Trump sells gold to buy Bitcoin, this is the same logic as Kennedy issuing "silver certificates", which is to want to control the circulating currency of the United States, and now who is in control is the Federal Reserve.
The Federal Reserve is an independent institution and has never listened to the U.S. president. If the U.S. president wants to use money, he still has to look at the Federal Reserve’s face. Everyone knows who is behind the Federal Reserve.
Lincoln and Kennedy both did this, but times have changed, and now technology has advanced to cryptocurrencies. This should also be a suggestion from Musk to Trump; the gold reserves can be controlled by the Federal Reserve. But cryptocurrencies, no matter how capable the Federal Reserve is, they cannot interfere.
This can be seen as Trump laying a good financial foundation during his presidency, so that when he needs money in the future, he can bypass the Federal Reserve.
Don't say cryptocurrencies are just digits; as long as there is a U.S. endorsement, they are hard currency. However, after Kennedy issued the "silver certificates", he successfully disappeared from the world; I wonder if Trump will follow the same path this time.
This revealed plan has also caused Bitcoin to skyrocket recently, with hundreds of billions of U.S. dollars pouring in, and the price is likely to rise significantly.
