Brazilian crypto exchange Mercado Bitcoin said it will begin restoring customer account access on Monday after a hack that blockchain analysts estimated stole more than $46 million in assets. Initially, customers can only view balances, statements, holdings and investments through the website, while transfers, withdrawals and trading will resume in later phases after independent security testing. The company pledged to use its own funds to replenish affected assets and said more than $15 million in stolen funds has already been frozen with help from the industry. Its trading desk is preparing repurchases in domestic and international markets. The company also cited a $20 million investment from stablecoin issuer Tether, which it said supports operational expansion and a strong cash position.

- Mercado Bitcoin pledges to cover all user losses after near $40 million hack
- Mercado Bitcoin wallets keep moving funds after $46M hack
Brazilian crypto exchange Mercado Bitcoin confirmed a security incident in which over $46 million in cryptocurrency was drained from wallets on Monday, and paused deposits and withdrawals, saying customer funds and data were safe. Despite the suspension, addresses linked to the incident kept receiving funds for hours, and security firms said the hack was carried out through standard transfers rather than a smart contract exploit. An initial post-mortem by Certik's Dickson Wu described small ETH transfers from 27,160 addresses and warned that the attacker could also move money out of customer deposit addresses. According to the article, about $6.2 million had been frozen by Tether and Circle, about $20 million had been moved to new wallets, and over $20 million remained in associated addresses, including all 106 BTC. The hack has not been attributed to an organized group and remains under investigation, coming days after Binance reported a $6.3 billion hack.

- Crypto wallet hack in Southeast Asia causes nearly $100 million in losses
More than $93 million was stolen from hundreds of Ledger hardware wallets sold through Southeast Asian retailer CryptoBilis, after the devices were allegedly implanted with malicious chips. Ledger confirmed at least one affected device had unauthorized hardware, and all confirmed cases up to October 11 involved devices sold through CryptoBilis, though its internal systems show no sign of intrusion. Researchers say the chip could capture screen content and button presses to obtain seed phrases, but this is an inference, and Ledger has not confirmed how or when the tampering occurred. Bitquery estimates $93.2 million was taken from 315 wallets, YFarmX puts the figure at $94.5 million from 521 addresses, and Tether froze $10 million. CryptoBilis has paused sales and shipments of hardware wallets, and Ledger advises not using unset-up devices bought from it in the past 90 days, while existing users should move funds to new devices with new recovery phrases.
- Ledger claims CryptoBilis cases are limited as up to $93M is traced, $10M frozen
Ledger said every confirmed case involves devices sold by the authorized reseller CryptoBilis, though critics argue the hardware-wallet maker must answer for that sales channel. Blockchain analytics firms estimate attackers stole between $93.2 million (Bitquery) and $94.5 million (YFarmX) from wallets linked to these devices, though Ledger has not confirmed a total. Ledger confirmed an unauthorized hardware implant in at least one affected device, and Tether froze $10 million in USDT tied to the theft. Bitquery said about $81 million could still be traced onchain as of Oct. 11, with some funds moved through Tornado Cash and Zcash. Ledger advised CryptoBilis customers not to set up unused devices and, if they already use one, to move assets to a new device with a newly generated recovery phrase.
- Tether Holds 150,000 Bitcoin, CEO Says—About 50,000 More Than Its Reserve Report Shows
Tether CEO Paolo Ardoino said the company holds about 150,000 Bitcoin, worth roughly $11.5 billion, about 50,000 coins more than its Q3 reserve attestation implies. That attestation lists $8.37 billion of Bitcoin at $83,621 per coin, or roughly 100,060 BTC, leaving around 50,000 coins (close to $3.8 billion) not reflected in its public filings. Ardoino did not say where the extra Bitcoin is held or when it was acquired, and Tether has said its corporate Bitcoin sits separately from the reserves backing USDT. The company has accumulated Bitcoin for years and reported $1.5 billion in net operating profit in the third quarter alone. The issue touches on Tether's long-running scrutiny over USDT backing, as it began its first full financial audit with KPMG this year.

- Plain gold ring and gold bar prices rise simultaneously on Nov. 5 at SJC, PNJ, Bao Tin Minh Chau, DOJI and Bao Tin Manh Hai

- Amazon workers in the Greater Toronto Area launch fight for better jobs with Unifor
Amazon workers across the Greater Toronto Area have launched a new organizing drive with Unifor, seeking safe jobs, fair pay and respect ahead of Black Friday. The union notes Amazon reported US$28.1 billion in operating income in Q3 2026, with an operating margin of almost 14%, its highest ever, while many associates received a wage increase of only $1/hour in 2026. Workplace Safety and Insurance Board data shows Amazon's 2025 injury rate was more than double its 2020 level, and annual injury claims have nearly tripled. Ontario holds more than half of Amazon's Canadian workforce, and workers at the YVR2 warehouse in Delta, B.C. are close to securing the first collective agreement at Amazon in North America. Unifor, Canada's largest private-sector union with 320,000 workers, says workers have a legal right to organize.

- A 'demand decade' ahead for energy? BP, Baker Hughes CEOs weigh the investment outlook
Rising energy demand is opening new investment opportunities, though geopolitical risks and uncertain oil prices are challenging the industry. Baker Hughes CEO Lorenzo Simonelli is optimistic about the long term, citing AI, population growth and developing nations, and says the industry has a 'demand decade' ahead. He expects industry activity to rise by a low-single-digit percentage in 2027 and says the Middle East conflict highlights the need for more resilient infrastructure, including storage and pipelines. RWE CEO Markus Krebber says AI and electrification are driving electricity demand, but geopolitical tensions, supply chain pressures and higher interest rates are complicating investment decisions. BP CEO Meg O'Neill stresses that wide forecast ranges for global energy demand matter for long-lived projects, while Energy Aspects expects oil markets could be oversupplied in 2027 and 2028 if Middle East flows return to normal.
