A Seoul-based funeral services company disclosed an unrealized loss of approximately ₩45 billion (~$33 million) tied to a leveraged ether-linked ETF, according to a corporate filing made public on May 20, 2026.
The company, Bumo Sarang (부모사랑, "Parental Love"), holds the T-REX 2X Long BMNR Daily Target ETF (ticker: BMNU), a product managed by Tuttle Capital Management. BMNU is designed to deliver 200% of the daily return of Bitmine Immersion Technologies (BMNR), which describes itself as the world's largest publicly traded holder of ether. The holdings have not been sold; the loss remains unrealized as of the disclosure date.
How a 2x daily ETF works — and why it erodes
BMNU is not a long-term hold vehicle. Like all daily-rebalanced leveraged ETFs, it is built to hit its target multiple for a single trading day, then reset. That daily reset creates compounding drag in volatile markets: a day of 10% loss followed by a day of 10% gain does not return to break-even on a 2x product. Over weeks or months of ETH-related volatility, the structural decay accelerates losses well beyond the underlying asset's move. Tuttle Capital's fund documentation notes the product is intended for short-term trading. A corporate balance sheet is the wrong vehicle for it.
The Korean context
Bumo Sarang's position fits a documented pattern in South Korean retail and corporate markets. South Korea is among the world's most active leveraged and inverse ETF markets by retail participation. Korean regulators flagged amplified-exposure product risks ahead of the 2026 crypto equity wave; Bloomberg covered the structural behavior of Korean retail in leveraged crypto-adjacent instruments in April 2026. This is not the first time Korean corporate buyers have taken significant speculative positions through crypto-related equity products rather than direct holdings.
The mismatch between a funeral services firm's core business and a 2x leveraged bet on ether treasury company equity is stark on paper. It may reflect access: Korean investors face restrictions on directly holding certain crypto assets, but exchange-listed ETFs are reachable through standard brokerage accounts. Leveraged ETFs on crypto-adjacent equities have become a practical, if structurally hazardous, proxy for directional ETH exposure.
What the loss reflects
Bitmine's ether treasury thesis was priced for a sustained ETH rally. ETH's retreat from its 2025-2026 highs, combined with the amplification from daily resetting leverage, produced outsized losses at the BMNU level. The ₩45 billion figure in the disclosure reflects that compounded drawdown on Bumo Sarang's position size.
The filing does not indicate the original cost basis or when the position was established. Without that, the total return on the investment and the exact ETH price at entry cannot be confirmed from the disclosure alone.
