On August 13, CryptoQuant analyst Axel Adler Jr. pointed out that the proportion of Bitcoin miners' fee revenue has dropped to 0.71%, nearing the historical low of 0.69% recorded in December 2015, when the BTC price was approximately $394. The 7-day moving average of the total network hashrate has decreased by 23% from its peak in October 2025 (around 1,150 EH/s) to 886 EH/s, while the BTC price fell from $124,700 to $63,400 during the same period, a decline of 49%. Since mid-2025, the fee revenue proportion has consistently hovered around or below 1%, indicating weak competition for block space, with miners' income almost entirely reliant on block subsidies. The analyst noted that while the fee revenue proportions in both periods are similar, they cannot be directly compared—block rewards in 2015 were 25 BTC, whereas they are now 3.125 BTC, making historical comparisons limited to revenue structure. The current situation resembles a controlled adjustment within the mining industry rather than a capitulation; a rise in the fee revenue proportion above 1% and a sustained upward trend in hashrate would signal a true change in the environment.

On August 13, in response to the HLP yield approaching zero, Hyperliquid founder Jeff stated on social media that in the next network upgrade, HLP will begin to automatically rebalance underutilized USDC to its lending sub-strategy. Jeff mentioned that the portfolio margin and borrowing/lending operations have reached production scale, having been tested in practice and supporting a considerable Total Value Locked (TVL), with demand continuing to grow. Additionally, the order book liquidity has matured to a certain extent, making HLP's liquidity no longer necessary in large-scale scenarios. Therefore, in the next network upgrade, HLP will start to automatically rebalance underutilized USDC to the lending sub-strategy.

According to monitoring by Beating, Anthropic has upgraded the sidebar of Claude in Chrome to a complete Claude Cowork session. Now, sessions are directly saved to the account, allowing users to start working in the browser and continue on desktop, web, or mobile. Claude in Chrome can also directly utilize Cowork's skills, plugins, and connectors. It can read web pages, click buttons, input content, and fill out forms. When it comes to local files or requiring Claude to actively operate the computer, a connection to Claude Desktop is still necessary. In July, Anthropic expanded Cowork to web and mobile, and now has integrated the Chrome sidebar into the same cross-device session. Cowork has evolved from an independent desktop agent to a continuous working agent across browsers, computers, and mobile devices. The new sidebar version is currently available to Max and Team users, with Pro being rolled out in the coming weeks. Enterprise users will require admin activation.
