Some believe that the U.S. promotes Bitcoin to entice China into the game to eliminate its $36 trillion debt, but China has not fallen for it. Perhaps what the U.S. wants is for China not to recognize Bitcoin.
Because if China recognizes it, with only 21 million Bitcoins available, it won’t be enough to go around and will be marginalized by mainstream currencies. Only if China does not recognize it can the U.S. justify not involving China, pushing up Bitcoin, and at some point directly abolishing it, allowing the U.S. foreign debt to be eliminated at once and still make a profit, before returning to the dollar.
After all, the inherent value of Bitcoin is questionable, and encryption and secrecy are not absolute; any decryption is an upgrade against the encryption. Therefore, Bitcoin is just a string of numbers, with no value. Only by being recognized by the U.S. government can it survive as an attachment to the dollar, although it may steal the limelight from the dollar, it cannot shake the dollar's status.
