85% Altcoin Volume Drives Korean Crypto Anomaly

Woofun AI reports that the South Korean cryptocurrency ecosystem operates in stark contrast to global mainstream trends, a structural anomaly detailed in analysis by Heechang Kang, Luffy, and Foresight News. While global markets prioritize Bitcoin, the local landscape is dominated by altcoins, with major platforms Upbit and Bithumb exhibiting trading patterns that diverge significantly from international giants Binance and Coinbase.

The scale of this divergence is quantifiable. During the most recent statistical period, long-tail minor cryptocurrencies accounted for 58% of trading volume on Upbit and 52% on Bithumb. In sharp contrast, Bitcoin constituted only 9% of transactions within the South Korean market. Globally, Bitcoin’s dominance is far more pronounced, representing 23% of volume on Binance and 47% on Coinbase. The South Korean spot market ranks second globally in size, generating an average weekly trading volume of approximately $26 billion, which accounts for 30% of the world’s total spot trading volume. As early as Q1 2024, the quarterly trading volume of Korean won-based pairs reached $456 billion, temporarily surpassing the US dollar to become the top fiat currency in terms of crypto trading volume. Despite this massive capital inflow, only 15% flowed into Bitcoin and Ethereum, while the remaining 85% poured into altcoins and newly launched tokens.

This capital allocation has cemented the dominance of local exchanges. Upbit joined the top five global exchanges by trading volume, initially holding over 80% of the South Korean market share, though this figure later adjusted to 72%. Together, Upbit and Bithumb control nearly 96% of the country’s trading volume. By early 2025, registered users on these platforms exceeded 16.2 million, surpassing the 14.5 million stock market investors in South Korea. Regulatory data indicates that by the end of 2024, 9.7 million traders had completed identity verification, a 25% increase in half a year. The total value of crypto assets held by these users doubled to $77.5 billion, reflecting intense retail participation.

The investor demographic further explains this behavior. The age distribution is concentrated among those aged 30 (29%) and 40 (27%).

Notably, 66% of users hold less than 500,000 Korean won in crypto assets. These small-scale, active retail investors form the core driver of long-tail cryptocurrency trading. While global exchanges focus on BTC and ETH, the South Korean market allocates 85% of its volume to altcoins, with Bitcoin at 9% and ETH at 6%. This preference is not accidental but stems from specific structural constraints.

Structurally, the lack of compliant derivatives forces retail investors to use spot altcoins as 'natural leverage tools.' There are no legal crypto futures, options, or leverage products available in South Korea. Consequently, overseas traders cannot easily profit through derivatives locally. Capital controls further isolate the market; rules requiring real-name registration for local bank accounts and restricting deposits and withdrawals to the Korean won effectively prevent overseas market makers and cross-market arbitrage teams from entering. Market pricing is thus driven entirely by local retail sentiment, without professional institutions to hedge against swings.

Listing limitations exacerbate this concentration. Upbit supports transactions only in Korean won and lists around 324 tokens, whereas Binance and Bitget offer over 700 listed tokens. With the same amount of local capital allocated to fewer assets, each new token receives disproportionate attention. This is compounded by a retail-driven culture where digital products spread rapidly, and trending topics trigger unified buying waves. Unlike the US market, which relies on ETFs and corporate funds to stabilize institutional buying interest, South Korea lacks such stabilizing forces, leading to volatile, retail-dominated price action.

The listing effect on Upbit and Bithumb triggers immediate and sharp price surges. For instance, PRL saw its trading volume surge by 5,500% within 24 hours of listing. SLX’s price doubled, HYPER rose by over 100%, AZTEC increased by 82%, and SKR saw its trading volume soar by 700% with a price increase of 62%. New listings have become a competitive tool; in September 2025, Bithumb’s market share rose to 46%, prompting Upbit to launch seven new tokens within 10 days as a countermove. This creates a closed-loop liquidity mechanism where speculation is intense and immediate.

Speculation follows a rigid daily pattern known as the '9 a.m. trend.' At 9 a.m. South Korean time, obscure altcoins often see collective price surges, driven by coordinated retail trading rather than industry news. Even during platform disruptions, this enthusiasm persists. In November 2025, Upbit suffered a hack that halted withdrawals and deposits, yet investors continued to speculate on tokens like ORCA and RAY. This phenomenon, termed 'fishnet pumping,' generated $340,650 in fees for the platform in a single day. In February 2026, ZKsync surged by nearly 970% during maintenance, triggering regulatory investigations and highlighting the market’s closed-loop nature.

Woofun AI data shows that the 'kimchi premium'—a consistent price difference of 2%-3%—peaked at 10.88% in March 2024.

However, by the end of 2025, this premium turned negative, indicating a shift in market dynamics. The short-term premium effect from new listings has weakened significantly. The lifecycle of new token liquidity is brief; on Upbit, median liquidity loses most of its value within 10–15 weeks. By the 51st week, the median weekly liquidity of surviving tokens remains at $11.3 million, second only to Binance’s $25.6 million, and roughly five times that of Coinbase ($2.3 million) and Bithumb ($2.2 million).

Token retention rates reveal the harsh reality of this model. By the 51st week, only 42.7% of tokens on Upbit and 40.5% on Bithumb maintain a trading volume of over 10% of their initial peak. In comparison, Binance retains 43.6%, and Coinbase achieves a high 63.8%. Tokens on Coinbase tend to have lower initial popularity but more stable trends, aiding retention. In contrast, South Korean tokens experience massive initial volume but suffer rapid decay. Overall, nearly 60% of newly listed tokens in South Korea lose most of their initial capital within a one-year period. This market exhibits a deep but selective memory, where intense elimination occurs in the first few months. A new listing does not guarantee permanent liquidity but rather initiates a one-year selection process, with only a few tokens ultimately achieving stable liquidity levels in the tens of millions.
