A South Korean funeral services company has reported an unrealized loss of approximately 49.3 billion won ($32.7-35.6 million) tied to investments in leveraged ether exchange-traded funds. According to reports, the Seoul-based Bumo Sarang, Korean for Parental Love, invested 59.5 billion won in the T-REX 2X Long BMNR Daily Target ETF (BMNU), a leveraged exchange-traded fund managed by Tuttle Capital Management. The ETF seeks to deliver 200% of the daily performance of Bitmine Immersion Technologies (BMNR), the world's largest publicly traded holder of ether. By the end of 2025, the investment's book value had fallen to 10.2 billion won, leaving Bumo Sarang with the substantial paper loss. A company spokesperson described the hit as a 'short-term unrealized loss due to global market volatility' and said it was 'sufficiently controllable within the company's financial buffer.'
The investment in the T-REX 2X Long BMNR Daily Target ETF represents a high-risk leveraged trading strategy that amplifies both gains and losses. As reported, leveraged ETFs are designed for short-term trading and can magnify both positive and negative market movements, making them among the riskiest exchange-traded products available to retail investors. The BMNU ETF's 2x leverage and daily reset mechanism particularly worsened losses as Bitmine's stock remained volatile. The company's losses remain unrealized, meaning the holdings have not yet been sold, though the disclosure highlights the growing appetite in South Korea for speculative, crypto-linked investment products.
Bitmine Immersion Technologies has been an eye-catching name for crypto-focused investors, with the company recently adding 71,672 ETH in a single week, bringing its holdings to about 5.28 million ETH — roughly 4.37% of total Ethereum supply. As of May 17, the company valued its ETH stash at $2,191 per ETH and said it was about 87% of the way to its target of holding 5% of Ethereum's circulating supply. Bitmine's share price fluctuations have been closely linked to Ethereum sentiment and demand for on-chain treasuries, making it a favorite among local buyers trading overseas equities.
The disclosure underscores the growing appetite in South Korea for speculative, crypto-linked investment products, particularly leveraged ETFs tied to digital asset firms and related equities. According to reports, South Korea has become one of the world's busiest markets for leveraged and inverse ETF trading, with regulators warning investors about volatility and the risks associated with amplified exposure products. The losses also reflect recent sharp swings in crypto-related equities as digital asset markets remain highly volatile. The episode has reignited concerns about how South Korea's funeral mutual-aid firms handle prepaid customer funds, as these organizations collect money from customers long before services are needed but are overseen by the Fair Trade Commission rather than financial regulators.
A Korea Economic Daily review of 2025 audit reports from 75 funeral service companies found that 32 firms (42.7%) held total assets smaller than the prepaid balances they owe customers, a situation that could create refund pressures if many clients ask for returns at once. The paper also flagged Christian Funeral Family of Faith (Mideumui Gajok) as reporting a 500 million won net loss in 2025, underscoring broader financial strain among smaller operators. The case highlights how crypto-linked losses can arise outside exchanges and wallets, bleeding into real-world businesses and consumer protections. It is likely to intensify debates over whether prepaid customer funds should be allowed in high-risk investments and whether tighter oversight is needed for non-financial firms that handle funds on behalf of consumers.
