South Korean Retail Capital Piled Into Ethereum Treasury Stocks and the Losses Are Now Spreading Beyond Individual Investors

[kevin1]

The Bumo Sarang situation is a consequence of a broader trend that saw significant South Korean retail capital rotate into Ethereum treasury companies during 2025. Samson Mow, CEO of Bitcoin technology company JAN3, estimated in an October 2025 X post that approximately $6 billion in Korean retail capital was propping up Ethereum treasury companies, adding that many of those retail buyers did not fully understand the risks they were taking on. The enthusiasm for ETH-linked stocks reflected the same dynamic seen in South Korea's historically high retail participation in speculative asset classes, with investors drawn to the leverage and upside potential of treasury company stocks during a period when Ethereum was still near its highs.

The unwinding of that enthusiasm in 2026 has produced losses that extend beyond individual retail portfolios into institutional and even quasi-public contexts. A funeral company using customer prepaid funds to invest in a 2x leveraged ETH product represents an extreme version of that risk-seeking behavior, but it sits within a wider pattern of South Korean capital reaching for yield and growth through ETH-linked vehicles without fully pricing in the downside scenarios. Bitmine chairman Tom Lee's description of Ether's drop below $2,200 as an attractive buying opportunity reflects one perspective on the current situation, and Bitmine itself has continued accumulating ETH aggressively through the drawdown. Whether that conviction proves well-founded will determine not just the trajectory of dedicated ETH treasury companies but the financial health of the South Korean investors and institutions that bet on them during the cycle's peak.
