This makes sense. Although the presidential term is only 5 years but if Trump starts this step from the beginning I think it will have a good impact on the US economy in the future. Also, by converting gold reserves into bitcoin, the impact on the national balance sheet will be quite neutral and of course it will not affect the fiat dollar because the exchange of gold to Bitcoin is completely independent of existing US financial assets.
The term of the US president is 4 years, not 5 years.
Using bitcoin as a reserve will not have a significant impact on their economy because national reserves are only used in emergencies, not in a healthy economy.
Trump will change domestic policy, foreign policy, tax policy, immigration policy...all of these factors are key to determining the US economy, not relying on national reserves.
Also, President-elect Trump also likes the concept, and he himself has shown interest in Bitcoin reserves. He sees it as an investment that can theoretically increase in value in the long run and help reduce the national debt. The idea should be brought to congress next year to create a strategic Bitcoin reserve for the US, if this can be done then the goal of collecting 1 million Bitcoins will be easy to achieve.
Using bitcoin to replace gold in strategic reserves will not affect the strength of the USD because we are no longer on the gold standard. But bitcoin's volatility needs to be taken into account as it is not always beneficial, so it needs to be carefully considered as it will directly impact the value of the strategic reserve asset.
Trump also made this proposal during his campaign but honestly, we are not even sure that he will keep his promise, let alone expect him to fulfill every promise. We need to know that politicians are not trustworthy and Trump is no exception.
Also, I don't think the proposal to sell gold to buy bitcoin will be easy to pass because competitors in the US are actively buying gold, they can't sell gold. This is very risky and not in their favor. Meanwhile, raising 100 billion to buy 1 million bitcoins (current price) is not easy, I don't think the government will have enough budget to do this if the gold sale is not approved.
