All this bill really does is consolidate govt-held BTC and other cryptos under an official umbrella of strategic reserve/stockpile, require that they hold it for 20 years (unless Treasury deems it "in the interests of the United States" to sell), and tasks Treasury with figuring out "budget neutral" ways to acquire more BTC. That's it. There is no authorization for budgetary purchases of BTC by the federal government. And thank god there isn't.
