It will be more a fund to recover stollen billions:

The Secretary of the Treasury shall establish an office to administer and maintain control of custodial accounts collectively known as the “Strategic Bitcoin Reserve,” capitalized with all BTC held by the Department of the Treasury that was finally forfeited as part of criminal or civil asset forfeiture proceedings or in satisfaction of any civil money penalty imposed by any executive department or agency (agency) and that is not needed to satisfy requirements under 31 U.S.C. 9705

After the recovery they just can’t flood the market because it’d lose in value. They have to do it over certain time, hence “the reserve”.
