LEDGER HARDWARE WALLET IMPLANTS WERE DISCOVERED OVER A YEAR BEFORE THIS WEEK’S SUPPLY-CHAIN ATTACK REVELATIONS Renowned hardware security researcher and computer engineer Joe Grand (Joe Grand), also known as “Kingpin,” explains how he was contacted in August 2025 by a man in Thailand who had discovered a compromised Ledger Nano X. The man had purchased a cheap Ledger online to replace the battery in his existing device. When he opened it, he discovered a smaller battery, unauthorized circuitry, additional wiring, and an antenna. After posting his discovery on Reddit and reportedly receiving little interest from local police, he contacted Grand to investigate. The discovery came more than a year before the Ledger supply-chain attack became a major public controversy, with nearly $100 million in cryptocurrency reportedly stolen this week.

NEW: Dutch Parliament Member Michel Hoogeveen explains how the 36% unrealized capital gains tax, just passed by the House of Representatives, will work. Here is a more detailed example: Step 1. Starting position You own 500 shares. Value on Jan 1, 2028: €50,000 Value on Jan 1, 2029: €100,000 So the paper gain is: €100,000 − €50,000 = €50,000 unrealized profit You did not sell. But for tax purposes, that €50,000 is treated as income. Step 2. Apply exemption You are married, so you get a €3,600 exemption. €50,000 − €3,600 = €46,400 taxable amount Tax rate: 36% €46,400 × 36% = €16,704 tax bill That bill is due in May, even though you never sold anything. Step 3. Market falls before you pay Now suppose by May the shares drop in value. New total value: €60,000 So your portfolio is no longer worth €100,000. It’s worth €60,000. But the tax bill is still €16,704, because it was calculated based on the January 1 valuation. Step 4. You must sell shares to pay tax To raise €16,704, you sell part of your shares. After paying the tax, you’re left with: €60,000 − €16,704 = €43,296 Originally you had 500 shares. Now you have 360 shares left. You were forced to sell 140 shares. 140 ÷ 500 = 28% of your shares gone. Step 5. What happened economically? Before the correction: Paper gain was €50,000. After the correction: Portfolio is worth €60,000. Original cost basis was €50,000. Real gain is only €10,000. But you paid €16,704 in tax. So instead of being up €10,000, you are now: €43,296 − €50,000 = €6,704 below your original starting value. You turned a €10,000 real gain into a €6,704 net loss. And you lost 28% of your shares permanently.

WARREN BUFFETT STEPS DOWN AFTER 56 YEARS, LEAVING BEHIND A WARNING ON CURRENCY DEBASEMENT “Father Time always wins.” Warren Buffett has stepped down as chairman of Berkshire Hathaway, ending a 56-year run at the helm of the company. The 96-year-old will remain on the board as chairman emeritus, with his son Howard Buffett taking over as chairman. In one of Buffett’s final years running Berkshire, he warned that the biggest long-term threat investors face is something they cannot escape, currency debasement. “The tendency of a government to want to debase its currency over time… there’s no system that beats that.” “The natural course of government is to make the currency worthless over time.”

🇪🇺 EU PRESIDENT URSULA VON DER LEYEN SAYS EUROPE MUST PUT PEOPLE’S SAVINGS “AT THE SERVICE OF ITS COMPANIES” Von der Leyen says €10 trillion in European household savings are "lazy" because they remain in bank deposits, while a significant portion is invested outside Europe. She says the EU has put forward proposals on securitization, bank and insurance investments, market integration and supervision, which could unlock up to €470 billion in additional investment. European leadership has an eye on the savings of individuals. h/t Tablesalt 🇨🇦🇺🇸
