The reserves are established
President Trump has signed an executive order establishing a Strategic Bitcoin Reserve for Bitcoin and a U.S. Digital Asset Stockpile for Altcoins, which will be overseen by the Treasury Department.
I am convinced (DYOR) the Bitcoin reserve is serious, and the stockpile was created solely to assist with assets.

The sources for the US crypto reserves
The source of the reserves is yet to be determined. Taxing individuals for the government's Bitcoin is a bad idea in my opinion because it would just enrage the cryptocurrency community.
For now, assets seized through criminal or civil asset forfeiture actions will be added to both reserves, and potential sources of more bitcoins will be investigated without burdening taxpayers.

US might Trade alts for more Bitcoin
The US Bitcoin reserve has been established as a store of value for the United States, therefore selling bitcoin from this reserve is illegal.
However, the digital asset from stockpile are allowed to be sold as needed. Hence, it is easy to imagine that the US will obtain more Bitcoins by selling assets from the stockpile.
