Celsius CEO Gets 12-Year Prison Sentence
Former Celsius Network CEO Alexander Mashinsky received a sentence of 12 years in U.S. federal prison after pleading guilty in December to commodities fraud and manipulating the Celsius token. Mashinsky admitted to defrauding investors through misleading claims about the safety and profitability of Celsius’ platform, while secretly selling off millions in personal holdings. His legal troubles began in 2023 alongside a $4.7 billion settlement Celsius reached with the Federal Trade Commission. Regulatory agencies, including the Securities and Exchange Commission and Commodity Futures Trading Commission also sued him for fraud.
German Police Shutter eXch
German federal police shuttered the eXch cryptocurrency exchange and seized its server infrastructure for allegedly facilitating money laundering linked to cybercrime. Authorities confiscated eight terabytes of data and digital assets worth $38 million, marking the third-largest crypto seizure in BKA history. The platform reportedly bypassed KYC regulations, enabling the transfer of an estimated $1.9 billion in cryptocurrency, some suspected of originating with criminal sources. Investigators say North Koreans funneled through eXch part of the $1.5 billion they stole in the February Bybit hack. eXch denied involvement, it shut down operations on May 1. The exchange’s operators are under investigation for commercial money laundering and running a criminal trading platform.
Haowang Guarantee Shuttered
Haowang Guarantee, once considered the world’s largest illicit online marketplace, has shut down after Telegram blocked its channels and non-fungible token groups. The platform facilitated sales of personal data, money laundering services and technology to Southeast Asian crypto scammers. Elliptic once said Haowang processed over $27 billion in USDT transactions, aided in part by USDH – a stablecoin tied to Cambodia’s Huione Group. The U.S. Department of Treasury has accused Huione of laundering $4 billion, some linked to North Korean cyberattacks.
Kidnapping Attempt on Crypto CEO’s Family
Parisian police are investigating an attempted kidnapping involving the 34-year-old daughter of a cryptocurrency CEO and her two-year-old child, reported Le Parisien.
The attack occurred in broad daylight and was captured on nearby surveillance footage. Three masked men tried to seize the victims, but the woman’s husband intervened, forcing the assailants to flee and abandon their vehicle. The incident is the latest in a series of “wrench attacks,” where criminals use physical threats to steal crypto assets. France has seen at least five such attacks this year, including the torture and ransom of Ledger co-founder David Balland.
ISIS Supporter Sentenced to 30 Years in Prison
Mohammed Azharuddin Chhipa, 35, received a sentence of more than 30 years in U.S. federal prison after being convicted of conspiracy and multiple counts of providing material support to a foreign terrorist organization. Between 2019 and 2022, Chhipa raised over $185,000 through online donations and in-person collections, which he converted into cryptocurrency and sent to recipients in Turkey. Evidence showed the funds ultimately reached ISIS operatives in Syria and supported prison breaks, logistics and fighters’ welfare.

Mazhar sold false bank accounts, credit cards, malware and ransomware via a website. Authorities also found he laundered cryptocurrency worth 80,000 euros at the time of his 2022 arrest, which has since appreciated to 200,000 euros and was forfeited to the state.
