With a Market Share of Nearly 70%, How Does Upbit Manage the Wealth Anxiety of Korea's 'Ants'?

Author: Conflux

In South Korea, there is a widely circulated saying: "There are three things that a Korean cannot avoid in life: death, taxes, and chaebols." However, if you shift your focus to the current young people and financial circles in South Korea, this saying might need a fourth word: leveraging to trade stocks.

In July, the South Korean stock market experienced severe fluctuations, directly leading to over 1.2 million retail leveraged accounts hitting the "death margin call line," with hundreds of thousands of young people watching their principal vanish in an instant. In South Korea, this behavior has a specific term—"빚투" (Bit-too, borrowing money to invest). To buy Nvidia, Tesla, or heavily invest in local Samsung Electronics, countless young South Koreans have resorted to extreme measures of "offshore lending + onshore brokerage financing," pushing leverage to its limits.

However, if you think that leveraging to trade stocks is the ceiling of gambling for South Koreans, you are too naive. In South Korea, the madness of the stock market is at best just an appetizer; the real ultimate battlefield that keeps them awake day and night, caught in collective mania, is cryptocurrency.

As a country with a population of just over 50 million, South Korea not only frequently contributes astonishing crypto trading volumes that catch global attention but has also nurtured a truly "giant" level exchange—Upbit.

Today, let's delve into Upbit's dominant position in South Korea and this group of "Korean ants" who are perpetually in FOMO (fear of missing out).

The Absolute Dominance of the Crypto Giant

If you haven't been to South Korea, it's hard to imagine the national popularity of Upbit locally. On the subway in Seoul, in cafes in Gangnam, you can always catch glimpses of the Upbit's iconic red and blue candlestick chart on young people's phone screens (Note: In South Korea, the convention is red for gains and blue for losses).

According to the latest data from mid-2026, among the five major Korean won-compliant exchanges—Upbit, Bithumb, Coinone, Korbit, and Gopax—Upbit's market share is an astonishing 67.4%!

Notably, despite the recent "crypto winter" in the market, Upbit's market share has not only remained stable but has actually increased. In an era where liquidity reigns supreme, there has been a clear "concentration of funds towards the top" effect. The second-ranked exchange, Bithumb, has been trying to fight back with strategies like zero fees, but it only captures about 27.1% of the market. The gap in market share between the two has widened to over 40%.

Why is it Upbit?

• Strong backing and large traffic: Upbit was founded by the well-known South Korean fintech company Dunamu, which early on partnered with the "national-level" chat app KakaoTalk (similar to WeChat in China), reinforcing its brand endorsement in the local market.
• Extremely smooth user experience: Its app's UI design is highly technological and operates smoothly, making it extremely user-friendly for novices.
• Fiat deposits as easy as drinking water: The deep integration with South Korea's pure online bank K-Bank allows retail investors to experience fiat deposits and withdrawals extremely smoothly, creating a strong moat.

Setting aside the "one strong, one weak" pattern between Upbit and Bithumb, the survival status of other exchanges in South Korea is a brutal tale of blood and tears------

The South Korean government implements extremely strict "real-name bank account" regulations on the crypto market, and there are strict limitations on derivative trading such as contract leverage for compliant exchanges. In this "island market" where only spot trading is allowed, liquidity is life. Retail investors instinctively flock to the platforms with the best depth to avoid slippage during trades, leading to a situation where the strong get stronger.

The remaining Coinone, Korbit, and Gopax have long hovered in single digits or even fractions of a percent in market share. Faced with a significant decline in active user ratios in the broader market environment, these smaller platforms have had to struggle to transform: some have started focusing on institutional custom services, some are seeking partnerships with traditional brokerages, and others are undergoing deep internal layoffs and restructuring.

More Than Just a Leader, But an Indicator of Sentiment

The value of Upbit is not just in its large market share, but it almost represents the direction of risk appetite among South Korean retail investors. There is a clear flow of funds between the stock market and the crypto market: when the stock market offers a stronger profit effect, funds will shift towards stocks; when the crypto market heats up again, some funds will flow back to the crypto market.

This means that Upbit is very much like an "emotional amplifier." When market risk appetite rises, its trading volume and attention will rapidly amplify; when sentiment cools, trading volume will quickly drop.

Public reports indicate that when the heat of the South Korean crypto market declined in 2025, Upbit's daily trading volume also saw a significant drop, while at the same time, the activity in the South Korean stock market noticeably increased, with funds migrating from the crypto market to the stock market.

In the short term, Upbit's dominant position is still difficult to shake. As long as South Korean retail investors continue to prefer high-volatility assets, as long as won trading remains the mainstream entry point, and as long as liquidity and compliance advantages remain concentrated on a few platforms, Upbit will continue to be the most important platform in South Korea's crypto market.

However, in the medium to long term, it is not without variables. Regulatory changes, market cycles, and the reallocation of South Korean retail investors between stocks and crypto assets will all affect its trading activity.

In other words, Upbit's future is not determined in isolation, but is highly tied to the overall sentiment of South Korean investors.

Better to Liquidate Than to Work?

Returning to the phenomenon of "빚투" (borrowing money to invest) mentioned at the beginning of the article. Why are young South Koreans so aggressive and full of gambling spirit whether trading U.S. stocks or cryptocurrencies? In the financial context of South Korea, these retail investors are referred to as "ants" (개미), and the ants in the crypto market are the most formidable.

All of this stems from the fact that this generation of young South Koreans faces extremely high youth unemployment rates, an intensely competitive job market (with chaebols monopolizing good jobs), and sky-high housing prices in the Seoul metropolitan area. The traditional East Asian narrative of "work hard - buy a house - get married" has already fractured here.

Since a meager monthly salary can never afford a house, why not borrow some money and dive into the crypto market? For them, high-volatility cryptocurrencies are almost the only "legal lottery" that can achieve class mobility.

Moreover, due to South Korea's strict foreign exchange controls (capital cannot freely enter and exit for arbitrage), combined with the extremely high local enthusiasm for trading cryptocurrencies, the price of Bitcoin on South Korean exchanges often exceeds that on international platforms like Binance and Coinbase by several percentage points or even over 20%. This crazy premium in a closed market is the most direct reflection of the extreme thirst for capital within South Korea.

Getting liquidated in the stock market? No worries, in the crypto market, you don't even need to borrow leverage. Unlike the preference of institutional funds in Europe and the U.S. for Bitcoin (BTC), South Korean ants are particularly fond of low-market-cap, high-volatility altcoins with narrative hype. On Upbit, you often see some obscure altcoin whose daily trading volume directly crushes that of Bitcoin.

In summary, South Korean retail investors are not looking for stable returns of 10% annualized, but rather the extreme thrill of "a big win, either partying with models or diving into work."

Koreans, who rely on iced Americanos to survive, seem to even skip sleep. Even at three in the morning Seoul time, trading on Upbit remains active. In any globally renowned crypto project, you cannot ignore the frenzied calls of the South Korean community.

Conclusion

In South Korea, cryptocurrencies, like leveraged stock trading, have long ceased to be merely financial assets or investment behaviors; they have become a social movement that embodies the despair, anxiety, and desires of young people.

The reason Upbit can crown itself king in this market is not only because it provides the best trading infrastructure but also because it perfectly embodies a whole generation of South Koreans' extreme desire for "getting rich" and "changing their fate."

For global crypto projects, having a KRW trading pair on Upbit remains one of the most valuable pieces of good news in the crypto world. Because it means that your token will directly face the most formidable and reckless "Korean ants" on this planet.

Times are changing, and the regulatory boots of South Korea's crypto market (such as the crypto capital gains tax in 2027) are about to drop, but as long as the anxiety to break the class solidification persists, the red and blue K-lines of South Korea will continue to dance wildly.
