US economist Timothy Peterson warns markets are underpricing rapid Federal Reserve rate cuts, predicting a "surprise effect" that could jolt Bitcoin and altcoins upward within 3-9 months. Following the Fed's anticipated 25 basis point cut on September 17, 2025—to 4.1%—BTC hit $117,000 briefly before settling at $115,570 (+1.03% in 30 days). A 91.9% chance of another cut looms October 29; lower rates boost risk assets like crypto.
