Bitcoin has surged to a new all-time high of $126,000 in October 2025, fueled by robust institutional demand and favorable regulatory conditions. The cryptocurrency's rise is significantly influenced by strong ETF inflows and macroeconomic trends, with the U.S. Federal Reserve playing a pivotal role in shaping investor behavior. Paul Howard of Wincent highlighted the anticipated Q4 rally, attributing it to U.S. stimulus measures. Major exchanges and ETF providers have been instrumental in attracting investment, while on-chain data indicates a supply-demand imbalance that supports the elevated prices. Historical Q4 patterns suggest continued bullish trends for Bitcoin and altcoins like Ethereum.
