Bitmain Pays Employees Following Salary Suspension

In a major crackdown, the Chengdu Public Security Bureau announced on May 15 the dismantling of an extensive underground banking network, resulting in the arrest of 193 suspects across China in an operation that unveiled illegal businesses using the U.S. dollar stablecoin, Tether (USDT).Photo by DrawKit Illustrations on UnsplashUnauthorized foreign exchange settlements These activities involved illicit transactions amounting to approximately 13.8 billion yuan ($1.9 billion). The investigation began in November 2022 when authorities detected suspicious activities involving underground banks in Chengdu’s Longquanyi district. In response, a specialized task force was formed, integrating experts from various police departments, including economic investigation, cyber security and legal affairs. This team uncovered unauthorized foreign exchange settlements that bypassed national regulations. On June 1 of last year, acting on instructions received from the Ministry of Public Security, the task force conducted coordinated raids in several major cities, such as Shanghai and Shenzhen. These efforts led to the capture of key figures in the criminal syndicate, involving the arrest of 25 suspects. Law enforcement seized numerous bank cards, payment instructions and other digital payment instruments tied to the illegal operations during these raids. A broader investigation across 26 provinces has resulted in 193 suspects being arrested. Using USDT to evade regulationFurther investigations revealed that since January 2021, the syndicate exploited its import and export business to facilitate illegal activities. By using USDT as a medium, they bypassed official foreign exchange channels to service clients needing to transfer funds internationally. Moreover, these operations were intricately linked to other illicit activities, including financial fraud and smuggling. In a related development, on May 13, BeInCrypto reported that the Chinese government arrested six individuals responsible for illicit crypto transactions worth $295 million. These arrests highlight the challenges and risks associated with cryptocurrency in unregulated environments. Additionally, the Hong Kong police recently apprehended three men at a currency exchange shop following a deceptive transaction involving Tether’s USDT. The suspects allegedly showed a customer ceremonial "hell money" before deceitfully persuading him to transfer about $128,073 worth of USDT, only to refuse the agreed-upon cash exchange afterward.  According to the South China Morning Post (SCMP), hell banknotes are a form of ceremonial paper money burned as an offering to ancestors or deities in traditional Chinese culture. Late last year, USDT was used by a gang of gold smugglers in Nepal, who received $16 million in the Tether stablecoin in exchange for the precious metal. A joint investigation carried out by the authorities in Nepal and China led to the arrest of two Chinese and 13 Nepalese nationals in connection with the illicit activity. Over the course of the weekend, it emerged that two Chinese nationals had been charged by the authorities in the United States with money laundering through Bahamas-based Deltec Bank. Deltec acts as the primary banker for Tether, prompting longstanding Tether critics to suggest illicit activity relative to the stablecoin issuer’s dealings with the bank. This series of arrests and discoveries underscores the ongoing efforts of Chinese authorities to clamp down on illegal cryptocurrency activities. The activity also poses problems for Tether in its efforts to maintain compliance and stamp out illicit use in the face of ever-increasing regulatory scrutiny worldwide.

Dunamu, the operator of South Korea’s leading crypto exchange Upbit, announced today that it launched a new crypto price tracking service, Bitcoin-Ethereum Duo Index (Duo Index). The news was reported by the local media outlet Etoday.  The service tracks the two most prominent tokens, Bitcoin and Ethereum, each being the top performer and the runner-up in terms of market capitalization in the crypto asset market. It is a strategy index that equally weights Bitcoin and Ethereum, with their holding ratio updated to 1:1 every month. The weightings of the two cryptocurrencies in the index are subject to an adjustment factor, which is based on their prices. The BTC-ETC Duo Index is currently available on the Upbit Cryptocurrency Index (UBCI) website. Photo by Markus Winkler on UnsplashThe Federal Reserve’s approval of spot Bitcoin ETFs in January has drawn significant attention from many investors, driving up the prices not only of Bitcoin but also Ethereum. Dunamu explained that this heightened interest surrounding Bitcoin and Ethereum is the reason behind its launch of the Duo Index. New tool to boost crypto portfolio’s performance Referencing the Duo Index can help investors estimate their own crypto assets portfolios and boost their performances based on the indicators it offers, including the winning rate of the two coins combined.   The current winning rate of the Duo Index stands at over 58%, which is three percentage points higher than that of the Upbit Market Index (UBMI), which tracks not only Bitcoin and Ethereum but also other altcoins. The high winning rate of the Duo Index demonstrates the bullish sentiment surrounding the two top coins. A Dunamu official stated that the company will continue to keep up with the crypto market trend and further release other strategy indices that would serve the emerging needs of the investors.  

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.
