Vietnam $3.8B gambling case in a world of rising crypto crime
Vietnamese authorities have dismantled a criminal ring that used cryptocurrency to launder illicit gambling profits, AFP reported, citing local media. The group converted local currency into digital assets such as USDT and Ethereum, routing funds to users for online betting. Operating multi-layered investment websites, the network grew to as many as 20,000 users and managed 25 million accounts, despite Vietnam’s ban on cryptocurrency. In total, the transactions involved were valued at roughly $3.8 billion. Police allege that millions of dollars were funneled into real estate, luxury cars, and cross-border cash transfers.
While the money laundering probe continues, the gambling case has already produced convictions. Four Vietnamese siblings who ran the network, along with 39 other defendants, received sentences in Ho Chi Minh City ranging from a three-year suspended term to 13 years in prison. An Indian national identified as the alleged mastermind remains at large.
Thai police foil crypto-themed fraud
Elsewhere in the region, police in neighboring Thailand busted a South Korean crime syndicate based in Pattaya that allegedly stole more than 20 billion won ($14.2 million) through fraud schemes that invoked cryptocurrency as a lure, along with other scams, the Chosun Ilbo reported.
The scam ring reportedly obtained customer data from a lottery tip site and collected money from victims either by posing as agents offering membership refunds or by claiming to provide compensation for leaked personal information, which they disguised as opportunities to buy digital assets. In addition to these schemes, the syndicate ran romance scams and posed as authorities.
Thai police arrested 20 members in a June resort raid. Nine more suspects, including ringleaders, remain in custody awaiting extradition. Seoul police said that, in total, 25 members have been caught, 21 of whom are now detained. Authorities believe the network may be linked to other groups in Thailand and are widening the investigation.
Europe uncovers $120M crypto fraud
Crypto crimes aren’t limited to Asia. In Europe, police arrested five suspects in a Eurojust-led operation that uncovered an online investment scam worth at least €100 million ($116.8 million). Operating since 2018 across 23 countries, the scheme lured victims with platforms promising high returns, then funneled deposits through Lithuanian accounts before disappearing. In a report by the Organized Crime and Corruption Reporting Project, Elliptic Chief Scientist Tom Robinson said such schemes often have little to do with cryptocurrency itself, instead exploiting its technical obscurity and the allure of quick gains.
Beyond scams, outright theft from crypto platforms is also climbing. A Chainalysis study found that by the end of June 2025, more than $2.17 billion had been stolen from exchanges and related platforms—already surpassing the total for all of 2024. The firm projects losses could reach $4 billion by year-end. The single largest incident was the February hack of the Bybit exchange, in which thieves took $1.5 billion, roughly 69% of all funds stolen in the first half of this year.
Crypto crime turns increasingly violent
The Chainalysis report also flagged a rise in physical attacks, in which criminals use violence or coercion to force individuals to hand over their crypto holdings. The firm warned that 2025 may log nearly twice as many cases as the worst year on record, noting that the attacks often rise and fall with expectations for Bitcoin’s price.
In response to these threats, Chainalysis stressed the need for a multilayered approach to crypto security. It advised service providers to strengthen internal controls through regular audits and employee screening, while upgrading wallet infrastructure and other technical defenses. For individuals, the firm said, keeping holdings discreet has become as critical as technical safeguards, especially amid the rise in physical attacks.
