first_img Castle opens Bitcoin savings stack to individuals, with dividends redeemable for Bitcoin at any ratio

According to Bitcoin Magazine, the Bitcoin fintech company Castle announced that it will open its automated Bitcoin financial stack to individual users and launch a pioneering feature in this category: users can choose to receive dividend income in cash or Bitcoin at any ratio.Castle's revenue comes from the perpetual preferred stock STRC issued by Strategy, which was incorporated into the platform earlier this year and currently pays an annualized dividend of 12% on a semi-monthly basis. Users can receive 100% of the dividends in cash, convert 100% to Bitcoin, or choose any ratio between the two. According to the company, most users opt for a compromise solution, using cash to cover daily expenses while automatically reinvesting the remaining portion into Bitcoin with each dividend payout.Castle co-founder and CTO João Almeida stated that investors have long faced a dilemma of choosing between stable income and holding Bitcoin. Castle allows users to achieve both cash flow and long-term upside by automatically converting a portion of the dividends into Bitcoin. Previously, Castle only catered to business clients such as restaurants, gyms, accounting firms, and e-commerce; the opening of personal accounts was due to repeated requests from business owners. Castle was co-founded by Almeida and CEO Stephen Cole and has received investments from Boost VC and Winklevoss Capital.

Gate Research Institute: In August, the overall risk assets increased, and the trend momentum strategy performed steadily

Gate Research Institute released the August 2026 cryptocurrency and TradFi quantitative report. BTC and ETH rose approximately 25.1% and 32.6% respectively during the month. Gate contract data shows that the open interest amount for BTC increased from about $4.02 billion to $4.38 billion, while ETH rose from about $2.46 billion to $2.75 billion, with increases of approximately 9% and 12.1% respectively.The funding rates for both remained moderately positive most of the time, with long positions dominating the number of accounts, but the active trading long-short ratio was below 1. The TradFi market also rose in sync, with NAS100 increasing about 4.2% during the month, outperforming US500 and US30, while large tech stocks showed a divergence in trends.The report compared four models: moving average trends, trend momentum, Donchian breakout, and RSI mean reversion. Backtesting results showed that the 100-day moving average and 20-day price momentum strategies achieved positive cumulative returns on BTC, ETH, US500, and NAS100, with a median Sharpe ratio of 0.64 and a median maximum drawdown of 8.71%. The report includes Gate TradFi's US500 and NAS100 in cross-asset observations and evaluates market heat by combining Gate contract long-short ratios, funding rates, and open interest data. The execution over the next one to three months will focus on trend confirmation, volatility rebalancing, leverage limits, and cooling off abnormal liquidations.

first_img Google claims that the cost of AI server memory has exceeded 75%, promoting a dual-track strategy for software and hardware

The SEMICON Taiwan 2026 Memory Summit took place on the 1st, where Nikhil Cherian, Senior Director of Supply Chain Infrastructure at Google Cloud under Alphabet, pointed out that with the popularity of multimodal and mixed expert architectures, AI computation has shifted from being power-limited to memory-limited, with high-performance memory accounting for over 75% of the cost of AI server hardware bill of materials. In the face of capacity, bandwidth, and power consumption bottlenecks, Google is breaking through the AI memory bottleneck through a dual-track strategy of hardware offloading for inference and training, and lossless quantization software algorithms.Google adopts an offloading strategy in hardware architecture, launching TPU 8i for low-latency inference and TPU 8t specialized for large-scale training. The TPU 8i is equipped with 288 GB of high-bandwidth memory, with SRAM capacity on the chip increased threefold to 384 MiB, placing dynamic conversation states and key-value caches on the chip itself to achieve zero chip-off latency. The TPU 8t forms a super-large computing cluster with 9600 chips, achieving a shared pool of HBM at a scale of 2 PB, eliminating chip-off data transfer bottlenecks, along with TPU Direct Storage technology.Google has developed the training-free TurboQuant lossless quantization algorithm, compressing the key-value cache of large models from 32 bits to 3 bits, reducing memory usage by six times without loss of accuracy, resulting in an eightfold acceleration in attention computation, and integrating old-generation DRAM technology to extend the lifecycle of components.
