A study finds that weekend TradFi perpetual contract trading volume surged to $53 billion in August, a nearly 12-fold increase so far this year.

Singapore’s DBS Bank and Citibank’s New York branch completed the first weekend U.S. dollar payment between Singapore and the U.S. on September 5 via Swift Digital Ledger, settled using tokenized deposits. DBS noted the transaction took just minutes, while traditional cross-border U.S. dollar payments typically take up to two business days. The trial aims to overcome limitations of traditional banking hours, weekends, and time zones to enable 24/7 cross-border fund transfers, with relevant use cases including cross-border e-commerce and digital services. Citigroup joined Swift’s tokenized deposit-based 24/7 cross-border payment pilot in July this year and plans to participate in building the U.S. tokenized deposit network. DBS launched its blockchain-based banking system in 2024, which includes DBS Treasury Tokens for liquidity management.

Michael Gubbins, head of Ireland’s Criminal Assets Bureau (CAB), stated that local organized crime gangs have begun renting private vaults to store crypto wallet private keys and mnemonic phrases, alongside assets such as cash, luxury watches, high-end goods, and passports. This practice was uncovered in CAB investigations and has been reported to Ireland’s Anti-Money Laundering Committee. Gubbins noted that criminal groups view crypto assets as anonymous, reducing the risk of their assets being seized, but he pointed out that crypto’s use in Irish criminal activities remains “fairly basic”, with cash still the primary funding source for illegal activities like drug trafficking. Ireland is currently preparing to implement new EU anti-money laundering rules, which will ban cash transactions exceeding €10,000 and strengthen oversight of sectors including crypto asset service providers and luxury goods retailers.

Dongcha Beating AI News Flash: Zhihu recently established Beijing Zhizhe Exploration Technology Co., Ltd., with a registered capital of 1.5 billion yuan, and Zhou Yuan, founder of Zhihu, serving as its legal representative. The new firm is wholly owned by Beijing Zhizhe Tianxia Technology Co., Ltd., Zhihu’s core domestic operating entity, and its business scope covers big data services, internet data services, AI basic software and application development, etc. Notably, the 1.5 billion yuan refers to the shareholders’ subscribed registered capital, not equivalent to Zhihu’s actual cash injection of 1.5 billion yuan.

The establishment of the new company comes as Zhihu accelerates its AI commercialization drive. Zhihu has expanded its AI business to areas including AI search, brand content assets, expert data solutions, and developer tools, but management previously noted that the AI business is still in the commercial verification stage and has not yet generated stable, large-scale revenue.

Bitmine Chairman Tom Lee recently opined that Ethereum (ETH) is more akin to "digital land" than cash. Lee contends that the core value of high-quality assets lies in their store-of-value capacity—i.e., investors’ confidence that they can properly hold and allocate capital over the long term. He points out that stocks qualify as store-of-value assets because investors purchase them with the expectation that the issuing company will manage capital effectively; real estate, meanwhile, combines store-of-value and cash flow attributes, generating returns through rental income. Within this framework, Lee argues Ethereum is closer to stock markets or land, with its long-term value stemming primarily from the network itself as underlying infrastructure. Bitmine has been increasing its Ethereum holdings weekly for 65 consecutive weeks. As of August 30, 2026, its total ETH holdings reached 5,901,112 units, accounting for roughly 4.9% of Ethereum’s total supply.

Bitcoin is facing multiple key macroeconomic events this week. The U.S. August PPI and CPI data will be released on Thursday and Friday respectively, while the Federal Reserve will announce its interest rate decision on September 16. CME FedWatch data shows the market currently assigns a 58.4% probability to the Fed raising rates by 25 basis points to the 3.75%-4% range. Meanwhile, Japan’s record foreign exchange intervention and potential U.S. Treasury bond sales have also become a market focus. Japan’s foreign exchange reserves have decreased by approximately $79.57 billion since the end of July, leading markets to believe Japan may sell U.S. Treasuries to fund yen interventions. Polymarket data shows the probability of the Bank of Japan raising rates by 25 basis points in September has now reached 98%. Fluctuations in the yen and carry trades could further impact global liquidity and crypto markets. On-chain data from CryptoQuant points out that Bitcoin’s recent rally has been driven primarily by the futures market, with no corresponding confirmation from spot demand. Derivatives open interest rose by approximately $2.3 billion in a single day to $27.53 billion, while spot demand remains negative, casting doubt on the sustainability of the current rally. Technically, Bitcoin closed above $80,000 on its weekly chart for the first time in several months this week, though strong selling pressure remains near the $80,000 level. Meanwhile, Bitcoin’s weekly Supertrend indicator flipped to a "buy" signal for the first time since November 2025, a similar signal that emerged after the bear market bottomed in early 2023.
