US regulators contacted banks about possible system vulnerabilities after last week's $6.3 billion Binance hack, according to sources familiar with the matter. Several sources said Federal Reserve and Office of the Comptroller of the Currency supervisors began asking banks on Monday morning about unusual activity or service disruptions. Two other people familiar with banks' efforts said banks are examining the attack and testing defenses against similar attacks. A source at one contacted bank said the bank experienced no service disruptions. Binance said the company did not know whether the hack affected US banks, while the Fed and OCC declined to comment.

Bitcoin climbed above $81,000 alongside gold after the US midterm elections, renewing speculation that investors were protecting wealth against dollar depreciation. However, improving market sentiment and lower Treasury yields could explain the gains without a fundamental reassessment of the dollar. CoinGlass data showed approximately $378 million in bearish crypto positions liquidated within one hour, raising doubts about fresh demand. US spot Bitcoin ETFs attracted $74.6 million on Nov. 4 after approximately $1.16 billion in withdrawals over the preceding three trading sessions. Holding the $75,700 to $77,700 range alongside sustained ETF inflows would strengthen the currency-debasement explanation.

South Korea has announced a fourth postponement of the crypto gains tax, moving the planned start from January 2027 to 2029. However, the National Assembly must still approve the change. The proposed levy would charge 22% on annual crypto profits exceeding 2.5 million won ($1,870). Officials cited the timing of US tax-information exchanges and unfinished tax rules, while analysts said declining support among young investors was decisive. In contrast, Hong Kong passed legislation on Wednesday requiring crypto user-data collection from 2027 and information exchanges from 2028.

SoSoValue data show that US-listed spot Bitcoin ETFs received $74.6 million on Wednesday, ending three trading sessions of net withdrawals. US-listed spot Ether ETFs received $53 million, ending seven days of withdrawals. Fidelity's Wise Origin Bitcoin Fund led Bitcoin ETF inflows with roughly $237 million. However, Farside Investors data show that BlackRock's iShares Bitcoin Trust lost $201.2 million, extending withdrawals to four trading sessions. Bitcoin rose above $80,000 following Democrats' US midterm election victories, but CoinShares research head James Butterfill cautioned against overstating the election's influence on Bitcoin's performance.

South Korea's government has endorsed a two-year postponement of the 22% tax on cryptocurrency gains to 2029, which would mark the fourth delay. Finance Minister Lee Hyoung-il said Thursday that the government would discuss delaying the January 2027 start date with lawmakers. The government said taxing gains before information exchanges with the US begin in 2029 could disadvantage the domestic market. Officials also plan a provision allowing investors to offset crypto losses against profits over the next three years.

The record $6.3 billion theft from Binance has exposed the difficulty of recovering stolen money from crypto systems designed for unrestricted transfers. Tether and Circle froze some stolen tokens using centralized controls, but billions of dollars remained beyond recovery efforts despite real-time blockchain tracking. Decentralized-finance provider Unit has added deposit and withdrawal delays to help identify potentially stolen assets. Aave community members are seeking limits on fund flows following the hack. However, restoring controls and delays does not guarantee safety, and traditional financial institutions have security weaknesses of their own.

Vitalik Buterin said Ethereum will use advanced technologies, including GPUs, over the coming years to process multiple tasks in parallel while preserving decentralization. Buterin said the Ethereum Foundation will concentrate on the foundation's strengths and help developers improve technical standards, security, privacy and openness. Users and the community will explore areas outside the foundation's expertise, Buterin said.

France's National Assembly rejected the revenue section of the 2027 state budget late Wednesday, excluding three adopted crypto amendments from the bill going to the Senate. The official voting record shows 458 votes against the section, none in favor and two abstentions at first reading. The amendments would tax crypto-to-stablecoin gains, require disclosure of self-custodied crypto holdings worth at least 100,000 euros ($112,000), and raise penalties for crypto platforms that fail to provide requested tax information. The proposals could return in the Senate but must pass the remaining budget stages to become law.

India's cybersecurity agency said the hacking group Crafty Falcon has breached non-bank lenders, fintech companies and cryptocurrency exchanges using publicly available AI tools. The agency identified four tools, at least two of which security researchers have linked to China. The agency said attackers transfer money through victims' payment and disbursement systems and described the threat as continuing. The agency did not attribute the attacks to a state or identify which recent financial-sector incidents involved Crafty Falcon.

DDC Enterprise announced a preferred stock initial public offering expected to raise $24 million. The initial offering price is $20.

Hong Kong has enacted legislation requiring crypto exchanges and other covered service providers to collect customer information and transaction records for taxation from 2027. The government said automatic information exchanges with overseas tax authorities will start in 2028. The law implements the OECD's Crypto-Asset Reporting Framework without making customer information public. Hong Kong's secretary for financial services and the treasury, Christopher Hui, said the requirements would help counter cross-border tax evasion.

Ripple-backed Evernorth submitted a preliminary registration covering 73.7 million shares for potential resale after a sharp decline following its Nasdaq debut. XRPN closed at $11.98 on Nov. 3, approximately 38% below its October 12 debut-day high of $19.39. The registration does not show that the named investors have sold shares or plan to sell their entire holdings. Ripple and certain other major investors face six-month transfer restrictions, generally until April 9, 2027, with specified exceptions. Evernorth warned that substantial shareholder sales, or expectations of selling, could push its stock price lower.

OpenAI said the company's AI identified 948 Linux kernel flaws and produced a working attack for every flaw, at $1,279 per instance. The attacks allow someone with limited access to a Linux computer to gain complete control. OpenAI said the research aims to help defenders discover and fix vulnerabilities before hackers exploit the vulnerabilities. Most blockchain infrastructure uses Linux, and ethernodes.org puts Linux usage among Ethereum nodes at about two-thirds. Polygon Labs chief technology officer Mudit Gupta said decentralization makes crypto more resilient to such flaws than traditional software. The findings come from OpenAI, and the underlying model remains unreleased.

Arkansas Attorney General Tim Griffin has sued Kalshi for allegedly running an illegal gambling platform in Arkansas. Griffin said on Wednesday that Kalshi exposes users to excessive wagering, financial losses, depression and other mental health harms. Kalshi has argued in other lawsuits that federal derivatives regulation covers Kalshi's event contracts, exempting the contracts from state gambling laws. Utah filed criminal charges against Kalshi and two executives last week. The Commodity Futures Trading Commission has separately sued at least 10 states over jurisdiction over prediction markets.

Crypto analyst DonAlt sees Bitcoin's trading after the US midterm election as a possible signal of a rally to a record high. DonAlt said Bitcoin's monthly chart became positive after Bitcoin fell to $75,000 on November 4. The Associated Press reported that Democrats won majorities in both the House and Senate. DonAlt challenged the view that Democratic victories would hurt crypto, arguing that more Democratic wins would mean less grifting. Bitcoin's previous record was $126,000 in October of last year.

South Korea's Deputy Prime Minister and Minister of Economy and Finance Lee Hyung-il said the government has decided to delay virtual asset income tax collection by two years until 2029. Lee said obtaining virtual asset transaction data from the United States after 2029 would give the government enough information to tax investors using US exchanges. The government will create and operate a joint public-private working group on digital asset taxation.
