Robert Kiyosaki, the author of the book "Rich Dad Poor Dad," recently stated that the United States is facing an economic depression that could be more severe than that of 1929. He advises investors to protect their wealth by purchasing Bitcoin, gold, and silver. Kiyosaki believes that these assets will serve as a safe haven amid the uncertainty of the future economy. He points out that the current economic policies and the instability of the global financial system are the main reasons behind this prediction.
