first_img After 11 years of operation, BitMEX has stopped trading and deposits, retaining only withdrawals

The cryptocurrency derivatives platform BitMEX has ceased trading, deposits, and opening new positions, retaining only the withdrawal function. The platform announced on social media platform X that as of this Tuesday at 04:00 UTC, the aforementioned services will no longer be available. Users can still log in and withdraw their balances through the official website, but deposits have been confirmed as impossible. BitMEX was co-founded by Arthur Hayes, Ben Delo, and Samuel Reed in 2014, known for promoting perpetual contracts as mainstream trading tools in the cryptocurrency derivatives market.BitMEX urges customers to withdraw their funds as soon as possible and states that account fees will be charged to users with completed KYC certification who still have a balance, billed monthly, at a standard of 1% annualized on assets or a minimum equivalent of $50, whichever is higher. The company emphasizes that this shutdown does not freeze customer assets, and the withdrawal channel remains open during the liquidation process.BitMEX announced its closure in July this year, following a strategic assessment by its parent company HDR Global Trading, as the exchange's market share in the perpetual contract market it helped create continued to decline. According to research data from CoinDesk, the monthly trading volume of centralized cryptocurrency exchange derivatives reached $3.4 trillion in August, with an annual scale potentially reaching $50 trillion. Previously, BitMart also announced its shutdown in July after nine years of operation due to market conditions.

Hunan Public Security in China cracks down on virtual currency pig-butchering scams: 2 suspects have been criminally detained according to the law

According to a report from the Public Security Bureau of Linwu County, Hunan Province, on August 19, 2026, the Public Security Bureau of Linwu County, Chenzhou City, Hunan Province discovered fraud clues during routine inspections and successfully cracked a virtual currency investment fraud case, arresting two criminal suspects.Upon investigation, on May 1, 2026, the suspect Li met the victim, Ms. Yue, through private messages on a social platform, falsely claiming to teach virtual currency investment skills with guaranteed profits. He induced her to download a certain app to purchase Tether (USDT) and then exchange it for a newly issued virtual currency manipulated by his "superior." Li, in collusion with his "superior," created the illusion of rising prices to lure the victim into increasing her investment; once the funds were in place, they quickly crashed the market, causing the virtual currency's value to drop to zero. Ms. Yue lost approximately 30,000 yuan, while Li illegally profited tens of thousands of yuan, which was collected by his friend Lei and squandered.On August 19, the investigating police arrested Li; on September 17, Lei, who was suspected of collecting the stolen funds, was also apprehended. Both have been criminally detained according to the law. The police remind: virtual currency is not legal tender, and there are no "guaranteed profit" projects. Recommendations for high returns made through private messages online are all fraud traps. Do not easily trust investment recommendations from strangers or transfer money to unfamiliar platforms.

first_img French cryptocurrency practitioners' entire family was kidnapped, approximately $46,000 worth of cryptocurrency was transferred away

A family in the northern French town of Vendin-le-Vieil was invaded and taken hostage by four masked men early Sunday morning. According to BFMTV, the suspects entered the house around 4 AM, binding the couple and their two children with tape, and held them for over three hours. The 40-year-old father, an IT expert in the local cryptocurrency industry, was taken to another room, beaten, and forced to give up access codes, resulting in approximately 40,000 euros (about 46,000 dollars) worth of cryptocurrency being transferred away.According to the Béthune prosecutor's office, the four suspects fled the scene by car and are still at large. The 12-year-old daughter was struck in the face with a car key during the incident, and the victims are in a state of shock; they have been sent for forensic examination and are receiving support from the victims' assistance association. The case has been filed under organized gang kidnapping and extortion and is being jointly investigated by the regional judicial police and the French Cybercrime Office.France is the country most severely affected by such "ransom attacks" globally. Records from the national prosecutor's office for organized crime show that over 70 kidnapping and illegal detention incidents related to cryptocurrency have occurred in the first eight months of 2026, with 88 people already prosecuted in earlier crackdowns this year. Previous similar cases often targeted wealthy individuals, including the father of a cryptocurrency millionaire, the wife of a co-founder of The Sandbox, and the CEO of Binance France, while the victim in this case is merely an ordinary IT professional. Chainalysis reported that global ransom attacks in 2026 resulted in approximately 30 million dollars in losses, while CertiK stated that losses over six months reached 124 million dollars, a 12-fold increase.

first_img Chamath: The open-source weighted model is about four months away from the best closed-source frontier model

Social Capital founder Chamath Palihapitiya released an in-depth research report stating that open-source weight models are about four months away from matching the best closed-source frontier models in public evaluations, with increasing fluctuations in the gap. If open-source models allow companies more control over data, infrastructure, and customization while approaching frontier performance, the value corresponding to companies still paying for frontier laboratories becomes a business issue. Openness exists on a spectrum, from fully open-source models that can be downloaded and freely modified to open-source weight models with various restrictions, while closed-source models keep weights proprietary.Palantir CEO Alex Karp warned that companies might hand over differentiated proprietary knowledge and processes to frontier model providers. Microsoft CEO Satya Nadella stated that companies are effectively paying for intelligence twice: once in money and again in the more valuable proprietary knowledge that must be disclosed to make the intelligence useful. Despite concerns, companies are still willing to pay for frontier performance, even if the best open-source weight models are only months behind, with frontier laboratory revenues continuing to accelerate.Leading companies use both types of models, leveraging open-source models for control and customization while utilizing closed-source frontier models for maximum capability, with some cases reporting up to 12 times engineering efficiency and over 20 times cost savings. Some vendors adopt a dual-track approach, with Google offering both Gemini and Gemma, and Meta providing both Muse Spark and Llama. The 99-page report also discusses the costs of maintaining a lead for frontier laboratories, five factors of model competition, model operating locations, and investments in open-source weights by NVIDIA and Samsung.
