The Biggest Bitcoin Recap of the Week 1. 🇺🇸 Fed Chair Powell turns dovish* What it means: Jerome Powell, the head of the U.S. Federal Reserve, hinted that they might stop raising interest rates, or may even lower them soon. Why it matters for Bitcoin: When interest rates are low, traditional savings become less attractive, and investors start looking at assets like Bitcoin to protect their wealth from inflation. Example: If you earn 1% from the bank but inflation is 3%, you're losing value. Many turn to Bitcoin as a hedge. 2. 🇵🇭 Philippines proposes 10,000 BTC strategic reserve What it means: The Philippines is considering holding 10,000 Bitcoin as part of its national reserve, like gold or foreign currency. Why it matters: It shows countries are starting to treat Bitcoin like a strategic asset, which increases global confidence in BTC. Example: Like how central banks hold gold to back their currency, the Philippines might do the same with Bitcoin. 3. 🇧🇷 Brazil holds first Bitcoin reserve hearing ($19B) 👀 What it means: Brazil’s government held a public discussion on possibly adding Bitcoin to its national reserves, discussing an amount up to 19 billion. Why it matters: It marks a serious step toward Bitcoin adoption at the country level, potentially setting an example for other nations in Latin America. 4. 🇭🇰 Ming Shing to buy 500M in BTC What it means: Ming Shing, a major Hong Kong-based firm, announced it plans to invest 500 million into Bitcoin. Why it matters: Big institutional investments like this show growing trust in Bitcoin as a store of value, not just speculation. Example: Large companies such as Tesla or MicroStrategy previously made similar moves, now Asia joins in. 5. 🇸🇬 Volkswagen SG accepts BTC & crypto What it means: Volkswagen Singapore now accepts Bitcoin and other cryptocurrencies as payment for cars and services. Why it matters: It shows real-world utility of Bitcoin is growing—beyond investment, people can now spend Bitcoin to buy products. Example: You can buy a new Volkswagen and pay directly with your Bitcoin wallet. 6. ⚡️ SoFi taps Bitcoin Lightning for remittances What it means: SoFi, a U.S. fintech platform, is exploring the use of the Bitcoin Lightning Network to make fast and cheap international money transfers. Why it matters: It gives millions of users access to low-cost remittances using Bitcoin technology, especially helpful in developing countries. Example: A Tanzanian in the U.S. could send money home instantly using Lightning, with no high fees like Western Union. 🔥 Bitcoin adoption is growing across governments, companies, and fintech. From remittances and reserves to real-world purchases, Bitcoin is being recognized globally as a serious financial tool. The future is orange 🟧.

∞ Happy Bitcoin Infinity Day! ∞ Bitcoin Infinity Day, celebrated every August 21st (8/21) , is a symbolic day in the Bitcoin community representing the concept of "infinite growth vs finite supply." It’s based on the idea that there will only ever be 21 million bitcoins, yet demand and use for it can grow infinitely across the world. Why August 21? - The "8" represents infinity (turn the number 8 sideways ∞). - The "21" represents the 21 million BTC hard cap. So 8/21 = Infinity / 21 million — a powerful reminder that Bitcoin is scarce , but *human creativity, innovation, and adoption are unlimited. What does it mean? It’s a day to: - Celebrate Bitcoin’s mathematical scarcity. - Reflect on Bitcoin’s future potential. - Promote education, adoption, and freedom. - Share Bitcoin with friends, family, and community. Examples of how people celebrate: - Sharing Bitcoin facts or memes. - Orange pilling a friend. - Making small BTC Lightning payments. - Supporting Bitcoin creators or merchants. - Joining meetups or online spaces. Bitcoin Infinity Day is not just about price — it's about principles, education, and the belief that Bitcoin can empower people everywhere. ∞/21M = Freedom for all. Happy Bitcoin Infinity Day!
