South Korea has emerged as a major player in the global cryptocurrency landscape, thanks to its advanced internet infrastructure and tech-savvy population. With widespread public interest in digital assets, the country hosts a vibrant crypto trading ecosystem powered by several leading exchanges. But when it comes to volume, user base, and market influence, one platform stands out. So, what is the largest cryptocurrency exchange in South Korea, and which other platforms are worth watching?
This guide dives deep into the top South Korean exchanges, spotlighting their key features, trading offerings, and market positions — all while helping you understand the broader regulatory and investment context.
What Is the Largest Cryptocurrency Exchange in South Korea?
The title of South Korea’s largest cryptocurrency exchange goes to Upbit. Operated by Dunamu & Company, Upbit dominates the domestic market with an overwhelming share of daily trading volume. Since its launch in October 2017, it has rapidly expanded its user base and asset offerings, becoming the go-to platform for Korean traders.

Upbit supports over 150 digital assets and enables KRW (South Korean won)-paired trading pairs for popular cryptocurrencies like Bitcoin (BTC), Ethereum (ETH), and many altcoins. Both takers and makers are charged a flat 0.25% trading fee, which remains competitive within the local market.
One of Upbit’s standout advantages is its integration with KakaoTalk, South Korea’s most popular messaging app, through the Kakao Stock platform. This seamless connection allows millions of users to trade cryptocurrencies as effortlessly as sending a message — significantly lowering the barrier to entry for new investors.
Thanks to a strategic partnership with U.S.-based exchange Bittrex, Upbit was able to launch with robust technical infrastructure and a wide range of supported tokens — over 120 at launch. During the 2017 crypto boom, Upbit recorded staggering trading volumes, reaching $4.5 billion in daily volume on average** and peaking at **$11 billion in a single day.
Looking ahead, Upbit aims to shape the future of crypto benchmarking by launching the Upbit Crypto Index (UBCI) — a proposed global index designed to reflect real-time market trends and provide transparency for investors, startups, and regulators alike. If successful, UBCI could become a standard reference point for Initial Coin Offerings (ICOs) and institutional participation in Korea’s evolving blockchain economy.
Major Cryptocurrency Exchanges in South Korea
While Upbit leads the pack, several other exchanges play crucial roles in South Korea’s digital asset ecosystem. Together, these platforms form a highly concentrated market where Upbit and Bithumb alone account for nearly 96% of total trading volume. Here's a breakdown of the most influential exchanges:
1. Upbit
As already discussed, Upbit is the market leader in terms of liquidity, user experience, and security. It leverages years of experience in operating large-scale financial systems to deliver bank-grade protection and smooth trading operations. The exchange conducts rigorous token listing reviews, enhancing trust among retail and institutional users.
2. Bithumb
Founded in 2014, Bithumb ranks as one of South Korea’s oldest and most prominent crypto exchanges. It supports more than 180 digital assets, including major coins like BTC, ETH, XRP, ADA, DOT, and MATIC, across over 280 trading pairs. Bithumb also offers KRW trading pairs and has historically attracted significant trading activity.
Despite facing security challenges in the past — including a notable hack in 2017 — Bithumb has strengthened its cybersecurity protocols and continues to maintain a strong presence. It appeals particularly to experienced traders due to its advanced order types and deep liquidity pools.
3. Coinone
Established in 2014, Coinone holds the position of South Korea’s third-largest exchange. It focuses on providing secure and straightforward trading services for core cryptocurrencies such as Bitcoin and Ethereum. Known for its high-security standards — including cold storage solutions and multi-layer authentication — Coinone prioritizes asset protection against hacking and fraud.
Coinone also launched Coinone Custody, a dedicated institutional-grade wallet service, catering to professional investors and blockchain projects seeking secure long-term storage.
4. Korbit
Launched in 2013, Korbit was one of South Korea’s first cryptocurrency exchanges. It played a pioneering role in introducing Bitcoin to mainstream Korean audiences and continues to offer reliable trading services for BTC, ETH, and other major digital currencies.
Although regulatory changes limited Korbit’s access to foreign customers — particularly those using international bank accounts — it remains a trusted name in the domestic market. The platform emphasizes user-friendly design and educational resources for beginners.
5. Gopax
Founded in 2017, Gopax is a rising player backed by Shinhan Investment Group, part of one of Korea’s largest banking conglomerates. This institutional support gives Gopax a strong credibility edge. The exchange offers KRW trading for major cryptocurrencies like BTC and ETH and employs advanced security measures such as multi-layer encryption and physical air-gapped servers to protect user funds.
Gopax is often seen as a bridge between traditional finance and digital assets, appealing to conservative investors who value compliance and stability.

Regulatory Environment and Market Challenges
South Korea enforces strict regulations on cryptocurrency exchanges to prevent money laundering, ensure investor protection, and promote market integrity. Key requirements include:
- Mandatory real-name bank account verification for all users.
- Exchanges must partner with licensed financial institutions to handle fiat deposits and withdrawals.
- Compliance with Anti-Money Laundering (AML) and Know Your Customer (KYC) standards.
These rules have raised operational costs and reduced liquidity on some platforms, but they’ve also increased public trust in regulated exchanges. However, market volatility remains high, and concerns about price manipulation — especially around "Kimchi premium" events (where crypto prices in Korea temporarily exceed global averages) — persist.
Additionally, while government oversight protects users, it can also slow innovation and limit access for foreign investors or decentralized finance (DeFi) integrations.
Frequently Asked Questions (FAQ)
Q: Is Upbit available outside South Korea?
A: Upbit primarily serves Korean users with KRW trading pairs. While some international versions exist (like Upbit Singapore), they operate under different regulations and may not offer the same range of services.
Q: Can foreigners trade on South Korean crypto exchanges?
A: Most major exchanges require Korean bank accounts linked to real-name verification. This makes it difficult for non-residents to participate directly unless they have legal residency or local banking access.
Q: What is the “Kimchi premium”?
A: The Kimchi premium refers to the phenomenon where cryptocurrency prices on South Korean exchanges trade higher than global averages due to high local demand and capital controls limiting arbitrage.
Q: Are South Korean exchanges safe?
A: Leading platforms like Upbit, Bithumb, and Gopax implement strong security measures. However, past incidents highlight that no system is immune. Always use two-factor authentication and avoid keeping large amounts on any exchange.
Q: Do these exchanges support stablecoins or DeFi?
A: Support is limited compared to global platforms. Regulatory scrutiny restricts widespread stablecoin adoption, though interest in DeFi is growing cautiously among tech-savvy users.
Q: How do I choose the best exchange in South Korea?
A: Consider factors like trading fees, available assets, security features, ease of deposit/withdrawal in KRW, and customer support quality. For most users, Upbit or Bithumb will be the top choices.
