And again when the current president of US, Mr. Trump had embraced Bitcoin and announced it as a strategic reserve, countries that patronize the dollar might not see any need for that anymore. At least we already know that the China and Russia agreement was not in dollar. So as the users (Countries) of dollars begin to think deeper regards making bitcoin a strategic reserve, they might give an interpretation that might not make them keep dollar as there reserve because many countries reserve there money in dollar, also cost and value it in dollar. Therefore making agreement to use bitcoin for bilateral transactions and dollar would begin to lose value.
