Bitcoin briefly sinks to $75,700 as Democratic sweep bets rattle markets

Bitcoin briefly fell to $75,700 as early U.S. midterm returns suggested Democrats could take both chambers of Congress. Stock futures and the dollar slid while Treasuries rallied, signaling a risk-off shift across markets. Traders care because a Democratic sweep could reshape fiscal and regulatory policy, and BTC's drop shows it trading in step with broader risk sentiment.
