require routing funds through the hacked custodial infrastructure of the Korean exchange, decoupling the brand from its worst security history.
- Bithumb's new majority owner, BK Global Consortium, gets a growth asset positioned outside Korea's regulatory perimeter just as it takes control of the domestic business.
Second-order effects
- Rival Korean exchanges face pressure to follow with their own offshore or decentralized venues, since Bithumb is effectively competing against them from outside the jurisdiction they all operate in.
- Liquidity on the Korean won books risks splitting between the regulated exchange and the DEX, forcing Bithumb itself to manage two order books under different rule sets.
Third-order effects
- If the pattern holds, regulated national exchanges increasingly use DEX structures as jurisdictional product design — one brand, parallel venues, each tuned to the strictest rules it must satisfy locally while serving global volume elsewhere.
- Regulators respond in kind by treating offshore-facing arms of licensed domestic exchanges as part of the same risk perimeter, making cross-border group structure a core supervisory question rather than an edge case.
The trend: Korean crypto exchanges are internationalizing through decentralized and offshore venues to escape domestic regulatory and security constraints, turning jurisdiction itself into product design.
