Bitcoin Plunge as Treasury Cuts Bailout Outlook; BTC-USD Dips to $73K, ETH Also Falls

Bitcoin (BTC-USD) plunged 2% to about $73,000 on February 04, 2026, amid Treasury Secretary Scott Bessent’s声明 that the U.S. Treasury lacks authority to buy or bail out cryptocurrencies. The hearing underscored the administration’s non-intervention stance, exacerbating broader sell-off pressure. Supporting context: The rout continued through October 2025, with BTC-USD down 13% over the past five trading days and hitting its lowest level since April. Ether (ETH-USD) and other digital assets also declined. With key support at $73,000, 10X Research said sentiment had shifted sharply and positioning suggested investors were deleveraging rather than buying the dip. Fundstrat’s Sean Farrell noted the mid-$70,000 area as a potential support zone but warned conditions remain trending lower, with traditional market positioning risk lingering.
