Bitfinex stated that Bitcoin typically transfers to trading platforms before being sold, but during the drop of BTC from $87,000, there was almost no behavior of Bitcoin held for 6 months or more.Data shows that nearly all Bitcoin flowing into trading platforms recently has only been transferred in the past week. Bitfinex pointed out that true market capitulation usually requires long-term holders to start transferring and selling their chips, but there are currently no signs of this.

Starknet published an article introducing the Quantum Secure Bitcoin solution (QSB), stating that StarkWare researchers have verified a quantum secure locking mechanism on the Bitcoin mainnet that does not require a soft fork, new opcodes, or modifications to consensus rules. The first QSB output was completed on August 26, 2026, in Bitcoin mainnet block 964,199, with related GPU computing costs dropping from approximately $320 to about $50.QSB constructs the locking mechanism through hash calculations, but each transaction still requires significant computation, and assets transferred into this solution still need to undergo traditional transactions that are subject to quantum risks. This transaction does not comply with the default relay rules of Bitcoin Core, and currently, there are no accompanying wallets, address formats, or recovery processes. StarkWare stated that QSB is an emergency research solution, and a long-term solution will still need to introduce post-quantum signature mechanisms through a soft fork. The comprehensive quantum security of Starknet also depends on the progress of Ethereum's underlying upgrades.

New York Attorney General Letitia James announced that a settlement has been reached regarding former Celsius CEO Alex Mashinsky's alleged fraud against investors, securing a maximum conditional compensation of $35 million and requiring him to permanently exit the securities, commodities, and cryptocurrency industries.Previously, the Federal Trade Commission (FTC) and the Commodity Futures Trading Commission (CFTC) had also imposed industry bans on Mashinsky.

According to Cointelegraph, data from the French Ministry of the Interior shows that from January to mid-August 2026, France has experienced 90 cases involving cryptocurrency-related kidnappings, extortion, and violent thefts, averaging one incident every 2.5 days.Blockchain analysis company Chainalysis reported that as of mid-2026, there have been 30 publicly recorded incidents of violent attacks involving cryptocurrency in France; security company Gart.io tracked 73 real-world attacks occurring in France this year, surpassing the 66 in the United States and 27 in the United Kingdom.Eric Jardine, head of research at Chainalysis, believes that the surge in attacks is likely related to large-scale data breaches. The leak of French tax data and the user data breach disclosed by the cryptocurrency tax reporting platform Waltio in 2026 may have allowed attackers to obtain the identities, addresses, and asset information of cryptocurrency holders.The report also noted that over 40% of related attacks in France involve relatives or acquaintances of the victims, with criminals potentially identifying targets in advance through social media, on-chain data, and leaked information. French authorities are coordinating investigations through a specialized organized crime judicial agency.

The Zcash development team plans to add post-quantum signature support to the network in January. Zakura engineer Roman Akhtariev stated in an engineering blog that the team plans to implement post-quantum signature opcodes in Zcash in January. These opcodes will enable Zcash to verify hash-based signatures, thereby resisting quantum computing attacks. The team has not yet confirmed a specific network activation date. This upgrade aims to prevent attackers from using current public keys to reverse-engineer and forge payment authorizations from wallet owners.The initial phase of this upgrade will protect transparent transactions. Zcash has two payment methods: shielded payments hide the sender, receiver, and amount; transparent payments are similar to Bitcoin, where addresses and amounts are visible on the chain. According to CoinDesk, based on ZecStats data, approximately 11.96 million of the 16.98 million issued ZEC are stored in the transparent pool, accounting for about 70%. The January plan primarily targets this public portion. Additionally, Zakura has developed a private query tool that allows wallets to check balances without exposing associated addresses to the server; the experimental version is available in the "Private queries" settings of the Zcash wallet Vizor.Before the release of Zakura's engineering article, Ethereum researcher Justin Drake warned holders on Thursday to prepare for what he called "bunker mode," stating that in the worst-case scenario, AI could find shortcuts to break the mathematical protections of Bitcoin and Ethereum wallets in "months rather than years."

Co-founder of Glassnode, Rafael Schultze-Kraft, stated based on on-chain data that approximately 6.26 million BTC public keys have been exposed, accounting for 31.2% of the current supply, up from 24.8% at the beginning of 2021.Among them, about 4.33 million were exposed due to address reuse, and approximately 1.94 million are related to script types. He emphasized that this statistic does not indicate that quantum attacks are realistically feasible, nor can it be used to assess the security status of exchanges or custodians.

It adopts a "Blockchain + DID + Super Smart Agent" technical route, compatible with various DID methods, and adapts to mainstream interconnection protocols such as A2A and ANP.

Coinbase CEO Brian Armstrong posted a call for more small-scale governance experiments at the federal level or the establishment of innovation sandboxes. He believes that putting every reform up for nationwide debate unnecessarily increases the costs of learning and trial and error, slowing down the process.Armstrong stated, "Competition is the best consumer protection mechanism in history, and the government is the only sector structurally exempt from competition." He suggested that within specific areas, such as 10 square miles of federal land, faster permitting approvals, relaxed regulations, or different rules should be trialed, and then the implementation results should be re-evaluated, allowing successful practices to be gradually promoted.

According to the City of London Police report, 25-year-old London man Ajay Shinjin (also known as AJ Marley Cruz) was sentenced to two and a half years in prison by the Inner London Crown Court for his involvement in a SIM swap fraud case. He pleaded guilty on September 28 to two charges of conspiracy to commit fraud by false representation and transferring criminal property. The case involved the theft of cryptocurrency worth nearly £200,000 (approximately $265,000).In early November 2021, British telecom operator BT discovered unauthorized activity in its systems, where customers' phone numbers were transferred to SIM cards controlled by criminals, who intercepted one-time verification codes sent by banks and cryptocurrency platforms. The police identified several suspects based on device data provided by BT, and Shinjin was linked to four of the devices. He profited over £44,000, which he used for a vacation in Dubai, a luxury apartment in Canary Wharf, and a gold-plated dental grill.Details of the case revealed that one victim lost approximately £40,000 in cryptocurrency on November 2, 2021, with about £27,000 flowing into Shinjin's personal crypto account; a second victim had approximately £17,000 entirely transferred to his wallet; he also assisted in stealing about £8,000 from a third victim's Coinbase account and around £130,000 from a fourth victim. Shinjin was first arrested at his residence in 2021 and was re-arrested at Heathrow Airport upon returning from Dubai in October 2023.
