For years, South Korea was the global heartbeat of crypto speculation. It became the place where digital coins traded at a premium, and where retail investors flocked to the market overnight. “Kimchi premium” became shorthand for a national obsession: uncontrolled and frenetic trading activity unmatched by any region worldwide.
But by the end of 2025, the story had reversed. The same traders who once looked for the next altcoin gem on Upbit are now glued to the Korean Stock Exchange ticker, swapping meme tokens for memory chips and high-bandwidth semiconductors. Crypto charts have gone quiet – and a new speculation engine has taken their place.
a market became silent
Upbit, once the undisputed center of the Korean crypto craze, now trades at a fraction of its former speed. Average daily volume is down nearly 80% from a year ago, falling from nearly $9 billion at the end of 2024 to just $1.8 billion by November 2025. Bithumb, Korea’s second-largest exchange, has suffered similar losses, losing more than two-thirds of its liquidity over the same period, Woo Blockchain reports.
What was once a nightly national pastime, the endless churn of small-cap coins and chatroom rumors, has vanished. Even instability has collapsed. Where daily volume once fluctuated wildly between $5 billion and $27 billion, the 2025 trading band has shrunk to a slower range of $2 to $4 billion.
Data from analytics provider Dune shows the decline in activity has widened compared to 2018, when Korean exchanges facilitated 280,000 deposits per day at the peak of the frenzy; The daily figure has not exceeded 50,000 since 2021.
The rise of a new passion
The void left by crypto didn’t last long. Retail investors simply moved to a different table – the Korean stock market, which has staged one of the most explosive rallies in its history.
The KOSPI index is up more than 70% year to date, setting multiple record highs. In October alone, it recorded its strongest monthly gain since 2001, climbing 21% and setting 17 new intraday records. The frenzy has been led by AI-linked giants like Samsung Electronics and SK Hynix, whose combined daily trading now accounts for more than a quarter of the entire exchange.
In a country that once treated crypto trading as a kind of collective hobby, the psychology sounds familiar. That same spirit of retail speculation has reemerged, only this time it’s wearing the suit of semiconductor stocks. The number of active trading accounts in the country rose from 86.57 million at year-end to 95.33 million as of Oct. 31, data reported by The Korea Times showed.
Retail enthusiasm spills over into equities
Unlike the meme-driven altcoin rallies of yesteryear, Korea’s equity boom has a more solid backbone. AI is the global growth story of the decade, and Korea controls one of its most important supply chains.
As Nvidia and AMD meet most of the world’s demand for AI hardware, Korean companies like SK Hynix and Samsung have become indispensable. His dominance in high-bandwidth memory (HBM), a key component of AI training, has made him a national champion.
Add to this a government keen to revive domestic markets, and you get what some analysts call a “policy-supported bullishness”. The administration of President Yoon Suk Yeol has pursued reforms to reduce the long-standing “Korea discount”, promoting higher dividends, strict governance and incentives for retail and institutional investment domestically.
Same feeling, different casino
Speculation in the Korean crypto community was never about moderation; It was about rhythm and pace. That hasn’t changed. Margin lending is booming again, leveraged ETFs are taking off and retail participation has doubled in just a year. Leveraged retail positions now account for about 30% of total holdings, according to Bloomberg data, with young traders at the forefront.
In other words, the shift from crypto to equities is not a withdrawal, it is a reallocation of risk appetite. Koreans have not given up speculation; They’ve just found a place where leverage feels legitimate and patriotic.
But this change will also have consequences. Without Korean retail as a liquidity anchor, global crypto markets have lost one of their most frequent buyers. The memecoin rallies that once lit up Korean chatrooms have faded rapidly. And the broader market in general needs a spark; Bitcoin is currently trading around $100,000 despite hitting all-time highs a month ago, while many altcoins have declined more than 20% in the past month.
waiting for the next spark
Crypto’s “kimchi traders” may have gone away, but history suggests they won’t be gone forever. When AI trading cools off, which analysts are suggesting may be on the near horizon, or when the next major crypto story arrives, those same traders may return armed with fresh capital and sharper reflexes.
For now, Korea’s retailers have swapped blockchain for circuit boards, chasing the same rush in a different sector.
