The South Korean cryptocurrency market stands out as one of the most dynamic and unique in the world. With an estimated 6 million crypto investors—over 10% of the national population—Korea plays a pivotal role in shaping regional and global digital asset trends. Unlike more institutionalized markets such as the U.S., Korea's crypto landscape is largely driven by retail investors who heavily rely on centralized exchanges (CEXs) like Upbit, Bithumb, Coinone, and Korbit.
This analysis dives into the structure, behavior, and preferences of Korean crypto investors, focusing on trading volume trends, exchange dominance, investor psychology, and network usage patterns—all crucial for understanding regional market dynamics.
Rising Influence of Korean Exchanges Amid Global Slowdown
While global centralized exchange trading volumes peaked in March and have since trended downward, Korean exchanges have bucked the broader trend. Despite reduced market volatility—Bitcoin remained relatively stable between $27,000 and $28,000 from April to September—Korean trading activity has shown resilience.
After peaking at $45 billion in February**, total monthly volume dropped sharply to **$23 billion in May, but rebounded strongly to $37 billion by July. Notably, this recovery outpaced even Binance, the world’s largest crypto exchange.

When compared to Binance, Korea’s top four exchanges collectively maintained around 10% of its trading volume throughout the year—a significant share. More telling is their growing relative influence: their volume ratio against Binance increased from 7% in March to 16% in September, signaling a strengthening domestic ecosystem.
Upbit’s Overwhelming Market Dominance
Upbit remains the undisputed leader in South Korea’s crypto space. In February 2025, it recorded a staggering $36 billion in monthly trading volume, capturing approximately 80% of the domestic CEX market. Even during a brief dip to 70% in August, its dominance rebounded quickly, reclaiming the 80% mark the following month.
This level of concentration highlights both the maturity and centralization of Korea’s crypto infrastructure.
- Bithumb: A distant second, holding 15–20% of total exchange volume.
- Coinone: Commands only 3–5%, serving a niche audience.
- Korbit: Holds less than 1%, reflecting limited competitive reach.
Such market asymmetry underscores that most Korean investors funnel through just one or two platforms, making exchange-specific policies and listings highly influential on asset performance.
Bithumb’s Zero-Fee Experiment: Short-Lived Boost
In early October, Bithumb launched a bold strategy—zero trading fees—aimed at capturing market share from Upbit. The move initially succeeded: trading volume surged, and Bithumb briefly exceeded 20% market share.
However, the effect was short-lived. Within weeks, volumes reverted to pre-policy levels.
This suggests that while cost matters, Korean investors prioritize trust, liquidity, and platform stability over temporary fee reductions. Moreover, eliminating fees—a core revenue stream—raises sustainability concerns for exchanges in the long run.
Coinbase vs. Upbit: Institutional vs. Retail Focus
A key differentiator between global and Korean markets lies in investor composition.
- On Coinbase, institutional investors account for about 85% of total trading volume (per Q2 shareholder letter). These players favor large-cap assets like Bitcoin (BTC) and Ethereum (ETH) for portfolio stability.
- In contrast, Upbit is overwhelmingly retail-driven. While BTC and ETH exist on the platform, they represent a small fraction of overall trading volume.
Instead, Upbit users show strong appetite for high-risk, high-reward altcoins—many of which are rarely traded outside Korea. This preference fuels a vibrant domestic "altcoin culture" and explains why speculative tokens often see outsized price movements in Korea.
What Koreans Are Trading: The Rise of “Korean Favorites”
An analysis of the most actively traded cryptos on Korean exchanges during mid-October reveals clear patterns:
- LOOM: 62% higher trading volume than global average
- XEC: +55%
- FLOW: +43%
- STX (Stacks): +37%
- BSV: +34%
Notably, temporary spikes occurred when certain tokens faced deposit/withdrawal suspensions. For example, FLOW saw increased trading volume on October 14 despite halted withdrawals—likely due to restricted arbitrage opportunities with overseas exchanges.
Yet some assets maintain consistent popularity regardless of events:
- Stacks (STX)
- eCash (XEC)
These coins remain actively traded on Korean platforms independent of global trends, indicating deep local interest and community support.
Inside Upbit: The “Korean-Only” Token Ecosystem
Upbit hosts several tokens that are virtually exclusive to its ecosystem:
- Steem Dollars ($SBD)
- Moss Coin ($MOC)
- Hippocrat ($HPO)
These assets account for 100% of global trading volume—because they’re only listed on Upbit. Others like Sentinel Protocol ($UPP)**, **Aha Token ($AHT), and Groestlcoin ($GRS) also trade predominantly there.
Collectively known as "Kimchi coins," these tokens form a self-contained market driven by domestic speculation and limited external exposure.
Interestingly, major global cryptocurrencies like BTC, ETH, and MATIC have surprisingly low trading volumes on Upbit compared to platforms like Binance. This divergence reflects distinct investor priorities: Koreans aren’t chasing blue-chip assets—they’re hunting for asymmetric returns in lesser-known projects.

Network Preferences: Why Tron Dominates Over Ethereum
When depositing or withdrawing assets, Upbit users show a clear preference for network efficiency.
Data from the past week shows that Tron (TRON) handles five times more transactions than Ethereum for USDT transfers on Upbit.
Why?
- Lower fees: TRON’s average transaction cost is negligible compared to Ethereum’s often high gas fees.
- Faster processing: Ideal for quick fund movement.
- High throughput: Coinmetrics reports over 2 million daily USDT transfers on TRON, versus ~100,000 on Ethereum.
This trend reveals something deeper: Korean investors primarily use blockchains not for DeFi or smart contracts—but for efficient cross-exchange fund transfers.
Many seek access to services unavailable on local platforms—such as futures trading or USD-based stablecoin pairs—and thus move funds to offshore exchanges. Once there, they may withdraw via blockchain rather than traditional banking rails.
Two structural gaps drive this behavior:
- Limited stablecoin settlement options in Korean won (KRW).
- Lack of diverse withdrawal networks on domestic exchanges.
As a result, users opt for fast, low-cost chains like Tron to bridge Korean and international markets.

Frequently Asked Questions (FAQ)
Why do Koreans trade so many obscure altcoins?
Korean retail investors are highly speculative and respond strongly to social sentiment, influencer trends, and perceived "undervalued" opportunities. Limited access to leveraged products pushes them toward high-volatility altcoins for amplified returns.
What is the “Kimchi premium”?
It refers to the price difference of cryptocurrencies—especially Bitcoin—between Korean exchanges and global markets. Due to capital controls and high local demand, prices in Korea can run 5–15% higher, creating arbitrage opportunities (though riskier now due to tighter regulations).
Are Korean exchanges safe?
Major platforms like Upbit and Bithumb implement strict KYC, cold storage, and insurance mechanisms. However, regulatory scrutiny remains high, and users should still practice due diligence when depositing funds.
Can foreigners use Korean crypto exchanges?
Yes, but with limitations. Most require local bank accounts tied to Korean ID numbers. Some allow limited access via international KYC, but full functionality typically requires residency.
Why doesn’t Ethereum dominate for transfers?
Despite its robust ecosystem and high TVL, Ethereum’s high fees and slower confirmations make it impractical for frequent small transfers. For simple value movement—not DeFi interaction—Tron offers superior UX for retail users.
How might regulation affect Korea’s crypto market?
South Korea has introduced strict AML rules via the Travel Rule and real-name account requirements. Future legislation may further limit leverage or speculative trading, potentially cooling retail enthusiasm unless innovation shifts toward compliant products.
Final Thoughts: A Market That Defies Global Norms
The Korean crypto market is a fascinating case study in regional divergence. With retail-driven altcoin mania, exchange centralization, and distinct blockchain preferences, it operates under its own logic.
Global projects aiming to enter Korea must recognize these nuances: success here doesn’t come from mimicking Western strategies but from building localized engagement—from listing on Upbit to understanding what makes a "Kimchi coin" go viral.
As borders blur in the digital asset economy, Korea proves that local behaviors still shape global price action—one Tron-powered transfer at a time.
