A prominent trader notes that Bitcoin has a strong buy wall at the $80,000 level; if the current price can stabilize, it is worth going long.

In response to the incident where Ledger devices sold via the CryptoBilis channel were suspected of being tampered with, leading to the theft of approximately $90 million in assets, OneKey founder Yishi stated in a post that as of October 10, OneKey had not received any related damage reports. After conducting an in-depth analysis of the attack path of the implant attack in Ledger's hardware supply chain, OneKey announced five improvement measures: upgrading anti-counterfeit packaging, launching a screen-free initialization process, and advancing encryption for internal motherboard bus communication at both firmware and hardware levels, among others. Yishi expressed hope that manufacturers, researchers, and distribution partners will collaborate closely, noting that all parties need to carefully study how devices reach end users and how sensitive data is transmitted internally within devices.

According to an official announcement, HyperEVM-based synthetic perpetual protocol Papertrade is set to officially launch trading at 22:00 tonight. Deposits will be suspended at 13:45 UTC, 15 minutes before launch, to ensure transactions receive top priority during the rollout. Per the protocol’s official website, pre-deposits have exceeded $90 million, with 7,280 addresses participating. The team opened pre-deposits on the 9th, noting that account creation and deposits will be significantly throttled once trading goes live. Pre-depositing helps avoid launch congestion, though there are no additional perks for early deposits during the pre-deposit window. Papertrade is a fully on-chain synthetic perpetual trading platform built on HyperEVM. It pulls prices from the BBO mid-price of Hyperliquid’s order book, with users trading directly against the protocol’s liquidity providers (LPs) rather than relying on traditional order book matching. Key features include high leverage, zero slippage, and no funding fees. Its native token PAPER has an initial supply of zero, with no pre-mining, team, or VC allocations. The only source of token minting is user losses or liquidations. During the initial launch phase, the token cannot be freely transferred and is primarily used for staking.

Beating AI Express News reports that Nvidia may discontinue its most powerful consumer-grade graphics card, the RTX 5090, reallocating its core GB202 chips to higher-priced professional GPUs. Hardware leaker MEGAsizeGPU states all future production of the GB202 chip will be supplied exclusively to the RTX PRO series, no longer used for the RTX 5090. Another leaker, hongxing2020, shared what appears to be an internal factory notice, noting the China-exclusive variant of the RTX 5090 is also included in the discontinuation plan. The two graphics cards use the same family of GB202 chips but have drastically different price points. The RTX 5090 comes with 32GB of VRAM, launching at $1,999. The RTX PRO 6000, targeted at AI development, design, and rendering workloads, boasts 96GB of VRAM and is priced at $16,000 on Nvidia’s official website — eight times the cost of the RTX 5090. While price alone does not directly equate to profit, the high-end professional market clearly offers Nvidia far greater revenue potential. The RTX 5090 has already faced significant stock shortages in the U.S. market, with some third-party sellers even listing units for $9,600. If the discontinuation is confirmed, consumers will only be able to access remaining inventory moving forward. A more impactful change could be a step backward in GeForce flagship performance. Another leak claims Nvidia plans to launch a 24GB version of the RTX 5080, which will replace the RTX 5090 as its top-tier gaming graphics card. The current RTX 5080 has roughly half the number of CUDA cores as the RTX 5090, delivering around 30% lower 4K gaming performance. Even if the new model’s VRAM is increased to 24GB, it will still lag behind the RTX 5090’s 32GB of VRAM.

According to Salus monitoring, the attacker behind the Triple-A breach has transferred 4,970 ETH to Tornado Cash, worth around $12.4 million. The attacker routed two separate fund streams through a single wallet, depositing the funds into Tornado Cash via 49 transactions of 100 ETH each and 7 transactions of 10 ETH each. One of the streams includes funds that were previously withdrawn from a mixer. On July 27, stablecoin payment infrastructure Triple-A was hacked, with total losses totaling approximately $11.8 million.
