In a landmark legal victory for Coinone, one of South Korea's leading cryptocurrency exchanges, the Seoul Western District Court ruled in favor of the platform, ordering five customers to return Bitcoin they had withdrawn twice due to a system glitch. The court's decision, delivered by its second civil division, concludes a years-long legal battle stemming from a 2018 software error that enabled users to exploit what the court termed "unjust enrichment."
The Glitch and Its Consequences
In 2018, Coinone’s systems erroneously interpreted slow Bitcoin network confirmations as failed transactions, triggering automatic account replenishments even after initial withdrawals were successfully processed. Traders capitalized on this flaw, withdrawing the same Bitcoin twice—effectively duplicating their holdings. At the time, the Bitcoin network was severely congested due to soaring transaction volumes following the Bitcoin Cash (BCH) hard fork, with average fees spiking to $55 and over 250,000 unconfirmed transactions pending.
A lower court initially held Coinone partially liable, citing inadequate server systems, and required the exchange to share financial responsibility. However, the appeals court reclassified the network delays as external factors, absolving Coinone of fault and compelling users to repay the duplicated funds.
Legal and Market Ramifications
Key Takeaways:
- Precedent Setting: The ruling establishes a critical legal benchmark for cryptocurrency disputes in South Korea.
- Exchange Accountability: Highlights the need for robust technical infrastructures and clear regulatory frameworks.
- Industry Impact: Reinforces the importance of risk mitigation for crypto platforms globally.
Jung Soo-kyung, a Seoul-based blockchain legal analyst, noted:
"This case underscores the necessity for resilient systems and precise regulations in the crypto sector. As exchanges evolve, so must governance."
Coinone faced prior controversies, including a 2023 scandal involving employees accused of accepting $1.46 million for token listings. Despite these setbacks, this court win may restore stakeholder confidence.
Broader Crypto Community Reactions
The verdict sparks debates on:
- Technical Failures: How exchanges manage unforeseen glitches.

Industry Responses:

Future Outlook
Kim Hye-jin, a blockchain strategist, observed:
"Each ruling like this clarifies the crypto ‘Wild West,’ mapping a more structured future."
Next Steps for Coinone and the Industry:
- Infrastructure Investments: Strengthening systems against technical failures.
- Regulatory Collaboration: Working with policymakers to refine crypto laws.
