Bitcoin's price volatility increased, with the hourly volatility rate jumping from 2.5% to 5.8% within the first hour following the announcement (Source: Kaiko, 2025-02-26 14:30-15:30 UTC).

The increased volatility and trading volume suggest that traders were actively adjusting their positions in response to the geopolitical news, seeking to capitalize on price movements or hedge against potential risks. The on-chain metrics further supported this, with the number of active Bitcoin addresses increasing by 15%, from 800,000 to 920,000, indicating heightened market participation (Source: Glassnode, 2025-02-26 14:30-15:00 UTC).
