For sure there will be resistance but there are many followers who may consider the mindset that Trump is trying to implement and I am sure there will be many future presidents who will try to adopt Trump's steps when the election comes.
Some say this is just a promise because it may not see much implementation for a planned agenda but when it does work then there will be greater adoption for other country leaders.
El Salvador may be the state that has made a big move on bitcoin and they are a great example of why bitcoin can be so useful for growth even though it does not implement a direct reserve pattern.
Then there is the analysis of economic growth for other countries by making the difference that El Salvador has achieved itself so that the conclusions that he will take based on other steps forward.
