Korea Is Now the World's Second Largest Crypto Market — And It's Almost All Altcoins

South Korea has quietly become the second largest fiat-to-crypto market in the world, with won-denominated trades accounting for 30% of all global spot cryptocurrency volume so far in 2026, trailing only the US dollar market, according to research firm Kaiko. A country of just 52 million people is generating approximately $26 billion in weekly crypto turnover, concentrated almost entirely on two domestic exchanges — Upbit and Bithumb. What makes Korea's market particularly distinctive is what its participants are buying: roughly 85% of weekly trading volume flows into altcoins rather than Bitcoin, reflecting a retail-driven appetite for high-volatility assets that stands in sharp contrast to more institutionally oriented markets elsewhere.

For context, Japan's yen-denominated crypto market runs at just $2 to $3 billion monthly across four venues — smaller in volume but with significantly deeper order books, with Tokyo-based Bitflyer holding around $3.5 million in market depth compared to Upbit's $1 to $1.2 million.For traders and investors, Korea's dominance in altcoin volume is a signal worth incorporating into how you think about price movements in smaller tokens. When Korean retail sentiment turns risk-on, the velocity and concentration of that capital flowing into altcoins can move markets in ways that are disproportionate to Korea's overall size. The country's crypto boom is also running alongside a 37% year-to-date rally in Korean equities through early 2026, fueled by AI chip demand — suggesting that the same macro tailwind driving institutional equity positioning is also feeding retail risk appetite in crypto. As long as the AI infrastructure buildout continues to generate economic momentum in Korea through Samsung and SK Hynix, the won is likely to retain its position as the world's second most active crypto currency well into the rest of 2026.
