Bitcoin's market capitalization has surged by $124 billion since the beginning of October 2025, climbing from $2.276 trillion to $2.40 trillion as of October 3. The cryptocurrency's price has reclaimed the $120,000 mark, driven by strong institutional demand and favorable macroeconomic conditions, including the U.S. government shutdown. Notably, BlackRock's ETF attracted $446 million in inflows on October 2, while large holders acquired over 30,000 BTC within 48 hours.
