South Korea has emerged as one of the most active retail cryptocurrency markets globally. According to data from the Korea Financial Intelligence Unit (KoFIU), an estimated 6 million South Koreans—over 10% of the population—were actively investing in digital assets by mid-2023. This significant adoption rate highlights a deeply embedded culture of crypto trading, primarily centered around domestic centralized exchanges (CEXs) such as Upbit, Bithumb, Coinone, and Korbit.
This article dives into the unique characteristics of South Korea’s crypto ecosystem, analyzing trading behaviors, exchange dominance, investor preferences, and regional market dynamics—all based on recent transactional data and market trends.
📉 Overall Trading Volume Declines, but Korean Exchanges Gain Market Share
While global crypto trading volumes have cooled since their peak in early 2023, South Korean exchanges have defied the downward trend by increasing their relative influence.
- Global slowdown: After reaching a high point in March 2023, CEX trading volumes declined due to reduced market volatility. Bitcoin remained range-bound between $27,000 and $28,000 for six consecutive months.
- Korean rebound: Despite a sharp drop from $45 billion in February to $23 billion in May, Korean exchange volumes recovered strongly—surpassing $37 billion in July. This growth outpaced even Binance during the same period.
- Rising global footprint: The combined trading volume of South Korea’s top four exchanges now represents around 10% of Binance’s volume, exceeding that of Coinbase. More notably, their market share relative to Binance grew from 7% in March to 16% in September, signaling increased domestic exchange strength.

🔝 Upbit Dominates with Over 80% Market Share
Upbit stands as the undisputed leader in South Korea’s crypto landscape.
- Market control: In February 2023, Upbit recorded $36 billion in trading volume—accounting for nearly 80% of total domestic exchange activity. Even after a brief dip to 70% in August, it quickly rebounded, maintaining consistent dominance.
Competitor landscape:
- Bithumb: Holds second place with 15–20% market share.
- Coinone: Commands only 3–5%.
- Korbit: Trails behind with less than 1%.
- News-driven spikes: Korean exchanges showed strong sensitivity to market news. For example, following Ripple’s partial legal victory over the SEC in July—causing XRP to surge 80%—the four major Korean exchanges saw trading volume jump from $27 billion to $37 billion month-on-month, a 37% increase.
This responsiveness underscores how local investor sentiment can rapidly shift based on regulatory or project-specific developments.
💸 Bithumb’s Zero-Fee Strategy: Short-Term Boost, Long-Term Questions
In October 2023, Bithumb launched a bold experiment: zero trading fees.
- Initial success: The policy led to a temporary surge in trading volume and pushed Bithumb’s market share above 20%.
- Fading impact: However, the effect was short-lived. Within weeks, activity reverted to pre-policy levels.
- Sustainability concerns: Eliminating fees removes a core revenue stream for exchanges. While it may attract users temporarily, long-term viability remains uncertain—especially when other factors like security, liquidity, and product offerings also influence user choice.
This outcome suggests that South Korean traders value more than just cost savings—they prioritize platform reliability and access to niche assets.
🆚 Upbit vs. Coinbase: Contrasting Investment Cultures
A comparison between Upbit and Coinbase reveals stark differences in investor behavior across regions.
| Aspect | Upbit (South Korea) | Coinbase (U.S.) |
|---|---|---|
| Primary Focus | Altcoins ("shitcoins") | Bitcoin & Ethereum |
| Investor Base | Retail-dominated | Institution-heavy (~85%) |
| Risk Appetite | High – chasing quick gains | Lower – focused on stability |
Upbit users show a clear preference for high-risk, high-reward altcoins, often driven by speculation rather than fundamentals. In contrast, Coinbase’s institutional clients favor large-cap assets like BTC and ETH for portfolio stability.
This divergence reflects broader cultural and structural differences: while U.S. markets are increasingly institutionalized, South Korea remains a stronghold for passionate retail participation.
🔍 What Coins Do Korean Investors Love?
Analysis of trading activity during the third week of October revealed which cryptocurrencies were most actively traded on Korean exchanges compared to global markets:
- Loom Network (LOOM): 62% of its total trading volume occurred in Korea
- eCash (XEC): 55%
- Flow (FLOW): 43%
- Stacks (STX): 37%
- Bitcoin SV (BSV): 34%
These figures highlight a strong regional bias toward lesser-known or under-the-radar projects.
The LOOM Surge: Mystery Behind the Rally
In mid-September, LOOM began a meteoric rise—from less than 70 KRW to a peak of 686 KRW within a month, entering the top 100 by market cap. There was no official announcement or partnership to explain the rally. By mid-October, however, prices crashed back down to ~140 KRW.
Such extreme volatility is not uncommon in Korea’s speculative market environment.
The “Gaduri” Effect: How Deposit/Withdrawal Policies Impact Prices
One unique phenomenon observed in the Korean market is the “Gaduri” effect (a colloquial term meaning "trapped money").
When FLOW suspended deposits and withdrawals on October 14, its price and trading volume spiked despite no global news. Why?
Because when funds cannot be moved between exchanges, arbitrage opportunities vanish—leading to localized price inflation on Korean platforms. This isolation effect amplifies volatility and creates temporary bubbles.
🧠 Deep Dive: Why Upbit Is Unique
Upbit hosts several cryptocurrencies that are almost exclusively traded within South Korea—dubbed "Kimchi coins" or "泡菜幣".
Examples include:
- Steem Dollars ($SBD)
- Moss Coin ($MOC)
- Hippocrat ($HPO)
- Sentinel Protocol ($UPP)
These tokens have 100% of their global trading volume on Upbit, indicating closed-loop ecosystems driven by domestic demand.
Conversely, major global cryptos like BTC, ETH, and MATIC see relatively low trading activity on Upbit compared to their worldwide volumes—further evidence of divergent investment priorities.

🌐 Network Preferences: Why Tron Dominates Over Ethereum
When depositing or withdrawing funds, Upbit users show a strong preference for the Tron (TRON) network over Ethereum.
- Tron handles 5x more transactions per week than Ethereum on Upbit.
- Lower fees and faster settlement make Tron ideal for frequent transfers.
- Daily USDT transactions on Tron exceed 2 million, versus ~100,000 on Ethereum (per CoinMetrics).
This trend suggests that many Korean investors use crypto not for DeFi or dApps—but primarily for moving capital between exchanges.
It also implies that South Korean CEXs may lack advanced financial products (like futures or margin trading), pushing users to offshore platforms via low-cost networks like Tron.
❓ Frequently Asked Questions (FAQ)
Q1: Why do so many Koreans trade cryptocurrency?
South Korea has a highly tech-literate population with widespread internet access and a cultural affinity for speculative investing. Add supportive infrastructure (like real-name banking integration) and high smartphone penetration, and you get fertile ground for crypto adoption.
Q2: What are "Kimchi coins"?
"Kimchi coins" refer to cryptocurrencies listed mainly or exclusively on South Korean exchanges. They often lack significant international traction but thrive due to localized hype and limited supply.
Q3: Is there a "Kimchi premium"?
Yes—the "Kimchi premium" refers to higher crypto prices on Korean exchanges compared to global markets, caused by capital controls and high local demand. However, it has narrowed in recent years due to improved cross-border arbitrage tools.
Q4: Why do Korean traders favor altcoins?
Retail investors in Korea tend to seek high-return opportunities quickly. With limited exposure to traditional venture capital or private equity, altcoins offer accessible speculative plays—even if they carry substantial risk.
Q5: Are Korean exchanges safe?
Most major platforms comply with strict AML/KYC regulations set by KoFIU. Upbit and Bithumb require real-name bank accounts for deposits/withdrawals, enhancing accountability and reducing fraud risks.
Q6: How does regulation affect crypto trading in Korea?
South Korea enforces rigorous compliance standards. While this increases trust, it also limits innovation—such as staking services or anonymous wallets—pushing some users toward offshore platforms.
✅ Final Thoughts: A Market Built on Retail Energy
South Korea’s crypto market is defined by passionate retail participation, exchange concentration (especially Upbit), altcoin enthusiasm, and unique local phenomena like the Gaduri effect and Kimchi coins.
For global projects aiming to expand into Asia, understanding these regional nuances is critical. One-size-fits-all marketing strategies won’t work—success requires tailored approaches that speak directly to Korean investor psychology and platform behaviors.
