That is if the people buy bitcoin right now given how there's a lot of resistance to adopt bitcoin in the public there, I don't think that it's not good news but to the people that's using those, they're probably happy right now since the prices are OP has said, discounted.
There is a resistance by some people but that doesn't mean that everyone has a doubt about it. I mean if a politician is doing something, there is a 99% chance that they believe they would gain some votes for the next election, or at least keep their own voters happy, there are rarely ever a politician that does something knowing it would cost them too many votes.
It means that if president did this, then he knows that he will gain votes meaning there are more people who support it then who resist it. Of course, people who resist it would be heard more, because people who support it just goes lives their lives, whereas people who are against it will do protests and such to get to news, and since news are owned by super rich people who would be hurt by the financial fair play of crypto world, they are heard more as well. Long story short, people are happy that it is discounted, because most people in El Salvador is fine with it.
