I guess this is a revolution against USD.
El Salvadorian president, Nayib Bukele is not specific about dollar, he generalized it on fiat, not United States Dollar. This is the tweet from the president:
W
hat has been called by international organizations as “The #Bitcoin Experiment”, is nothing more than the world watching how mass adoption changes a country’s economy.
If it’s for the good, it’s game over for FIAT.
El Salvador is the spark that ignites the real revolution.
The president did not mention anything related to what is in the OP, I think it is just how news can make it misleading by nothing convey the actual fact.
Taking the title from the news site as an example:
El Salvador President says Dollar is dead, Bitcoin is futureAlso from the same site, I quote:
By directing his comments at fiat currency in general, Bukele has raised a question on the future of the existing physical currencies around the world. The president just tweeted about fiat generally. But it is obvious that the fiat will survive as bitcoin is just an alternative. I think it is only just about awareness than what the tweet actually meant.
