Bitcoin fell ahead of the US market open following a three-day break, tracking weakness in equity futures as investors returned to a more cautious macro backdrop.
The token dropped as much as 1.7% to $67,6586 on Tuesday. Nasdaq 100 futures slid 0.9% and S&P 500 contracts lost 0.6%, signaling a softer start on Wall Street. Bitcoin, which has traded like a high-beta tech proxy in recent months, mirrored the move lower.
