WASHINGTON (Reuters) -U.S. President Donald Trump has signed an executive order to establish a strategic reserve of cryptocurrencies by using tokens already owned by the government, disappointing some in the market who had hoped for a firm plan to buy new tokens. The announcement, made on Thursday ahead of a meeting with crypto executives at the White House later on Friday, sent the price of bitcoin down by around 5% to $85,000. A "Strategic Bitcoin Reserve" will be capitalized with bitcoin owned by the federal government that was seized 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.
