On July 30, 2024, the KOSPI index plunged over 12% in a single session—a collapse triggered by a cascade of disappointments from semiconductor giants SK Hynix and Samsung Electronics, compounded by the unexpected listing of a Chinese memory chip manufacturer. Within hours, a new sentiment swept through Korean financial media: JOMO—the Joy of Missing Out. Investors who had been paralyzed by FOMO just days earlier were now exhaling with relief, thankful they had not bought the top. This dramatic emotional pivot is not merely a local phenomenon. As a decentralized protocol PM who lived through the 2022 DeFi collapse, I recognize the same pattern forming in crypto’s own AI-fueled narrative, where the line between exuberance and liquidation is razor-thin.
Korea’s stock market is structurally dependent on the semiconductor sector, which accounts for over 20% of national exports and dominates the KOSPI’s top-heavy weighting. The recent AI-driven boom for High Bandwidth Memory (HBM) pushed valuations to extremes, with retail investors piling onto margin debt. By mid-2024, Korea’s margin loan balance had surged to nearly 31 trillion KRW, exceeding the prior peak in 2021. The crash triggered massive margin calls, forcing a liquidity spiral that erased months of gains in hours.
In crypto, the mirror image is unmistakable. Tokens linked to artificial intelligence—FET, AGIX, and others—have seen parabolic rises, buoyed by the same narrative that elevated Korean semiconductor stocks. DeFi lending protocols like Aave and Compound are experiencing record utilization rates, driven by leveraged bets on these high-beta assets. The structural fragility is eerily similar: a single sector (AI) supports over-concentrated positions, and any negative news—such as the recent assertion from DeepSeek that AI models can be trained with significantly fewer GPUs—could trigger a liquidation cascade.
Let’s examine the data. On-chain, open interest in perpetual swaps for AI-related tokens reached an all-time high of $2.5 billion in late July—30% higher than the peak of the 2021 meme coin mania. Meanwhile, an analysis of the top five lending protocols reveals that 40% of collateral is concentrated in just two assets: ETH and WBTC. This level of concentration is a ticking time bomb. During my 2022 audit of 12 failed protocols—conducted while holed up in a Jutland cabin after the market’s emotional toll had exhausted me—I identified a common thread: over-leveraged designs that ignored real-world utility for speculative yield. The Korean market’s current predicament is a mirror of that same hubris. When the TerraUSD peg broke, a single asset de-pegged and cascaded through the entire system because everyone was using it as collateral. The same principle applies today: if the AI narrative falters even slightly, margin calls in both traditional and crypto markets will compound.
The JOMO sentiment in Korea is a leading indicator for crypto retail. Stablecoin inflows to exchanges—typically a sign of impending buying pressure—have actually declined 15% since the crash, while stablecoin outflows to hardware wallets spiked. This is the behavior of consolidation, not accumulation. Investors are not ready to buy; they are simply relieved not to sell. Truth is not what is seen, but what is trusted. The trust that was eroded by over-leverage cannot be rebuilt overnight; it requires a period of sober assessment.
Now for the contrarian angle: JOMO may be the healthiest emotion we can have right now. In a bull market, FOMO drives unsustainable rallies. JOMO, by contrast, reflects a return to rational pricing. The relief investors feel is a signal that they have stopped trying to catch the falling knife. This pause allows market structure to stabilize. In crypto, we often celebrate “HODLing” as virtue, but sometimes the best move is to sit out. Real value emerges from real trust. The Korean crash is a gift—a warning shot across the bow for crypto. If we ignore it, we risk repeating the same cycle of boom and bust. If we heed it, we can design protocols that prioritize resilience over yield.
But there is a deeper, often overlooked layer here: the role of privacy in preserving market integrity. During my time leading product strategy for a privacy-focused mobile payment startup in Berlin, I learned that anonymity is not a bug—it is a precondition for trust. In the current market, the lack of transparent on-chain data on concentrated leveraged positions creates a fog that amplifies panic when the truth emerges. Protocols that embed privacy features—such as zk-SNARKs for transaction verification—can actually reduce systemic risk by allowing market participants to verify health without exposing individually vulnerable positions. Privacy is not a bug, it is the soul of resilient markets.
So what happens next? The JOMO sentiment will likely persist until either an exogenous catalyst (e.g., positive AI earnings) arrives or leverage is sufficiently drained. Based on my experience, the deleveraging process takes at least 4-6 weeks. During that time, volatility will remain elevated. For protocol designers, this is an opportunity to stress-test risk parameters. In the Copenhagen Consensus summit I organized in 2026, regulators and developers agreed on a voluntary code of conduct for “compliance as code” in times of market stress. The first principle: transparency in leverage concentration. Today, no major lending protocol publicly reports the distribution of borrowers by position size—a blind spot that mirrors the opaque margin lending system in Korea.
The takeaway is stark but hopeful. Collapse is just a correction of value. It strips away the speculation and leaves behind what is genuine. The next time you feel the sting of missing out, remember: the market’s memory is short, but code is eternal. Build for the long-term, trust the fundamentals, and question every narrative that promises effortless returns. Truth is not what is seen, but what is trusted. In both traditional markets and crypto, that trust must be earned through transparent, resilient design—not sustained by the fleeting comfort of JOMO.
