The developers of Cashu have issued a warning about a phishing campaign aimed at infecting Windows machines with malware. On August 20, 2026, the Cashu team reported that attackers are using a fraudulent website that mimics the official one to deceive users into downloading malicious files. Cashu emphasized that it never sends emails to its users and does not collect email addresses. They urged users not to click on suspicious links, not to download files from unsolicited communications, and to avoid running programs sent via email. Cashu is an electronic money protocol based on Chaumian blind signatures, designed to operate over the Bitcoin network, allowing the generation of digital tokens that are stored on users' devices. It is notable for its privacy in peer-to-peer transactions and instant payments with reduced fees, facilitating the conversion between e-cash and bitcoin through the Lightning network. Receiving emails on behalf of Cashu is an indication of a scam attempt.

U.S. major indexes closed lower yesterday. Walmart’s weaker-than-expected same-store sales and guidance weighed on the consumer sector and dragged the three major averages lower. Silver and platinum rose sharply, supported by lower yields from expanded long-bond buybacks and a softer dollar. Bitcoin climbed toward $75,000, lifting crypto-related equities. Markets are now focused on the August S&P Global Manufacturing and Services PMI flash readings due on August 21 U.S. Eastern Time, which will directly influence September rate-path pricing.






Expanded U.S. Treasury long-bond buybacks helped pull yields lower and supported a modest rebound in risk appetite, with the major indexes closing slightly higher. At the same time, Bitcoin briefly rose above $70,000 and lifted crypto-linked equities, while positive Phase 3 vaccine data from Merck and Moderna pushed healthcare and biotech stocks higher. SK Hynix’s large-scale buyback also kept attention on the storage cycle and AI-related demand. Markets are continuing to digest the relatively hawkish Fed minutes while positioning ahead of earnings from Alibaba and Walmart.
