U.S.-listed shares of crypto companies tumbled on Monday, mirroring a sharp drop in bitcoin as escalating tariff tensions and fears of a global trade war triggered a broad retreat from risk assets.

Crypto prices have plunged, and the US stock futures market has opened down, extending its losses into a third day as the tariff fallout continues.

Bitcoin prices ticked up Friday, reversing a slide that began when new tariffs were unveiled earlier this week.

After holding relatively stable during last week’s global market turmoil, cryptocurrencies have joined the sell-off. Bitcoin, the world’s most popular cryptocurrency dipped below $75,000 Monday morning before seeing a slight rebound.

The rapid drop shows that cryptocurrencies, which the president has promoted, are subject to the same market gyrations as any other risky asset.

Hedge funder Bill Ackman called President Trump's tariff plan "economic nuclear war" and urged a Monday pause.
