Cango, Inc., a Shanghai-headquartered Bitcoin mining business which is publicly listed on the New York Stock Exchange (NYSE: CANG), provided a mining operations update on Aug. 5, disclosing a significant increase in its crypto production.Photo by Dmytro Demidko on Unsplash45% increase in outputThe update outlined that in June, the firm mined 450 BTC, while holding 3,879.2 BTC, with a deployed hashrate of 32 EH/s. The figures for July show a considerable uptick, with 650.5 BTC having been mined. That Bitcoin was retained, bringing the firm’s overall Bitcoin treasury holding to 4,529.7 BTC, with a deployed hashrate of 50 EH/s. Cango CEO Paul Yu outlined that the firm had added 18 EH/s in hashpower towards the end of June. This additional capacity accounted for the increased output experienced for the month of July, representing a 45% increase month-on-month. Yu stated: “This strong performance not only demonstrates our commitment to execution but also fuels our ambition to accelerate future production.” The Cango CEO added that a new and experienced management team is now in place, and with that, Cango is focusing on working towards transitioning to “a more diversified and resilient portfolio of mining sites and energy infrastructure." Cango isn’t the only company in the Bitcoin mining sector to up its production. Cipher Mining, an American miner with facilities in Texas, also published an update, indicating that it produced 214 BTC in July with a hashrate of around 20.4 EH/s, up 21.43% month-on-month. Cipher outlined that Black Pearl Phase I, the initial 150 MW tranche of its Black Pearl facility, came on stream last month, accounting for the increased output. Unlike Cango, Cipher sold 52 BTC as part of what it described as “its regular treasury management process.” In this respect, Cango bucked a trend in comparison with its industry peers. CryptoQuant reported that miners became significant sellers of Bitcoin in July, depositing 16,000 BTC to exchanges as of July 18.Ranked by BitcoinTreasuries.net in order of Bitcoin held, Cango now holds 18th place among corporations holding BTC.Originally an automotive transaction service platform operating within the Chinese market, Cango announced a new departure last November, with the signing of agreements to buy $400 million in crypto mining equipment from a number of vendors, including Bitmain. With crypto mining a banned activity in China, the company has deployed its mining operations at various locations across North America, South America, the Middle East and East Africa. By January, the company was being referred to as a “Bitcoin mining powerhouse.” At that time, the company’s Communications Director, Juliet Ye, told CoinDesk that the firm’s entry into the Bitcoin mining sector had surprised people, given that “nobody has ever heard of Cango before.” By April, Cango had sold its legacy auto-financing business for $352 million to a firm linked to Bitmain affiliate, Antalpha, allowing it to focus exclusively on mining. The company’s stock has surged 180% over the course of the last 12 months. Ye said that the Chinese firm’s pivot to Bitcoin mining has created a buzz around the company that had been absent previously.

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.
