Bitcoin falls below $81,000 amid Fed rate hike uncertainty after hotter U.S. inflation data

Bitcoin fell below $81,000 after U.S. inflation data showed consumer prices rose 3.7% in the 12 months through September, exceeding expectations and reviving concerns about a Federal Reserve rate increase in October. Market odds for an October rate hike initially spiked near 50% but settled around 26% to 30%. This uncertainty, coupled with $150.5 million in U.S. spot bitcoin ETF outflows on Oct. 14, is weighing on liquidity and risk appetite, also causing global stocks like KOSPI to plunge 8%.
