Przemysław Kral, the head of the Polish cryptocurrency exchange Zondacrypto, is reportedly facing criminal charges for involvement in a large-scale fraud and has begun cooperating with Polish prosecutors. According to Polish media Onet, Kral is seeking a reduced sentence in exchange for testimony, which may involve Zondacrypto's funding of right-wing political figures.Prosecutors estimate that Zondacrypto customers have lost at least 2.4 billion Polish złoty (approximately 650 million USD). Investigators claim that the exchange only used a portion of customer funds to purchase cryptocurrencies, while the remaining funds were transferred to private accounts controlled by Zondacrypto's management. Kral has remained silent on X since mid-April when he publicly disclosed that Zondacrypto could not access a cold wallet holding approximately 4,500 bitcoins. He denies misappropriating funds, stating that the private keys for the wallet were supposed to be handed over by Zonda's founder and former CEO Sylwester Suszek, who has been missing since 2022.Reports also state that Zondacrypto was a major sponsor of the Polish CPAC conference, which took place before the second round of the presidential election, ultimately won by Karol Nawrocki. The exchange spent 37 million złoty on advertising with the broadcasting station Telewizja Republika in the last year, while Kral's company also made payments to foundations associated with politicians Zbigniew Ziobro and Przemysław Wipler.

According to Caixin, the Hong Kong police responded to the abnormal liquidation case of Star Bridge Capital's gold trading, stating that multiple reports have been received, with the reported amount of funds that could not be retrieved totaling approximately HKD 6.63 million.

According to Caixin, the Hong Kong Court of Appeal yesterday rejected the sentence reduction application of the mastermind behind the electric fraud and human trafficking, Ma Zhihao, and upheld the original sentence of 56 months in prison. During the investigation of the case, the Hong Kong police tracked the criminal funds through blockchain and cryptocurrency transaction records, identifying the key points where ransoms and criminal proceeds were received.It is reported that a victim's family paid approximately 9,527 Tether (USDT) to a cryptocurrency wallet designated by the criminals. The blockchain tracking records conclusively prove that 8,127 USDT flowed into an exchange account registered under Ma Zhihao's real name and Hong Kong ID, which was then exchanged for about 63,000 Hong Kong dollars and transferred to his personal HSBC bank account, becoming important evidence of his involvement in the crime and obtaining profits. The Court of Appeal pointed out that if it were not for the 7-year sentencing cap imposed by the District Court, the punishment faced by the defendant would be much heavier than this.

The Shanghai Intermediate People's Court has published typical cases, analyzing whether "traffic personnel" involved in telecommunications network fraud related to virtual currencies constitute accomplices in fraud. From February 2022 to April 2023, the defendants, for the purpose of profit, assisted upstream fraudulent activities by "draining traffic," using online virtual phone software to lure victims into related scam groups, ultimately causing 30 victims to be defrauded of more than 2.34 million yuan (the same currency hereafter) by an overseas fraudulent organization. The overseas fraudulent organization transferred funds into the suspects' trading accounts via virtual currency.The Shanghai First Intermediate People's Court pointed out that in telecommunications network fraud cases, "traffic personnel" may constitute accomplices in fraud or illegal use of information networks depending on specific circumstances. The key lies in determining whether they have formed a clear criminal intent connection with the upstream fraudulent organization and whether there is stable cooperation and division of labor. In judicial practice, when assessing the criminal responsibility of "traffic personnel," factors such as their role in the criminal chain, the degree of organizational management, connections with upstream criminals, methods of profit, and abnormal behavior should be comprehensively considered. Actions that only provide general online services and do not form a conspiracy to commit fraud should be distinguished from "draining" actions that knowingly participate in the implementation of fraud.

According to Cointelegraph, Edward Zimbardi, the mastermind suspected of orchestrating a $165 million cryptocurrency Ponzi scheme, was recently deported back to the United States by Fijian authorities after hiding in Fiji for over a year, coordinated by the FBI and the U.S. State Department. He will appear in federal court in the Northern District of Georgia.Prosecutors allege that from June 2022 to August 2023, he promised investors a fixed return of 25% per month under the name "The Crypto Program," illegally raising over $165 million in cryptocurrency assets. The funds raised were not used for the promised advertising package business but were instead diverted to over $34 million in high-risk foreign exchange trading, repaying early investors with new funds, and at least $10 million in personal expenses, including the purchase of real estate, luxury vehicles, and alimony payments. Zimbardi currently faces 12 counts of wire fraud, 12 counts of money laundering, and 1 count of conspiracy to commit money laundering, totaling 25 federal charges.

Tether CEO Paolo Ardoino, in an interview with The Block, responded to ongoing criticisms raised after KPMG U.S. completed its first full financial audit. He stated that some critics are unable to admit that their past judgments about Tether were wrong, and said, "Honestly, I don't care." Ardoino mentioned that Tether has repeatedly proven its resilience.He noted that in 2022, Tether processed $7 billion in redemptions within 48 hours, which was about 10% of its reserves at the time, and there was no pause in redemptions during that period. He believes that many traditional financial institutions would struggle to handle withdrawals of a similar scale in such a short time. He also stated that criticism itself is not a bad thing, as it makes Tether better and stronger. Even if some critics view it as a "villain," as long as Tether can continue to serve its claimed 650 million users who rely on USDT, especially in emerging markets, he does not mind.According to informed sources, Tether, as a private company, will not publicly share audited financial statements. The company plans to conduct a full audit once a year in the future while continuing to release quarterly attestation reports. Overall, the KPMG audit is an important step for Tether to enhance transparency, but controversies surrounding its reserves, disclosure levels, and systemic impact have not completely dissipated.

A man in Anshun, Guizhou, used the name of a virtual currency airdrop project as a pretext to lure friends into investing with the bait of guaranteed high returns, ultimately crossing the legal red line. The People's Procuratorate of Pingba District, Anshun City, Guizhou Province, filed a public prosecution, and the court sentenced Zhao to seven months in prison for fraud, along with a fine of 5,000 yuan.Zhao had been paying attention to the field of virtual currency investment for many years and had long been posting investment insights and financial management tips on social media platforms. Zhang was also a virtual currency enthusiast, and the two met on a social platform due to their common interests, gradually becoming friends and frequently discussing investment strategies online. Through long-term communication, Zhao gained Zhang's trust with seemingly professional investment analysis. Subsequently, Zhao proposed a joint investment, to which Zhang agreed. However, after a period of investment, Zhang experienced significant losses and expressed his intention to stop further investments.On August 23, 2025, Zhao claimed that a certain app had launched an airdrop project (to promote a new project, encourage user participation, or reward loyal users, distributing native tokens of the project for free to eligible users), persuading Zhang to invest the remaining funds in his account into this project, promising a return of 100 to 200 U coins (virtual currency) within two days. Zhao also guaranteed that if there were any losses during this period, he would bear the responsibility. To further alleviate Zhang's concerns, Zhao claimed that all investment funds would be transferred to a public chain (the public address of the virtual currency). Believing Zhao, Zhang exchanged 1,757 dollars in his account for Ethereum and completed the transfer according to the wallet link provided by Zhao. In reality, the wallet corresponding to that link was a personal account registered using his girlfriend's identity information, not a public chain. The agreed time for the return of funds had passed, but Zhao had not fulfilled his promise. Zhang urged for repayment multiple times, but Zhao evaded responsibility with excuses such as sending the wrong link and needing time to track it down. On September 7 of the same year, Zhang reported the situation to the police after noticing something was wrong.On April 2 of this year, the Pingba District Procuratorate filed a public prosecution against Zhao for suspected fraud. The procuratorial agency believed that Zhao deceived others out of property by concealing the truth, with a significant amount involved, constituting the crime of fraud. Given that Zhao truthfully confessed to the criminal facts after being apprehended, showed signs of remorse, and had fully compensated the victim for their losses while voluntarily admitting guilt, he could be punished leniently according to the law.

According to ChosunBiz, Samsung Electronics' System LSI Division has introduced Anthropic's AI programming tool Claude Code for semiconductor design and verification work, with some task cycles shortened to less than one-tenth of the original time. In the verification of data connection structures for customer-customized SoCs, work that was originally expected to take over a month was completed in two days; an engineer with two years of experience completed USB device model development and Android driver adaptation in one day using Claude Code, whereas similar work typically required a month.Samsung opened Claude Code to software developers in May this year and later expanded it to the semiconductor professional development field. The System LSI Division has about 6,000 employees, while its main competitor Qualcomm has about 52,000 employees. Samsung is trying to bridge the manpower gap with AI tools. Meanwhile, Samsung's DS Division is promoting an "AI transformation," extending generative AI from research and development to the entire business process, including production, marketing, and support. The report also pointed out that Claude has exhibited behavior in some verification tasks where it disguised erroneous information as ordinary messages or modified design code without authorization. Samsung emphasized the need for strict control and manual review of the scope and results of AI tasks.

According to Qilu Evening News, a new type of virtual currency "staking mining" scam has recently emerged. Scammers create a perfect persona through long-term friendships on social platforms, chatting with victims for one to two months to build trust. They then guide victims to switch to overseas private communication software such as WhatsApp and Discord, inducing them to download fake mining platforms and sign contracts for authorization. Using the asset transfer permissions from the contracts, they quietly transfer funds from the victims' accounts in the background.The scammers never mention sensitive words like "investment" or "financial management," packaging the scam as "idle computing power staking mining," claiming zero risk and stable returns, and using small rebates to entice victims to increase their investments. Currently, most victims are young people with side job needs, with known losses exceeding 3 million yuan, and the highest individual loss exceeding 300,000 yuan. Victims are spread across many regions of the country. Lawyers remind that virtual currency transactions are not protected by law, and any strangers on social platforms inducing a switch to overseas software or requesting wallet authorization for unfamiliar contracts should be regarded as scams. Do not make secondary transfers.
