U.S. President Donald Trump signed an executive order on Thursday to establish a strategic bitcoin reserve, a day before meeting with executives from the cryptocurrency industry at the White House.

The reserve will be capitalized with bitcoin owned by the federal government that was forfeited as part of criminal or civil asset forfeiture proceedings, the White House crypto czar, billionaire David Sacks, said in a post on social media platform X.

Attendees at Friday's White House crypto summit expect the event to serve as a stage for Trump to formally announce his plans to build a strategic reserve containing bitcoin and four other cryptocurrencies.

Earlier this week, Trump announced the names of five digital assets he expects to include in this reserve, spiking the market value of each. The five are bitcoin, ether, XRP, solana and cardano, the president said.

It is not clear how such a reserve would work or how it would benefit taxpayers.

Trump's moves to support the crypto industry, which spent millions backing him and other Republicans in the November elections, have drawn concern from some conservatives and crypto backers over giveaways to an already wealthy community and delegitimizing the digital currency industry.

Proponents argue that a reserve would help taxpayers benefit from crypto's price growth.

The president's support for the crypto industry has also sparked conflict-of-interest concerns. Trump's family has launched cryptocurrency meme coins, and the president also holds a stake in World Liberty Financial, a crypto platform.

His aides have said Trump has handed over control of his business ventures, which are being reviewed by outside ethics lawyers.
