April 3 (Reuters) - U.S. crypto stocks declined in premarket trading on Thursday after President Donald Trump's latest round of sweeping tariffs rattled investor confidence due to rising global trade tensions, sparking a sell-off in riskier assets.

Crypto exchange Coinbase Global COIN.O fell about 4%, while major bitcoin holder Strategy MSTR.O dropped 3%. Among miners, MARA Holdings MARA.O, Riot Platforms RIOT.O and Bitfarms BITF.O slipped about 4%, 5% and 6%, respectively.

The broad losses underscore the widespread fallout of the tariffs on multiple asset classes. Bitcoin BTC=, the biggest cryptocurrency, dropped 2.3%, while ether ETH= dived 3.3%.

Even though the Trump administration has signaled a willingness to embrace crypto and adopt a lighter approach to regulation, broader economic instability tied to the sector could still impact companies.

Still, some analysts said the moves were less severe than other industries.

"The price action highlights crypto's hyper-democratic and borderless nature, allowing investors worldwide to hedge against the potential impact of macroeconomic uncertainties," said David Hernandez, crypto investment specialist at 21Shares.

Crypto exchange traded-funds may also attract some inflows from retail investors who will be hunting for opportunities, according to Marco Iachini, senior vice president of research​​ at Vanda Research.

However,​​ he said the size of the flow could reduce as things get a bit shaky.
