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.

The Ukrainian police and the Security Service of Ukraine (SBU) recently dismantled a scam network that used a fake investment platform to steal cryptocurrency. This network disguised itself as an investment platform website, luring users to connect their main cryptocurrency wallets and approve a small test transaction when withdrawing funds. Subsequently, it used a "wallet stealer" hidden within the website to automatically transfer user funds to wallets controlled by the operators, kicking victims off the platform. Investigators have currently confirmed 62 victims, with over 46 Ukrainian citizens involved, and the network could steal up to $1 million per month.The police stated that the false profits displayed on the platform are part of the scam, with operators manually creating transactions and adjusting user account balances to create the illusion of investment growth. In addition to cryptocurrency, the platform also collected victims' passport information, phone numbers, email addresses, login credentials, and photos during the registration and identity verification process. The main organizer of the network is a 25-year-old IT expert who recruited over 46 Ukrainian citizens and operated multiple offices in Kyiv and surrounding areas, with members responsible for building and maintaining fake websites, contacting potential victims, and providing security.Victims come from multiple countries, including Germany, Poland, Lithuania, Latvia, Spain, France, the United Kingdom, Canada, and Israel. The police traced the gang's server equipment located in the Netherlands and obtained a database stored there, which included a list of victims, cryptocurrency wallet addresses, suspected stolen amounts, internal communications, and platform operation information. The Ukrainian police and SBU subsequently executed 34 searches in Kyiv and surrounding areas, seizing over 100 computers, more than 100 mobile phones, 79 SIM cards, documents, cash, and 15 vehicles.

This set of posts seems to be the first public exposure of James's formal relationship with Polymarket. Polymarket, as well as representatives from James and the 76ers, did not immediately respond to The Block's request for comment. Previously, James's free agency decision generated approximately $273 million in related contract trading volume across major prediction platforms, according to Legal Sports Report, surpassing any single basketball game; data from Front Office Sports indicated that the related trading volume on Kalshi was about $226 million, while Polymarket's international platform exceeded $43 million.Most traders bet on the wrong outcome: before the official announcement, the odds of the 76ers winning were only about 9%, while the Heat were around 45%. James subsequently signed a two-year, $8 million contract with the 76ers, which includes a player option. Additionally, James had signed a multi-year talent ambassador agreement with DraftKings in 2024. Some fans expressed criticism of James's collaboration with prediction platforms in social media comments.

According to Polish Radio, the Polish House of Representatives failed to overturn President Karol Nawrocki's veto of the cryptocurrency market regulation bill. In the vote, 241 of the 442 attending members supported overturning the veto, 198 opposed it, and 3 abstained, falling 25 votes short of the required 266. This is the third time Karol Nawrocki has vetoed the bill. The bill proposes that the Financial Supervision Authority (KNF) be responsible for regulating the cryptocurrency market. The president believes the bill is overly regulatory and could force Polish businesses to relocate. Prime Minister Donald Tusk called for support of the bill before the vote and mentioned the investigation into the defunct Zondacrypto exchange.

On Tuesday, the Ukrainian National Police and Security Service announced the dismantling of a fake investment platform network based in Kyiv. This gang stole cryptocurrency from users in over 20 countries through built-in wallet theft tools. Investigators have currently confirmed 62 victims, including citizens from Germany, Poland, Lithuania, Latvia, Spain, France, the UK, Canada, and Israel. The organizers recruited more than 46 Ukrainians, operating multiple offices in Kyiv and surrounding areas, where developers were responsible for building the fake platform and resisting bans, while other members handled customer service and security.According to the Ukrainian Security Service, the organizer is a 25-year-old IT expert, and the gang's peak monthly revenue reached up to $1 million. The scam began with advertisements for cryptocurrency investment projects on Telegram. After users registered, they connected their wallets and invested funds, while gang members manually forged transactions to show a continuously increasing balance in the user backend. When users requested withdrawals, the platform required them to connect their main wallet and approve a small "test" transaction under the pretext of verification. This authorization immediately triggered the built-in theft tool on the website, transferring assets to wallets controlled by the gang and locking the victims' accounts.Investigators tracked down server equipment storing the gang's database in the Netherlands, which recorded victim information, wallet addresses, stolen amounts, internal communications, and platform operation data, as well as user passports, phone numbers, emails, login passwords, and photos. Police executed 34 searches in Kyiv and surrounding areas, seizing over 100 computers, more than 100 mobile phones, 79 SIM cards, one GSM gateway, cash, and 15 vehicles.

Polygon Labs announced that it has completed a SOC 2 Type 1 examination for the Polygon Open Money Stack API and dashboard, covering the security trust services criteria. The independent auditing firm Schellman & Company, LLC determined that Polygon has implemented appropriate security controls.SOC 2 is an auditing framework established by the American Institute of Certified Public Accountants.

According to The Block data panel, the combined trading volume of Kalshi, Polymarket, and Polymarket US in August fell by 14.5% month-on-month to $45.33 billion, marking the first monthly decline in a year. Among them, Kalshi's trading volume in August was $37.17 billion, down 7.3% from $40.1 billion in July; the combined trading volume of Polymarket and its US platform was $8.16 billion, down 36.7% from $12.89 billion in July.The decline in August occurred after a surge in summer prediction market activity driven by the World Cup (June 11 to July 19), but the August trading volume was still significantly higher than May's $25.66 billion. Meanwhile, Kalshi and Polymarket are facing increasingly stringent scrutiny from state-level regulators in the US, particularly regarding sports-related contracts, with more than ten states taking enforcement actions or filing lawsuits against the two platforms. Last week, Connecticut sued Kalshi, seeking to prevent the platform from offering sports contracts.Despite the escalating legal disputes with state regulators, Kalshi continues to expand its presence in the sports sector, recently signing an agreement with the United States Tennis Association to become the exclusive prediction market partner for the US Open. Additionally, earlier this week, Kalshi permanently banned former US Congressman George Santos, marking its first permanent ban, due to Santos violating rules by betting on whether he would attend the State of the Union address, resulting in a fine of over $71,000.

According to CoinDesk, U.S. Treasury Secretary Yellen has reportedly urged Japan to raise interest rates to curb the continuous depreciation of the yen, highlighting how traditional monetary policy is susceptible to government and external factors.In contrast, Bitcoin's monetary policy is pre-set by code, with new coin issuance following a fixed rhythm and halving approximately every four years, providing higher predictability. However, Bitcoin still struggles to escape the impacts of traditional financial markets in the short term.If Japan's interest rate hike leads to a rapid appreciation of the yen, long-accumulated low-interest yen financing trades may be closed out, potentially triggering sell-offs in stocks, bonds, and crypto assets. In August 2024, the Bank of Japan's interest rate hike strengthened the yen and put pressure on risk assets, including Bitcoin.From a technical perspective, the BTC 50-day moving average is currently trending upward and is close to crossing above the 200-day moving average, which may form a "golden cross." However, analysts believe that moving averages have a lagging nature, and the historical predictive effectiveness of the golden cross as an independent indicator is not stable.
