American Express is nearing the top position in Berkshire Hathaway's portfolio, overtaking Apple due to significant sales of Apple shares and steady gains for Amex, which has outperformed Apple by 106% over the past 2.5 years. Berkshire's sale of three-quarters of its Apple holdings has narrowed the gap, and if further reductions occur, Amex could become Berkshire's largest holding. Meanwhile, Bitcoin has fallen below $79,000 amid market digestion of a silver sell-off, which saw spot silver plunge 28% to $83.45 an ounce and futures drop 31.4% to $78.53, marking the worst day since 1980. The cryptocurrency's decline follows President Trump’s selection of Kevin Warsh as Fed Chair, strengthening the dollar and reducing Bitcoin’s appeal as an alternative currency. Bitcoin's break below $80,000 signals a crisis of confidence in its stability, reflecting recent volatile market conditions. Warren Buffett remains optimistic about long-term investments despite market volatility, emphasizing that short-term declines, such as the recent 3% dips, present buying opportunities. Buffett advocates for a long-term perspective, stating that the 20- and 30-year outlooks for American businesses remain unchanged despite current market fears.
