Datachain Secures Funding from Japan’s MUFG to Advance Blockchain Interoperability Initiatives

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.Photo by Amanda Jones on UnsplashThai police foil crypto-themed fraudElsewhere 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 fraudCrypto 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 violentThe 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. 

Bitmain to Launch Filecoin Token Mining MachinesBitmain, the well-known Chinese manufacturer of Bitcoin mining machines, has made a significant announcement that marks its entry into the Filecoin ecosystem.FIL token miningAccording to that announcement made by the company on social media on Friday, the company is set to launch FIL token mining machines, which are expected to have a hash rate of up to 4,300T each and will be available for purchase at $38,888 per unit.Filecoin, created by Protocol Labs, was originally designed as a blockchain-based collaborative digital storage and data redemption solution. As an open-source, public cryptocurrency and digital remittance system, Filecoin has garnered significant attention in the market.Photo by Traxer on UnsplashDelegated stakingAlong with the mining machine development, Bitmain has introduced a delegated staking service with a low monthly fee of 0.5%. This service offers traders an opportunity to earn more through staking with minimal computational energy. Delegated staking allows users to delegate their staking rights to validators or staking pools, enabling them to partake in the rewards generated by these validators.According to a recent report by crypto market intelligence firm Messari, Filecoin’s data storage market continued to grow in Q2, 2023. Active data storage deals grew 64% when compared with the previous quarter. That deal flow resulted in increased revenue from fees, which was up 91%. Further development of the Filecoin protocol resulted in the recent introduction of the Filecoin Virtual Machine (FVM). That runtime environment for smart contracts has enabled new use cases, including liquid staking, decentralized computing, and perpetual storage.Bitmain’s venture into the Filecoin ecosystem not only supports the development of FIL token mining machines but also offers hope for FIL token holders who experienced losses. The FIL unit price peaked at $190 during the 2021 crypto bull market. The company’s involvement has positively influenced Filecoin’s price.Meanwhile Bitmain continues to be a major player in the crypto mining equipment space. 2021 has not been without its blemishes for the company though, as in April the Beijing-based company was fined $3.7 million by the Chinese authorities for a violation of Chinese tax regulations.Bitmain hashrate dominanceEarlier this month, US bitcoin miner TeraWulf purchased 18,500 mining machines from Bitmain, with a view to deploying them at its 43 MW Lake Mariner mining facility in New York State in the US. The deal had a value of $75 million.A recently published report by crypto intelligence firm Coinmetrics outlined that the majority of the Bitcoin hashrate is being processed by Bitmain’s S19 miner model. Three Bitmain miner models are responsible for 76% of the entire Bitcoin network’s hashrate, the report states.

Bithumb and Korbit Struggle to Gain Traction Despite Zero Trading FeesSouth Korean cryptocurrency exchanges Bithumb and Korbit have recently eliminated trading fees, but their bold decision hasn’t yielded much results. Bithumb was the first to implement this change and attracted users for about a week, but it is now seeing a loss in market share. Korbit, following Bithumb’s example, is also struggling to achieve meaningful outcomes.Photo by Alexander Grey on UnsplashLimited impactLocal media outlet Chosun Biz used data from crypto data platform CoinGecko to draw this conclusion. On October 26, Korbit’s daily trading volume represented 0.19% of the total trading volume among South Korea’s top five crypto exchanges (Upbit, Bithumb, Coinone, Korbit, and Gopax). This figure marked a 0.14 percentage point increase compared to the 0.05% recorded on October 19. Korbit had implemented a zero trading fee policy at 9 a.m. (KST) on October 20. Additionally, they launched a promotion offering KRW 5,000 ($3.69) worth of bitcoin to users who transferred virtual assets totaling KRW 1 million or more from Travel Rule-compliant exchanges to Korbit. While the promotion did contribute to Korbit’s market share, it still remains below 1%.Bithumb’s performance showed some improvement, albeit briefly. As of October 26, Bithumb’s market share stood at 18%, marking a 4.7 percentage point increase from its 13.3% share on October 3, the day before it eliminated trading fees. However, it’s worth noting that its market share had reached almost 30% shortly after the promotion’s launch. This indicates that its strategy is losing efficacy over time.The less-than-enthusiastic results from their daring marketing endeavors can be attributed to their inability to draw in retail investors. To begin with, Upbit, the leading player in the market, had already been providing a relatively low fee of 0.05%. Furthermore, adapting to new user interfaces on these exchanges posed a challenge. Zero trading fees weren’t attractive enough for crypto investors to leave their current platforms.Trading volume mattersIn the case of Korbit, its lower trading volume was a disadvantage when it came to attracting users. On crypto exchanges, a higher trading volume typically translates to faster trade executions. As a result, users of Korbit might experience delays in executing trades at their preferred price.Jeong Hye-won, a research associate at crypto data analytics platform Xangle, told Chosun Biz that users on exchanges with lower trading volumes tend to experience slippages due to slower transaction speeds and sparsely populated order books. A slippage means the difference between the initially placed order price and the executed order price. Jeong further explained that Korbit’s zero trading fee policy didn’t have a significant impact because it offers fewer listed tokens compared to Upbit and Bithumb.There is speculation that the free-trading fee promotions introduced by Bithumb and Korbit, despite their revenue sacrifices, might conclude sooner than initially anticipated due to their perceived ineffectiveness. Bithumb derives 99.95% of its revenue from trading fees, while Korbit relies on trading fees for 99.79% of its income. An industry insider has commented that trading fees play a vital role in an exchange’s revenue, and given Bithumb’s reported loss in earnings during the second quarter, there are concerns about their capacity to sustain this strategy.
