DMM Bitcoin Hack: Third-Largest in Crypto History
Japan-based cryptocurrency exchange DMM Bitcoin confirms a devastating security breach on May 31, revealing the loss of 4,502.9 Bitcoin valued at roughly 48.2 billion yen, or $308 million at current prices. The company describes the incident as an “unauthorized leak” involving the transfer of funds from one unknown Bitcoin wallet to another.
The hack ranks as the third-largest cryptocurrency theft in history and the largest since the collapse of FTX in December 2022. Among Japan-based exchanges, it is second only to the infamous Coincheck hack of 2018, which saw the loss of approximately $530 million in NEM tokens.
Security firm Halborn notes that the breach highlights persistent vulnerabilities in exchange custody solutions, particularly around private key management. The incident raises fresh questions about the security posture of mid-sized exchanges operating in regulated markets like Japan, which is generally considered to have robust crypto oversight.
DMM Bitcoin moves quickly to assure customers that all affected users will be fully compensated, pledging to raise the necessary funds to purchase replacement Bitcoin. The exchange promises to maintain normal operations during the recovery process.
Ethereum ETF Race Intensifies
While the DMM Bitcoin hack dominates headlines, the Ethereum ETF pipeline shows significant progress. Six companies file updated S-1 registration statements on May 31, meeting the SEC end-of-month deadline following the regulator approval of 19b-4 filings on May 23.
In a notable development, 21Shares drops Ark Invest from its joint Ethereum ETF filing. The product, previously named the “Ark 21Shares Ethereum ETF,” is rebranded as the “21Shares Core Ethereum ETF.” All references to Ark Invest as a subadvisor are removed from the filing. Ark Invest has not commented on the separation.
Franklin Templeton becomes the first prospective ETH ETF issuer to disclose its sponsor fee, setting it at 0.19%. Bloomberg ETF analyst Eric Balchunas observes that issuers are not engaging in the same aggressive fee war that characterized the spot Bitcoin ETF launches earlier in the year.
Options Expiry Adds Volatility
The May 31 trading session also sees the expiration of approximately 69,000 BTC options and 92,000 ETH options contracts, creating additional market uncertainty. Options expirations of this magnitude typically lead to heightened volatility as traders adjust or close their positions.
With Bitcoin trading around $67,491 and Ethereum near $3,760, market participants watch closely for any significant price movements triggered by the options expiry. The combination of the DMM Bitcoin hack news and large-scale options expirations creates a particularly tense trading environment.
What This Means for Altcoin Markets
The Ethereum ETF narrative continues to buoy altcoin sentiment, with traders speculating that the approval of spot ETH ETFs could open the door for additional altcoin-based investment products. The broader altcoin market holds relatively steady despite the DMM Bitcoin hack, suggesting that institutional momentum around ETF approvals is providing a floor for prices.
Why This Matters
The convergence of a major exchange hack and rapid progress on Ethereum ETF filings captures the dual nature of the crypto market in 2024. While institutional adoption through regulated ETF products accelerates, security vulnerabilities at exchanges remain a persistent threat. The DMM Bitcoin hack serves as a stark reminder that even exchanges operating under Japan stringent regulatory framework are not immune to sophisticated attacks. Meanwhile, the ETH ETF pipeline continues to advance, with all major issuers now having met the SEC filing requirements, bringing the market one step closer to the launch of spot Ethereum ETFs in the United States.

4502 BTC stolen and they call it an unauthorized leak. thats a hack plain and simple. DMM trying to soft peddle the language
Third largest hack ever and it barely made mainstream news. Compare that to the FTX coverage. Shows how desensitized people are to exchange failures in crypto
japan has some of the strictest crypto regulations and this still happened. regulation doesnt prevent hacks, it just changes the headlines afterwards
Franklin Templeton setting a 0.19% fee on the ETH ETF is smart positioning. undercutting everyone else to grab AUM on day one
69000 BTC options expiring the same day as the DMM hack news. talk about a cocktail of volatility
