3AC-founded OPNX Exchange announces closure

Do Kwon, a South Korean national and the central figure in the 2022 collapse of the Terra blockchain ecosystem, was sentenced to 15 years in prison on Dec. 11, capping a federal case that exposed a multibillion-dollar scheme built on false promises and secret market manipulation. According to a U.S. Department of Justice press release, District Judge Paul A. Engelmayer handed down the sentence in Manhattan federal court, finding that the 34-year-old orchestrated a scheme that inflicted substantial losses on both retail and institutional investors.Photo by Tingey Injury Law Firm on Unsplash"This was a fraud on an epic, generational scale. In the history of federal prosecutions, there are few frauds that have caused as much harm as you have, Mr. Kwon," Engelmayer said, according to Reuters. Kwon, who was extradited to the U.S. in December 2024 following his arrest in Montenegro, pleaded guilty in August. Addressing the court, he acknowledged the devastation caused by the collapse. "All of their stories were harrowing and reminded me again of the great losses that I’ve caused. I want to tell these victims that I am sorry," Kwon said. A house of cardsAccording to court filings, Kwon’s deception ran from 2018 through 2022, misleading investors regarding the stability of the algorithmic stablecoin TerraUSD (UST), the LUNA token, and the independence of the Luna Foundation Guard. Prosecutors outlined a pattern of fabrication across Terraform’s products. When UST lost its $1 peg in May 2021, Kwon claimed an automated "Terra Protocol" restored balance. In reality, investigators found the company secretly utilized a high-frequency trading firm to prop up the price, creating a "false impression" of the system’s resilience. The fraud extended to Terraform’s partnerships and applications. Investigators said Kwon lied about the South Korean payments platform Chai, claiming its transactions were settled on the Terra blockchain. Instead, Chai used traditional payment networks, with Terraform simply copying data to the blockchain to feign integration. Similarly, Kwon allegedly manipulated the Mirror Protocol, a platform for synthetic stock trading. While touting it as decentralized, prosecutors said he used bots, funded by stablecoins he created, to inflate volume and manipulate asset prices. The collapse and captureBy spring 2022, the ecosystem’s value exceeded $50 billion. However, when UST broke its peg again in May 2022, Terraform could not artificially restore it. The resulting crash erased at least $40 billion in value and triggered a contagion across digital-asset markets. While Kwon publicly claimed cooperation with authorities during the fallout, prosecutors introduced recordings suggesting he privately explored seeking political protection to avoid accountability. He was eventually arrested in Montenegro in March 2023 for traveling on a fraudulent passport. In addition to the prison term, Judge Engelmayer ordered Kwon to forfeit over $19 million, including interests in Terraform and its digital assets. The case was investigated by the Federal Bureau of Investigation (FBI) with assistance from Montenegrin and South Korean authorities. The Securities and Exchange Commission (SEC) has filed a separate civil action. Global crackdown widensWhile the U.S. concludes the Kwon case, scrutiny of the crypto sector is intensifying abroad. DL News, citing the Belarusian outlet Onliner, reported that Belarusian authorities have blocked access to digital asset trading platforms Bybit, Bitget, and OKX. The Ministry of Information cited the Mass Media Act for the decision, though KuCoin and Binance remain accessible. The step contrasts with President Alexander Lukashenko’s earlier support for developing a national crypto reserve and mining sector. Meanwhile, the Belarusian arm of Russia’s Sputnik reported that State Control Committee chairman Vasily Gerasimov recently put in place a record system identifying wallets authorities suspect are used for criminal money laundering. 

SBI Zodia Custody is discontinuing operations two years after its launch, Bloomberg reported. The joint venture was formed by Tokyo-based SBI Holdings and Zodia Custody, an institutional digital-asset platform backed by Standard Chartered, with ownership split 51% and 49% respectively.Photo by Haotian Zheng on UnsplashStrategic realignment behind exitAccording to people at the companies involved, the decision reflected shifting priorities at both partners. Zodia Custody chief executive Julian Sawyer described the move as a mutual alignment of strategy and said the company had prepared materials to seek local registration with Japan’s Financial Services Agency but had not filed an application before opting to exit. An SBI Holdings spokesperson said the dissolution did not signal a withdrawal from crypto custody or the company’s broader Asia strategy, describing the step instead as an effort to generate greater collective impact across SBI’s digital ecosystem. Security breaches shape regulatory climateThe retreat comes as overseas crypto businesses continue to face a cautious regulatory environment in Japan, a market shaped by several high-profile security breaches. Industry analyses have repeatedly noted that three of the largest crypto hacks targeted Japanese exchanges: Mt. Gox in 2014, Coincheck in 2018, and DMM Bitcoin in 2024. Mt. Gox lost about 850,000 BTC, now worth roughly $98 billion, and began making creditor repayments in July 2024 after years of legal proceedings. The repayment deadline was later extended to Oct. 31, 2025, and initial distributions totaled about 59,000 BTC, or just over 41% of the roughly 141,686 BTC earmarked for repayment, to an estimated 127,000 creditors. Coincheck’s 2018 breach involved what was then about $534 million in NEM tokens. Despite that episode, the company secured approval from the U.S. Securities and Exchange Commission (SEC) in November 2024 for a Nasdaq debut through a merger with Thunder Bridge. The transaction generated roughly $31.6 million in gross proceeds for the combined company. Moving forward, Coincheck is entering Europe through the acquisition of Aplo, a French-licensed digital asset brokerage. The most recent breach involved DMM Bitcoin, which had suspended operations after a May 2024 theft of more than 4,502.9 BTC. Its accounts and assets were transferred in March 2025 to SBI VC Trade, a cryptocurrency exchange owned by SBI Holdings, which said it would support 14 tokens previously listed on DMM that were not available on its own platform. Policy uncertainty as leadership shiftsAt the policy level, uncertainty is growing over Japan’s stance on crypto and blockchain following Prime Minister Shigeru Ishiba’s Sept. 7 announcement that he will step down. Ishiba, who took office in October 2024, has advocated for digital assets, with his latest remarks delivered at the WebX2025 event. There, he pledged greater state support for Web3 initiatives, describing the sector as a driver of innovation that could help address demographic decline and support broader economic change. Last month, Finance Minister Katsunobu Katō, seen as a potential contender to succeed Ishiba, said cryptocurrency could play a role in a diversified investment portfolio, noting its growing user base in Japan. While recent surveys show Sanae Takaichi and Shinjiro Koizumi as the leading preferences for the next Liberal Democratic Party leader, Katō has emphasized the need to foster a stable trading environment for digital asset stakeholders, balancing investor protection with industry innovation. Within this policy climate, SBI Zodia Custody’s shutdown underscores the operational and licensing challenges facing foreign-linked crypto ventures in Japan. 

South Korea is set to allow initial coin offerings (ICOs) next year, easing a ban on crypto fundraising that has been in place since 2017. A draft of the Digital Asset Basic Act, prepared by the Financial Services Commission, would allow domestic sales of digital assets if issuers meet disclosure requirements, the Maeil Business Newspaper reported. The measure is intended to address concerns about tokens that are initially listed on overseas exchanges before becoming available to South Korean investors. The legislation outlines tougher accountability standards for crypto issuers. Projects that provide false information or fail to disclose material details in their whitepapers ahead of an ICO could be held liable for investor losses. Liability would also extend to other parties substantially involved in an offering, including outsourced operators and market makers.Photo by Y K on UnsplashStablecoin issuers need Korean presenceSeparate provisions set out rules for stablecoins, barring tokens issued by entities without a physical presence in South Korea from domestic trading, a restriction that would apply to widely used stablecoins such as USDT and USDC. Issuers would be required to fully back stablecoins with reserves such as cash or government bonds held at banks or financial institutions and would be prohibited from paying interest to users. The proposal reflected the FSC’s position on the second phase of digital asset legislation focused on stablecoin issuers. The issue remains subject to inter-institutional debate, with the Bank of Korea pressing for a bank-led consortium model for stablecoin issuance. The ruling Democratic Party of Korea (DPK) is expected to review a consolidated bill combining proposals from the government and the National Assembly next month, with plans to advance the legislation during the regular parliamentary session in the first quarter of 2026. The FSC’s focus on consumer protection is also reflected in its plans to introduce a Digital Finance Security Act, detailed in a recent report to the presidential office. According to Digital Asset, the proposed legislation would establish rules for traditional financial institutions as well as electronic financial businesses and virtual asset service providers. The move came after a 44.5 billion won ($30 million) hacking incident last month at Upbit, the country’s largest crypto exchange. Existing regulations under the Virtual Asset User Protection Act do not contain provisions specifically covering such cases. Separately, the FSC is working to strengthen its response to emerging forms of financial crime, including transnational offenses and crypto-enabled money laundering. It said measures under consideration included adding state-level criminal organizations to the list of entities barred from financial transactions, improving anti-money-laundering (AML) rules to better align with international standards, and expanding the scope of the travel rule. On the supervisory side, the commission intends to make the Virtual Asset Division a permanent unit after initially establishing it as a temporary body, News1 reported. The Virtual Asset Inspection Division within the Financial Intelligence Unit is also set to become a standing unit. Price declines weigh on exchangesThe stepped-up regulatory focus has coincided with a broader downturn in the crypto market. Bitcoin is trading below $89,000, about 30% below its all-time high of $126,000 set earlier in October. CoinGecko data cited by IT Chosun showed average daily trading volume across South Korean exchanges falling to $2.95 billion in November from $4.41 billion in August, with trading fees accounting for about 98% of exchange revenue. The broader market weakness has also been accompanied by declines in altcoins. South Korean crypto investors attributed the recent drop in altcoin prices to capital flowing into major cryptocurrencies such as Bitcoin and Ethereum. A weekly survey conducted by CoinNess and Cratos showed that 41.7% of the 2,000 respondents cited capital concentration in leading tokens as the primary factor, followed by the growing number of altcoins at 31.6%, their limited practical value at 14.7%, and technical factors such as chart patterns at 12.1%.
