Harry Dent, founder of HS Dent Investment Company, has issued a stark warning about a potential market crash in 2026, which he predicts could be the worst since the Great Depression. Dent suggests that a 17-year financial bubble is set to burst, potentially leading to a 90% decline in stocks, real estate, and digital assets. He identifies early 2026 as a critical period, suggesting that U.S. Treasury bonds might be the only safe investment. Dent's forecast stands in contrast to Peter Schiff's prediction of a U.S. dollar collapse. The anticipated market downturn could place significant pressure on altcoins, which may struggle if the bubble deflates as predicted.
