The people of the country are not ready, the governments of the world are not supportive, and the IMF wants El Salvadore to reverse its Bitcoin legal tender. And El Salvadore, as an economy, is one of the poorest economies in Latin America. It had to happen.
What are you talking about? Are you merely assuming that OP is true? That bitcoin adoption in El Salvador actually failed rather than considering such statement as presumptive...
In other words, you sound like you are praying for the bitcoin adoption that took place in El Salvador to get reversed, and that wish seems unlikely.
So sucks to be stuck with such fantasies, no?
You might want to attempt to learn why bitcoin is valuable in a place like El Salvador rather than merely wishing that its adoption had not happened or that such adoption in El Salvador or otherwise could be undone.
