In a significant development for Japan’s cryptocurrency landscape, DMM Bitcoin announced it raised approximately 55 billion JPY (about $365.1 million USD) in June through a series of strategic financing initiatives. Despite this substantial capital injection, the exchange confirmed it will cease operations following the completion of a planned asset transfer to SBI VC Trade, a move stemming from the aftermath of a major security breach earlier in the year.
This article explores the timeline of DMM Bitcoin’s fundraising efforts, the impact of the May 2024 hack, and the transition plan for users and assets. We’ll also examine what this means for Japan’s regulated crypto ecosystem and how affected customers can prepare during this critical period.
Timeline of DMM Bitcoin’s June Fundraising Efforts
DMM Bitcoin executed three distinct funding rounds within a single week in June, demonstrating an urgent push to stabilize its financial position amid growing operational challenges.
- June 3: The company secured a short-term loan of 5 billion JPY (~$33.2 million USD). This initial borrowing likely served as emergency liquidity to maintain platform operations.
- June 7: In a more substantial move, DMM Bitcoin completed a capital increase, raising 48 billion JPY (~$318.6 million USD). This equity-based financing suggests investor confidence—or contractual obligations—from parent or affiliated entities.
- June 10: An additional 2 billion JPY (~$13.3 million USD) was obtained through subordinated debt financing, finalizing the total raise at 55 billion JPY.

While the funds were successfully acquired, they were not enough to reverse the long-term viability of the exchange following a devastating cyberattack just one month prior.
The May 2024 Hack: A Turning Point
In late May 2024, DMM Bitcoin suffered a catastrophic security breach in which hackers stole 4,502.9 BTC, valued at approximately 48.2 billion JPY ($305 million USD) at the time. The incident severely undermined user trust and triggered immediate regulatory scrutiny.
As a result:
- Trading services were suspended or heavily restricted.
- Withdrawals became limited or non-functional.
- Internal audits revealed systemic vulnerabilities in cold wallet management.
Despite initial statements suggesting a potential restructuring and relaunch, DMM Bitcoin ultimately concluded that resuming full operations was not feasible. The decision to wind down services reflects both technical limitations and compliance pressures under Japan’s strict Financial Services Agency (FSA) regulations.
Transition Plan: Asset Transfer to SBI VC Trade
To protect customer interests, DMM Bitcoin entered into an agreement with SBI VC Trade, a licensed crypto exchange under the SBI Group, one of Japan’s most influential financial conglomerates.
Key aspects of the transition include:
- Asset Migration: All customer-held digital assets are expected to be transferred to SBI VC Trade by March 2025.
- Supported Cryptocurrencies: SBI VC Trade will support spot trading for 14 cryptocurrencies previously listed on DMM Bitcoin.
- User Onboarding: Affected users will receive direct communication with instructions on account migration, identity verification, and fund access.
SBI VC Trade emphasized that it would begin processing these assets before the full transfer is complete, minimizing downtime for traders and investors.
What This Means for Japanese Crypto Regulation
Japan has long been at the forefront of establishing clear regulatory frameworks for digital assets. The DMM Bitcoin case highlights several ongoing themes:
- Security as a Compliance Requirement: Exchanges must demonstrate robust cybersecurity measures or risk losing their operating licenses.
- Customer Protection Mechanisms: The swift coordination between DMM Bitcoin and SBI VC Trade shows progress in industry-wide protocols for crisis response.
- Consolidation Trend: Smaller or compromised exchanges are increasingly being absorbed by larger, better-capitalized firms—a trend likely to continue in 2025.
This incident reinforces why regulatory compliance and institutional-grade custody solutions are now central to sustainable crypto business models in Japan.

The Broader Impact on Investor Confidence
The collapse of DMM Bitcoin serves as a cautionary tale for investors and operators alike. Even well-funded platforms can fail if security is compromised. It underscores the importance of:
- Choosing exchanges with transparent security practices.

Final Thoughts
The story of DMM Bitcoin—from raising $365 million to announcing shutdown—is a complex narrative of resilience, regulatory pressure, and technological vulnerability. While the outcome is unfortunate for users, the structured transfer plan led by SBI VC Trade offers a model for responsible crisis management in the digital asset space.
As Japan continues refining its approach to crypto regulation, incidents like this will shape future policies focused on preemptive risk mitigation rather than reactive intervention.
For affected users, staying informed through official channels and acting promptly on migration instructions will be key to preserving asset value and ensuring a smooth transition into the next phase of Japan’s evolving cryptocurrency ecosystem.
