In a damning development for South Korea’s crypto space, Bitsonic CEO fraud has again taken center stage. Shin Jin-wook, the former CEO of the defunct crypto exchange Bitsonic, has received a second prison sentence for a separate instance of fraud involving investor funds and token manipulation.
This new verdict adds to an earlier 7-year sentence handed down in 2024, further solidifying Shin’s place at the heart of one of South Korea’s most high-profile digital asset scandals.
Second Sentence Fuels Public Outcry
The Bitsonic CEO fraud saga intensified on August 5, 2025, as the Seoul District Court convicted Shin of misappropriating over ₩160 million KRW (approximately $115,000 USD). Prosecutors accused him of artificially inflating Bitsonic Coin (BSC) values and siphoning funds for personal investments unrelated to the platform.
Judge Seong Gi-jun commented, “Though the damage was smaller than in the prior case, the defendant’s repeated deception undermines trust in financial markets.” The court gave Shin a 6-month extension to his existing jail term.
Fraud Timeline: A Pattern Emerges
The Bitsonic CEO fraud did not occur in isolation. In 2024, Shin and the exchange’s CTO, surnamed Bae, were convicted of defrauding customers out of 10 billion KRW (~$7.5 million). The manipulation ran from 2019 to 2021 and involved fake trading volumes and misleading token price data.
South Korea’s prosecutors revealed Shin used false announcements and rigged transactions to boost trading interest, enabling the offloading of BSC tokens at inflated prices.

Regulatory Pressure and Industry Reactions
The Bitsonic CEO fraud has reignited debate around South Korea’s crypto regulations. Local lawmakers recently enacted the Virtual Asset User Protection Act, which gives regulators more power to freeze assets, investigate exchanges, and ensure consumer protection.
A crypto policy analyst at SeoulTech, Min Ji-hoon, stated:
“Bitsonic’s case proves why oversight is vital. This isn’t just a black eye, it’s a systemic failure that affects investor confidence in all Korean exchanges.”
Public Trust on the Decline
The broader crypto community in Korea has responded with skepticism. Several investors have voiced frustration over the repeated failures to detect the Bitsonic CEO fraud in its early stages. Many blame poor auditing standards and lack of transparency in smaller exchanges.
One affected investor, Kim Seo-yeon, said:
“It’s devastating to lose your life savings to a platform you trusted. The authorities are late, but at least they’re acting now.”

Conclusion
The Bitsonic CEO fraud scandal highlights the dark underbelly of unregulated or poorly managed crypto exchanges. As Shin Jin-wook faces his second sentence, regulators are moving to tighten legal frameworks.
This case could serve as a landmark precedent for future fraud prosecutions in the digital asset sector. For now, though, South Korean investors are left with damaged trust, and hopes for stricter enforcement going forward.
