cryptocurrency

Cryptocurrency, or digital currency, is a type of digital or virtual currency based on blockchain technology, utilizing cryptographic techniques to ensure transaction security, control the generation of new units, and verify asset transfers. Its decentralized nature means it does not rely on central banks or government institutions. Bitcoin is the earliest and most well-known cryptocurrency, while other notable cryptocurrencies include Ethereum, Ripple, and others. Cryptocurrencies are used for various purposes such as payments, investments, and executing smart contracts, and they have high volatility and potential high return risks.

Grayscale: The various sectors of cryptocurrency are gradually decoupling from Bitcoin's trend, with volatility generally higher than that of Bitcoin

According to a report by Crypto Briefing, Grayscale's research indicates that the correlation between crypto assets and Bitcoin is decreasing, with Bitcoin currently explaining only about 50% of the return volatility across various crypto sectors.The report breaks down the annualized volatility and the impact of Bitcoin-related factors by sector: the annualized volatility of the currency sector is 49%, with 43% attributed to Bitcoin; the annualized volatility of the smart contract platform sector is 58%, with 38% attributed to Bitcoin; the annualized volatility of the finance sector is 59%, with 30% attributed to Bitcoin; the annualized volatility of the utilities and services sector is 67%, with 30% attributed to Bitcoin; the annualized volatility of the consumer and culture sector is 76%, with 46% attributed to Bitcoin; the artificial intelligence sector has the highest annualized volatility at 85%, with only 35% attributed to Bitcoin.The research points out that Bitcoin's own annualized volatility has recently been around 43%, while the volatility of all sectors tracked by Grayscale is higher than that of Bitcoin. The report suggests that lower correlation does not imply lower risk, but the fact that Bitcoin explains only half of the return volatility means that the other half is driven by factors specific to each sector, providing investors with a reference for assessing which sectors can offer true diversification.

first_img U.S. Department of Justice: North Korean hackers use deepfake video calls to steal over $400 million in cryptocurrency assets

The U.S. Department of Justice stated on Thursday that North Korean hackers have stolen over $400 million in cryptocurrency assets through a social engineering scheme based on secretly recorded videos and AI deepfakes over the past 18 months, and announced that it has seized the infrastructure supporting this operation. The FBI refers to this method as "FaceStealer," which centers on turning video conference calls into traps: hackers lure targets into meetings using previously stolen accounts from victims, then play pre-recorded footage of trusted contacts to simulate their presence, thereby gaining the target's trust.The group also uses AI to generate deepfake videos of well-known figures in the cryptocurrency and related industries, making the scams more convincing. Once the target lowers their guard, the attackers create false technical issues, such as claiming the other party cannot hear them, and provide a so-called "fix" link that is actually used to implant malware. Afterward, hackers can empty the victim's wallet or exploit their system permissions, sometimes lying in wait for months or even over a year before taking action. The FBI stated that it has seized over 900 segments of camera footage from FaceStealer victims based on federal search warrants.The Department of Justice linked this operation to North Korean-related groups such as Sapphire Sleet, BlueNoroff, and APT38, warning that these hackers are increasingly targeting open-source software developers, seemingly paving the way for supply chain attacks. On the same day, the Department of Justice also reported progress in the Binance theft case, stating that it has obtained court authorization to seize or restrict over $1.2 billion of the approximately $6.4 billion in stolen assets, which is part of the over $2.7 billion that has already been frozen. The FBI attributes this theft to the North Korean group TraderTraitor and claims it is laundering money at a rate of creating a new wallet approximately every 25 seconds. North Korea denies involvement, stating that the FBI's conclusions are a political provocation.

first_img The New York Department of Financial Services issued advertising marketing guidelines for licensed cryptocurrency entities

According to The Block, the New York State Department of Financial Services has issued new guidelines for advertising and marketing requirements for licensed cryptocurrency entities in the state, which include avoiding misleading or deceptive content. Acting Superintendent Kaitlin Asrow stated in a press release that today's guidelines reinforce the commitment to protecting New York residents and ensure that advertising and marketing practices in the virtual currency space are clear, comprehensive, and accessible.The New York State Department of Financial Services announced on the same day that these guidelines apply to virtual currency entities licensed or chartered by the department, requiring them to establish and implement policies and procedures for advertising and marketing materials related to virtual currency products, services, and activities, with a focus on content accuracy, clear disclosures, and governance and review processes. Relevant entities must update their policies and procedures according to the guidelines by May 10, 2027, review them at least once a year, and maintain records for regulatory inspection. The Department of Financial Services will assess the implementation and effectiveness of these policies and procedures through examinations and ongoing supervision.Common practices listed in the guidelines include: reviewing marketing claims to ensure they fairly present products, services, or activities, are supported by evidence and verifiable, and do not contain exaggerated or false statements about performance or regulatory status; customer disclosures should be clear, prominent, easily understandable to the general audience, and clearly identify the entity providing the products, services, or activities; establishing governance review processes for advertising and marketing materials, designating responsible parties, conducting due diligence on third-party promoters, and promptly monitoring and addressing instances of fraudulent or improper use of their name or brand by others.

Bloomberg: Wintermute wins approximately 76% of the priority data auction for Hyperliquid

According to Bloomberg, the crypto market maker Wintermute has become the main user of Hyperliquid's priority data auction mechanism. This mechanism allows traders to bid for the right to view incoming buy and sell orders before they are processed by the exchange, giving them a few milliseconds to adjust their quotes or hedge on other platforms.Blockchain analytics platform Loris Tools found that in the past month, a wallet associated with Wintermute won about 76% of the highest priority data slot auctions.This mechanism has raised questions about whether it favors large trading firms. DRW founder Don Wilson previously questioned whether it is fairer than the server hosting mechanisms of traditional exchanges and whether it can meet U.S. regulatory requirements.The founder of Loris Tools believes that to fully leverage this speed advantage, direct connections to nodes operated by the Hyperliquid Foundation are necessary, and this access has trading volume and token staking requirements.Wintermute founder and CEO Evgeny Gaevoy stated that the auctions are more transparent than the low-latency networks and server hosting of traditional finance, and the company primarily uses this service for cryptocurrency trading. Hyperliquid Labs stated that anyone can participate in the bidding, and all priority fee payments are publicly recorded on-chain.

A British criminal planned to steal 2.7 million dollars in cryptocurrency while in prison and was sentenced to 8 years

According to The Block, the High Court of Scotland sentenced Robert Barr to eight years in prison for remotely orchestrating a theft of approximately £2 million (about $2.7 million) in cryptocurrency while serving his sentence in Edinburgh prison. Two accomplices, Iain Doyle and Sean Favier, received sentences of five years and four years, respectively; all three had previously pleaded guilty to involvement in organized serious crime.The court revealed the method of operation: Barr had his accomplices enter the victim's home and asked the homeowner to download the remote control software AnyDesk, which he then used from prison to control the couple's computer, inputting a receiving address he controlled to transfer funds from the victim's wallet. On the evening of April 17, 2024, around 11:30 PM, Favier and Doyle arrived at the couple's residence but were captured on the doorbell camera; the homeowner refused to open the door, and the two were unable to enter, resulting in a failed plan.Judge Lord Cubie described this as "a crime that combines 21st-century computer technology with old-fashioned burglary." On June 25, 2024, police seized Barr's mobile phone and discovered detailed messages directing his two accomplices; the judge noted that Barr had previously served 21 months for cryptocurrency-related fraud but organized crime again while in prison, which constituted "significant aggravating circumstances." If convicted at trial, he should have received a sentence of eight years and ten months. Barr is scheduled to attend a serious crime prevention order hearing on November 17.
