The reserve will be capitalised 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 on Thursday.
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. Sacks said the federal government will have a strategy to maximise the value of its holdings in such a reserve, without offering details.
"The US will not sell any bitcoin deposited into the Reserve. It will be kept as a store of value. The Reserve is like a digital Fort Knox for the cryptocurrency often called 'digital gold'," Sacks said.
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 de-legitimising the digital currency industry.
Proponents argue that a reserve would help taxpayers benefit from crypto's price growth.
Trump's executive order directed the secretaries of Treasury and Commerce to develop "budget-neutral strategies" for acquiring additional bitcoin that have no "incremental costs" on taxpayers.
Sacks estimated the US government owns about 200,000 bitcoin and premature sale of the cryptocurrency has cost the American taxpayer $US17 billion ($A27 billion). It wasn't clear how Sacks arrived at these estimates.
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.
