So why was the executive order Bizarre?
Because, in what one hopes was just a grammatical oversight, the subject of the email sent out to the media notifying of the cryptocurrency ban, was that it is an "Executive Order on Taking Additional Steps To Address the Situation In America." Only after reading the actual email was it revealed that the EO actually refers to Venezuela, prompting some commentators to note that "Trump hasn't yet succeeded in turning America into Venezuela."
The full executive order can be found at the following link, and is summarized as follows in Trump's letter to Congress:
TO THE CONGRESS OF THE UNITED STATES:
Pursuant to the International Emergency Economic Powers Act (IEEPA) (50 U.S.C. 1701 et seq.), I hereby report that I have signed an Executive Order with respect to Venezuela that takes additional steps with respect to the national emergency declared in Executive Order 13692 of March 8, 2015, and relied upon for additional steps taken in Executive Order 13808 of August 24, 2017. The Executive Order prohibits, as of its effective date, all transactions related to, provision of financing for, and other dealings in, by a United States person or within the United States, any digital currency, digital coin, or digital token, that was issued by, for, or on behalf of the Government of Venezuela on or after January 9, 2018.
