2. Kalshi Co-founder Lara: From Professional Ballet Dancer to World's Youngest Self-Made Female Billionaire

Luana Lopes Lara graduated from MIT with a degree in Computer Science. During summer breaks from college, she worked at Ray Dalio's Bridgewater Associates and Ken Griffin's Citadel Investment Group, building an $11 billion startup in just six years. However, this Brazilian-born girl still calls high school "the most stressful years of my life." At the Bolshoi Theatre School in Brazil, her ballet teacher would place a lit cigarette under her thigh and make her stretch her leg to her ear—a test of how long she could lift her leg without getting burned. To get ahead, classmates would hide shards of glass in each other's shoes. The fierce competition also required her to attend academic classes from 7 am to noon and ballet classes from 1 pm to 9 pm.

3. In-depth analysis of the Ethereum Fusaka upgrade: core changes and ecological impact

Ethereum plans to conduct its next upgrade on December 3, 2025 at 21:49 UTC (slot 13,164,544), a hard fork known as "Fusaka". Fusaka combines the execution layer upgrade "Osaka" and the consensus layer upgrade "Fulu", following the naming conventions of previous forks.

4.2026: The Year of Regime Change at the Federal Reserve

The Federal Reserve as we know it will end in 2026. The most important driver of asset returns next year will be the new Federal Reserve, especially the regime change brought about by Trump's new Fed chairmanship. Hassett has become Trump's top choice to lead the Fed (Polymarket's probability is 71%). Currently serving as director of the National Economic Council, he is a supply-side economist and a long-time staunch supporter of Trump, advocating a "growth first" philosophy. He believes that maintaining high real interest rates is political obstinacy rather than economic prudence, given the basic victory in the war against inflation. His potential appointment marks a decisive regime change: the Fed will shed the technocratic caution of the Powell era and shift to a new mission that explicitly prioritizes lowering borrowing costs to advance the president's economic agenda.

5. What will the Fusaka upgrade bring to Ethereum

The name Fusaka comes from a combination of the execution layer upgrade Osaka and the consensus layer version Fula Star. This upgrade is expected to be activated on December 3, 2025 at 21:49 UTC. This upgrade includes 12 EIPs, covering data availability, Gas/block capacity, security optimization, signature compatibility, transaction fee structure, etc., and is a systemic upgrade that achieves L1 scaling, reduces L2 costs, reduces node costs, and improves user experience.
