2025 could be "worse than the dot-com bust", says man who predicted 2008 banking crisis (Ad)

What's coming next to the U.S. market could be worse than anything we've ever seen before – worse than the dot-com bust, worse than the COVID crash, and even worse than the Great Depression. What's coming, he says, could soon crash the market by 50% or more – and keep it down for 10, 20, or even 30 years.
