According to CoinDesk, the Polish prosecutor's office has charged Roman Ż., a former business partner of the missing BitBay/Zondacrypto founder Sylwester Suszek, with two counts, including fraud.Roman Ż. was arrested last Saturday in the Silesia region of Poland, and his lawyer stated that he had assisted in managing the exchange before BitBay was renamed Zonda. Roman Ż. denies the charges and has provided a detailed statement to investigators, with police seizing valuable watches and documents related to Zondacrypto during the search.The prosecutor's office stated that the arrest was ordered due to concerns that Roman Ż. would flee upon learning of plans to travel to China, with his lawyer describing the trip as a business trip and stating that he held a return ticket for September 13. The court will decide whether to continue detaining Roman Ż. during the investigation.Previously, BitBay was renamed Zondacrypto in 2021, and the exchange ceased trading in April, following customer withdrawal freezes, with estimated losses of at least 35 million zlotys (approximately 9.4 million USD). The Estonian Financial Intelligence Unit partially suspended the license of the brand entity BB Trade Estonia OÜ. The Polish prosecutor's office has launched an investigation into suspected large-scale fraud and money laundering, receiving over 3,600 complaints as of June.The case is also related to Suszek's disappearance in March 2022, with the prosecutor's office merging the Zondacrypto investigation with the Suszek missing person case in August.

According to Cointelegraph, the U.S. Attorney's Office for the Southern District of New York urged the court in court documents to dismiss former Celsius CEO Alex Mashinsky's application to overturn his conviction and reduce his sentence, stating that his legal arguments "lack merit." Mashinsky was sentenced to 144 months in prison and fined $48 million for commodity fraud and securities fraud in May 2025.In May, he informed the court that he would represent himself, and the motion submitted involved allegations related to FTX and former colleague Roni Cohen-Pavon, but prosecutors pointed out that he had not submitted a sworn statement to support the allegations and requested the court to dismiss it without a hearing. Cohen-Pavon has completed his sentence for providing "substantial assistance." Additionally, the CFTC permanently banned Mashinsky from engaging in commodity market trading in June, and the SEC's civil lawsuit against him is still ongoing, with both parties in the "settlement discussions" stage.

The indictment lists 504 suspects who are accused of using shell companies, bank accounts, currency exchange offices, POS terminals, and cryptocurrency transactions to conceal illegal proceeds.

According to Protos, prosecutors in Wisconsin and New York have expressed dissatisfaction with the stablecoin issuer Circle, citing that Circle has repeatedly hindered law enforcement's attempts to recover stolen funds. Law enforcement agencies in various locations have sought Circle's cooperation to help victims of fraud and hacking incidents recover losses by destroying and reissuing USDC tokens, but Circle has refused these requests based on policy positions.Circle believes that modifying the blockchain ledger to reverse transactions would undermine the fundamental attributes of the USDC stablecoin and set a dangerous precedent for the entire cryptocurrency industry. This position highlights the deep-seated conflict between the immutability of blockchain and law enforcement needs. Prosecutors argue that Circle, as a regulated stablecoin issuer, should bear more social responsibility, while Circle insists on upholding the core principles of blockchain technology, making it difficult for both sides to bridge their differences on this issue in the short term.

According to a report by the International Consortium of Investigative Journalists (ICIJ), the stablecoin issuer Circle has been criminally charged by the Wisconsin state prosecutor for refusing to comply with a court order to assist in recovering funds for fraud victims.A victim in Wisconsin was defrauded of approximately 381,000 USDC, and the court issued a warrant last December requiring Circle to transfer frozen assets to law enforcement wallets, but Circle refused to comply, citing "technical inability to destroy and reissue tokens."The New York state prosecutor had previously sent a letter to the U.S. Senate, accusing Circle of repeatedly refusing asset freeze requests without a warrant and questioning its motives—Circle currently holds at least 119 million frozen USDC, which can continuously earn interest.In response, Circle denied the allegations, stating that the Wisconsin court lacks jurisdiction, and indicated that it has reached a preliminary agreement with federal prosecutors regarding a compensation mechanism for victims. Cryptocurrency tracking experts pointed out that Circle could fully implement token destruction and reissuance by updating its code, casting doubt on its claim of technical incapacity.

The WeChat public account of the Chinese prosecutor published an article titled "Research on Foreign-Related Cases | Key Points for Cross-Border Electronic Evidence Collection in Virtual Currency Money Laundering Crimes," which pointed out that when handling virtual currency money laundering cases, one should use the virtual currency wallet address as a breakthrough point, apply blockchain technology to analyze on-chain data characteristics and the flow of funds, and identify money laundering activities conducted through virtual currencies to achieve precise strikes.The article proposed that the evidence collection model should be built around two core proof elements: identity relevance and transaction relevance, establishing a "domestic evidence collection as the basis, cross-border evidence collection as a supplement" approach, and standardizing the applicable boundaries of unilateral evidence collection and bilateral judicial assistance to enhance the efficiency of cross-border evidence collection.For third-party entities such as exchanges, wallet service providers, and payment channels, the article suggested establishing "elemental" retrieval standards, focusing on obtaining KYC information and change records, login logs, device and IP information, two-factor authentication records, deposit and withdrawal records, on-chain addresses, transaction hashes, as well as risk control and freezing records, to establish the relationship of "address---account---natural person."

According to Marketscreener, Swedish Economic Crime Authority prosecutor Jonas Myrdal stated that the early leak of news on social platform X regarding Sivers Semiconductors (SIVE) considering a dual listing in the U.S., which was officially confirmed by the company about 48 hours later, is not a coincidence and is highly likely to involve information leakage.Jonas Myrdal pointed out that the relevant information was published and continuously promoted on the X platform by an anonymous account with about 200,000 followers before the official disclosure, which subsequently led to a significant increase in the company's stock price within a short period. This pattern of behavior is similar to a previous case involving "pump-and-dump" manipulation, in which three individuals were convicted of serious market manipulation. He further suggested that the Nasdaq exchange should investigate this incident and assess whether there are violations of the EU Market Abuse Regulation (MAR). Currently, the source of the information leak is still under investigation.Previously, the "new stock god" Serenity posted on the X platform, seemingly "calling" Sivers, and expressed an optimistic outlook after further reviewing the latest earnings call content of Sivers Semiconductors. The company's management stated that "viewing ecological partners as competitors is not the correct mindset in a super cycle where demand far exceeds supply," reflecting the current strong demand in the photonics industry. Additionally, the photonics business pipeline has rapidly grown over the past five months, driving an overall revenue pipeline increase of 77%.

The French National Anti-Organized Crime Prosecutor's Office (Pnaco) has stated that cases of kidnapping and illegal detention involving cryptocurrency are continuing to surge. Among the 12 related cases currently under investigation, 88 people have been prosecuted, including more than 10 minors, and another 75 are in custody awaiting trial.Prosecutor's data shows that since 2023, French law enforcement has recorded 135 such cases, with 18 in 2024, rising to 67 in 2025, and reaching 47 so far in 2026. Many of these cases involve violent kidnappings, ransom extortion, and forcing victims to transfer cryptocurrency assets. The prosecution pointed out that some suspects have appeared multiple times in different cases, indicating the formation of a structured criminal network behind it. The previous kidnapping incident involving Ledger co-founder David Balland is also seen as an important sign of the escalating security risks in the French cryptocurrency industry.

According to Decrypt, the U.S. Attorney's Office for the District of Connecticut announced that it has recovered and seized over $600,000 in cryptocurrency after a Ledger hardware wallet user fell victim to a phishing scam, being lured into performing a so-called security check by a letter impersonating "Ledger Security and Compliance," resulting in approximately $234,000 in crypto assets being stolen.The FBI and state police tracked the flow of funds, successfully seizing about $600,000 in USDT and filing a civil forfeiture lawsuit, alleging that the source of the funds involved wire fraud and money laundering. It is reported that this is one of a series of phishing incidents targeting hardware wallet users, where scammers used physical mail letters featuring company logos, holograms, and QR codes to enhance the credibility of the fraud. Similar incidents have affected companies like Ledger and Trezor, accompanied by data breaches and vulnerabilities in third-party services, leading to ongoing phishing attacks.

According to CoinDesk, federal prosecutors submitted documents to the judge questioning the authenticity of a letter claimed by FTX founder Sam Bankman-Fried to have been sent from prison. Prosecutors pointed out that the letter was actually sent via FedEx from the Palo Alto or Menlo Park area, which does not match the Terminal Island federal prison where he is located, and the letter incorrectly labeled his federal prison as a state facility, using a typed signature instead of a handwritten one, violating the federal prison's prohibition on using private couriers to send mail.Although prosecutors did not directly accuse SBF or his associates of forging documents, they stated that the aforementioned inconsistencies are sufficient to raise reasonable doubts about the letter's origin, which will affect the credibility of related evidence in his motion for reconsideration. SBF is currently serving a 25-year prison sentence for fraud and conspiracy and is actively seeking a reconsideration, but the appellate judges have shown clear skepticism towards his claims.

According to Bloomberg, U.S. prosecutors stated that FTX co-founder Sam Bankman-Fried's request for a retrial should be denied because he failed to prove that his conviction was unjust.SBF is serving a 25-year prison sentence after a jury found him guilty of fraud and conspiracy in connection with the collapse of the FTX cryptocurrency exchange in 2023.

According to Decrypt, federal prosecutors in Massachusetts have filed a civil forfeiture lawsuit seeking to seize approximately $3.4 million in USDT, alleging it is the proceeds of cryptocurrency investment fraud and money laundering.Prosecutors state that victims have been approached since the end of 2024 through methods such as "wrong text messages." After establishing relationships via WhatsApp, Telegram, and other platforms, they were guided to invest in an exclusive Ethereum project purportedly backed by physical gold. In practice, victims were instructed to transfer ETH to an intermediary wallet, which was then converted to USDT and transferred to a non-custodial wallet to conceal the source and ownership of the funds.

According to the U.S. Attorney's Office for the District of Massachusetts, the office has filed a civil forfeiture lawsuit seeking to recover approximately 3.444 million USDT (worth about 3.444 million USD), which are suspected to be proceeds from an online investment fraud and money laundering scheme.The case involves at least four victims, including two residents of Massachusetts, one resident of Utah, and one resident of South Carolina. The scammers established contact with the victims through seemingly misdirected messages sent via SMS or encrypted communication apps like WhatsApp and Telegram, and then lured the victims into investing in a so-called Ethereum investment opportunity backed by physical gold. Victims were instructed to purchase ETH and transfer it to an intermediary wallet controlled by the scammers, who then converted the ETH into USDT and transferred it to an unmanaged wallet to steal the funds.

According to The Block, the Gwangju District Prosecutor's Office in South Korea sold 320.8 bitcoins, with the proceeds of 31.6 billion won (approximately 21.5 million USD) submitted to the national treasury.This batch of bitcoins was originally confiscated after a crackdown on an illegal gambling platform, but was stolen due to a phishing attack on officials, until the hacker voluntarily returned it in February of this year. The prosecution then sold it in batches over 11 days (from February 24 to March 6). The hacker is still at large, and the investigation is ongoing.

According to The Block, the U.S. Attorney's Office in Boston has initiated a civil forfeiture lawsuit seeking to recover approximately 327,829.720952 USDT. These funds are suspected to have originated from a cryptocurrency scam targeting residents of Massachusetts through a dating app.The investigation reveals that the case began in the fall of 2024. Victims met a suspect who claimed to be "Linda Brown" on the dating app and were lured into participating in so-called "cryptocurrency investments" after weeks of communication. The victims sent funds to wallets controlled by the suspect or their accomplices, only realizing they had been scammed when attempts to withdraw failed. Prosecutors stated that the stolen funds were transferred through multiple wallets and exchanged for USDT, ultimately used for money laundering transactions.

The CFTC Chairman has appointed former federal prosecutor and private practice attorney David Miller to lead the agency's enforcement division.David Miller previously served as a litigation partner at Greenberg Traurig and Morgan Lewis, focusing on commodities, securities, digital assets, and national security, and he has also served as an Assistant U.S. Attorney in the Southern District of New York. Michael Selig stated that David Miller will be dedicated to combating fraud, abuse, and manipulation, rather than formulating policy. Currently, Washington lawmakers are pushing to grant the CFTC broader jurisdiction over the cryptocurrency industry.

According to Reuters, the U.S. Commodity Futures Trading Commission (CFTC) announced on Monday that former prosecutor David Miller will become the agency's chief enforcement officer. This move comes as the CFTC is preparing to strengthen its oversight of cryptocurrency and prediction markets.As the new enforcement chief of the CFTC, Miller will be responsible for leading the agency's regulatory enforcement efforts in the digital asset space.

The U.S. Attorney's Office for the Eastern District of North Carolina announced the seizure of over $61 million in USDT. These funds were traced to cryptocurrency addresses associated with "pig butchering" cryptocurrency investment scams.The investigation revealed that criminals often gain victims' trust under the pretense of establishing romantic relationships, then claim to have professional skills in generating high profits through cryptocurrency trading, guiding victims to use fake trading platforms that mimic legitimate ones. These platforms showcase fictitious high-return portfolios to entice victims to increase their investments. When victims attempt to withdraw funds, the scammers further extract money under the pretext of needing to pay "taxes" or "fees."
