Robert Kiyosaki, author of 'Rich Dad Poor Dad', has issued a stark warning on X, suggesting that the "biggest bubble in history" is nearing its burst. He emphasizes that the question is not if, but when this will occur. Kiyosaki forecasts that a year following a "global financial crisis (GFC)" style collapse, gold could reach $35,000 per ounce, silver $200 per ounce, Bitcoin $750,000 per coin, and Ethereum $95,000 per coin.
