Crypto trader Rune stated on platform X that the official documentation of PaperTrade has disclosed a "vulnerability" risk in the pricing mechanism at the protocol level. According to the screenshots of the displayed documentation, attackers can manipulate prices using the Best Bid and Offer (BBO) from the Hyperliquid order book. This risk involves unresolved price manipulation pathways, contract economic mechanisms, risk exposure control, as well as operational protective measures and permission management mechanisms.In addition, Rune also forwarded a tweet from community user boblob, which revealed that two wallets are suspected of actively exploiting "attacks" on the PaperTrade platform, causing a slight fluctuation of about 10-20 basis points in the ETH price on the Hyperliquid platform through trades totaling approximately 20 million dollars. Boblob further added that there are obvious issues with the current PaperTrade protocol that need to be fixed as soon as possible, or it may affect the long-term sustainability of the protocol.

Binance founder Zhao Changpeng released a simplified guide for cryptocurrency asset custody, suggesting that users match security measures according to their holding scale and technical capabilities, while focusing on three major issues: preventing asset theft, avoiding accidental loss, and planning for asset inheritance in advance.Regarding self-custody, Zhao Changpeng advised users to take measures such as storing private keys on offline devices, using reliable hardware wallets, verifying transaction addresses, and setting up multiple off-site backups. He also reminded users to avoid saving keys through photos or screenshots to prevent them from syncing to the cloud and causing leaks. In terms of asset inheritance, users should develop a secure recovery plan in advance, avoiding direct sharing of keys or storing recovery information in an unencrypted form. For centralized trading platforms, Zhao Changpeng suggested that users assess the platform's reputation, security capabilities, and business model, and strengthen account protection through measures such as independent email, strong passwords, two-factor authentication, hardware security keys, and withdrawal address whitelists, while also being vigilant against phishing attacks and API credential leaks.Zhao Changpeng further suggested that users should reasonably allocate assets between centralized trading platforms and personal wallets based on their technical capabilities, security management levels, and funding needs. Self-custody means that users need to independently bear the responsibility for private key protection and asset recovery, while custody by trading platforms involves platform credit and counterparty risk. Additionally, maintaining an independent wallet helps to ensure access to assets during maintenance or service interruptions on trading platforms.

According to the official website of the U.S. Securities and Exchange Commission (SEC), on October 9, 2026, the SEC officially sued Linqto's former executives William Sarris and Joseph Endoso, accusing them of committing fraud by selling equity in pre-IPO unicorn companies to retail investors through their online platform.Between 2021 and 2024, Linqto's subsidiary sold over $430 million in special purpose vehicles (SPV) to retail investors. The SEC accused the two of: falsely reporting prices below market value (with almost all being above fair value), falsely claiming that stocks were "sold out," pretending that prices were dynamically set by algorithms (when they were actually manually priced), and publicly claiming compliance while knowing they were violating regulations. Additionally, they were accused of illegally operating an unregistered investment company and selling unregistered securities to non-accredited investors.The SEC seeks to impose an injunction against the two, recover illegal gains and interest, impose civil penalties, and prohibit them from serving as executives or directors of public companies in the future. The case is being investigated by the SEC's San Francisco Regional Office, with assistance from the U.S. Attorney's Office for the Southern District of New York and the FBI.

Data shows that the cumulative trading losses of platform users reached 4.73 million USD.According to official documentation, the issuance model of the Papertrade token PAPER is such that for every 1 USD lost by platform users, the protocol mints a certain amount of PAPER according to a curve.

According to Hupzy, the current net exposure of hedge funds to the "Magnificent 7" in the U.S. stock market has risen to 22%, a record high, surpassing the peak of 21% on June 2024, and increasing by 7 percentage points since July of this year. In comparison, at the bottom of the bear market in 2022, this indicator was only 8%.The record-long positions reflect strong confidence from institutions in technology stocks, but it also means that trading may be overly crowded and does not necessarily indicate that the market will continue to rise. If the relevant investment logic changes, large-scale liquidations could trigger a sharp reversal and directly impact the perpetual contract market for the S&P 500 index; a decline in risk appetite may also further pressure Bitcoin.Additionally, the net exposure of hedge funds in the semiconductor sector is currently at 12%, slightly below the peak of 14% in June 2024, but significantly up from 2% at the beginning of 2025. Over the past three months, the increase in hedge fund exposure to the Magnificent 7 has been the largest since 2023.
