Cryptocurrency prices jumped after Trump’s surprise announcement he wants the U.S. government to purchase and hold a variety of digital assets in a strategic reserve fund.

While it’s not known exactly what form such a strategic reserve would take, nor whether the government would seek to buy crypto for the stockpile with taxpayer dollars — a move that would theoretically require approval from Congress — blockchain enthusiasts cheered the news.

Donald Trump’s announcement that the US will include three lesser-known digital tokens in its strategic crypto reserve was greeted with skepticism in the industry, with investors questioning the project’s merits and the coins he selected giving up some of their initial gains from Sunday.
