Jack Dorsey Announces Bitchat Messaging App
Twitter co-founder and CEO of Block Jack Dorsey launched the beta version of a new peer-to-peer messaging app on TestFlight. Unlike WhatsApp and others like it that rely on internet connectivity and central servers, Dorsey says that Bitchat operates entirely over Bluetooth mesh networks, promising true decentralization and privacy for its users. He made "an ugly whitepaper describing protocol" available on GitHub.
CNBC broke down the tech and its features. In essence, Bitchat allows users to communicate via Bluetooth-connected devices. But here's where it gets interesting: "As users move through physical space, their phones form local Bluetooth clusters and pass messages from device to device, allowing them to reach peers beyond standard range — even without Wi-Fi or cell service."

Messages that are sent via Bitchat are encrypted from end to end and do not live in the cloud — they are only stored on devices and are set to delete. The message "never touch centralized infrastructure," reports CNBC, "echoing Dorsey's long-running push for privacy-preserving, censorship-resistant communication."
Dorsey's post on X has received over 1.3 million views, with beta testers eager to jump in. The TestFlight page is no longer available after hitting its 10,000-user maximum.

Intel announces more job cuts and drops projects in Europe in plan to save the company
Intel Corp. is shedding thousands of workers and cutting expenses as its new CEO works to revive the fortunes of the struggling chipmaker that helped launch Silicon Valley but has fallen behind rivals like Nvidia Corp. and Advanced Micro Devices Inc. In a memo to employees Thursday, CEO Lip-Bu Tan said Intel plans to end the year with 75,000 "core" workers, excluding subsidiaries, through layoffs and attrition. That's down from 99,500 core employees at the end of last year. The company previously announced a 15% workforce reduction. "I know the past few months have not been easy. We are making hard but necessary decisions to streamline the organisation, drive greater efficiency and increase accountability at every level of the company," Tan wrote. In addition, Intel will scrap previously planned projects in Germany and Poland and also move assembly and test operations in Costa Rica to larger sites in Vietnam and Malaysia. Costa Rica will remain a "home to key engineering teams and corporate functions," Tan said in the memo. Related Nvidia to sell H20 chips to China again after US gives export approval ASML sees share price drop as Trump's tariffs darken outlook In the US, the company said it will "further" slow construction of a semiconductor plant in Ohio. Founded in 1968 at the start of the PC revolution, Intel missed the technological shift to mobile computing triggered by Apple's 2007 release of the iPhone. Intel's troubles have been magnified since the advent of artificial intelligence — a booming field where the chips made by once-smaller rival Nvidia have become tech's hottest commodity. The Santa Clara, California-based company's market cap was $98.71 billion (€84bn) as of the market close on Thursday, compared with Nvidia's $4.24 trillion (€3.61tr). Tan said Intel is focusing on its "core product portfolio" and artificial intelligence offerings to serve customers better. "There are no more blank checks," Tan wrote. "Every investment must make economic sense." For the second quarter, Intel reported a loss of $2.9bn (€2.47bn), or 67 cents per share, down from a loss of $1.6bn (€1.36bn), or 38 cents per share, a year earlier. Excluding one-time items, the company posted a loss of 10 cents a share. Revenue was flat at $12.9bn (€10.1bn). Analysts, on average, were expecting adjusted earnings of 1 cent per share on revenue of $12bn (€10.2bn), according to a poll by FactSet. 擷取數據時發生錯誤 登入存取你的投資組合 擷取數據時發生錯誤 擷取數據時發生錯誤 擷取數據時發生錯誤 擷取數據時發生錯誤

‘Clearly Positive' S&P Listing Adds Weight of Expectation on Block Stock (XYZ)
Block Inc. (XYZ) stock has given bulls something to celebrate after its recent addition to the S&P 500 (SPX) this week, triggering a 10% surge on the day of the announcement. While this milestone lends credibility to the investment case, the long-term return potential appears less compelling from an organic growth standpoint. J.P. Morgan analysts have hailed the move as a 'clear positive' and are forecasting around a 24% upside over the coming year. Elevate Your Investing Strategy: Take advantage of TipRanks Premium at 50% off! Unlock powerful investing tools, advanced data, and expert analyst insights to help you invest with confidence. I remain Bullish on Block's digital payments ecosystem, but much of the optimism already seems priced in. The current valuation assumes strong growth through 2026, leaving the stock vulnerable to downside volatility thereafter. Consensus forecasts project 40% normalized EPS growth in Fiscal 2026, with the rate slowing to around 20% by Fiscal 2027. Block Stock's Upside Is Limited by a Fair Valuation Block's forward revenue growth rate of 8% is slightly higher than the sector median of 6.5%, but way lower than Block's five-year average of 44%. However, to offset this discrepancy, management has maintained substantial diluted earnings per share growth recently, with forward growth of 28.5% compared to 35.5% as a five-year average. This relatively strong earnings growth presents a case for the stock being fairly valued right now, as its forward price-to-sales ratio of 1.93 is 32% lower than the sector median of 2.85 and 48% lower than Block's five-year average of 3.72. Additionally, when examining the technical charts, the stock price is currently positioned just above the 50-week moving average and is approaching the bottom of the 200-week moving average. With the 14-week Relative Strength Index ('RSI') at 60, this combination of technical signals shows that Block is very reasonably priced, given that forward growth is expected by consensus to be quite strong. Watch for Earnings Catalysts to Sustain Sentiment Block is set to report its Q2 results on August 7, and investors should pay close attention to key metrics such as re-acceleration in gross payment volume (GPV), Cash App monetization trends—particularly average revenue per user—and management's outlook for second-half growth. In Q1, Cash App likely had around 57 million active users, roughly flat year-over-year. However, gross profit grew 10% YoY, with gross profit per monthly active user up 9%. Meanwhile, the Square ecosystem—which serves business and professional users—posted a 7.2% increase in GPV, with international volumes surging 15% YoY. If similar momentum is carried into Q2, Block's valuation could remain elevated, particularly in light of its recent inclusion in the S&P 500 (SPY). That said, Block has missed consensus EPS estimates for three consecutive quarters. With the S&P-driven sentiment boost now priced in, another earnings miss could spark a pullback in the stock. Fundamentals Reveal a Healthy Company Worth Long-Term Holding When evaluating an investment, it's essential to look beyond short-term price fluctuations and sentiment-driven events, such as earnings announcements or news headlines. The most compelling opportunities are rooted in a thorough understanding of a company's financial health and its impact on ongoing operations. Block's balance sheet reflects a strong foundation, with $7.5 billion in cash and short-term investments reported most recently—giving the company significant flexibility to pursue growth initiatives. It also holds total equity of $21.44 billion, against total assets of $36.4 billion and total liabilities of $14.96 billion. This healthy capital structure suggests that the company is not overly burdened by debt, which improves its prospects for stable net income and smoother long-term growth. Block's net income has been anything but consistent over the past decade, but that trend appears poised to shift. The company reported $166 million in net income for Fiscal 2021, followed by a $541 million loss in Fiscal 2022. However, it has since rebounded sharply, posting a substantial $2.615 billion net profit over the last trailing 12 months. With the company now operating at a larger scale and holding a more substantial market share after years of aggressive expansion, a more sustained margin trajectory seems likely. While short-term volatility may persist, the risk of significant losses going forward appears much lower. Is XYZ a Good Stock to Buy? On Wall Street, XYZ stock carries a Moderate Buy consensus rating based on 28 Buy, six Hold, and two Sell ratings over the past three months. XYZ's average stock price target of $73 implies approximately 8.5% downside potential over the next twelve months. Essentially, this can be due to a fair valuation and the fact that the company is facing lower revenue growth than historically, with a likely moderation in its normalized earnings per share growth in Fiscal 2027. As the market typically prices stocks according to fundamentals a year in advance, it makes sense why Wall Street views XYZ with some skepticism right now. XYZ Uptrend Remains Intact Despite Short-Term Volatility I remain long-term Bullish on Block, though some short-term volatility is likely. Existing investors may consider holding or even increasing their positions, while prospective investors should carefully assess their risk tolerance and investment horizon before jumping in on XYZ. From a technical and fundamental perspective, the stock appears fairly valued, but it could face downside pressure over the next 12 months as earnings growth moderates following sentiment-driven gains from its inclusion in the S&P 500. Still, short-term pullbacks or sideways movement don't rule out the possibility of the stock surpassing $100 in the coming years. It's a solid investment—but not a top-tier pick at this stage.
