Honestly, I am sure that it has helped them a bit, because their investment grew, they got in at a lower price, now have more money, that's a benefit isn't it? Secondly, it "can" create jobs, depending on which nation we are talking about. Of course El Salvador wasn't seen as prime location, but if it was, every big crypto company would open their headquarters there, and hire people to work there instead.
But, El Salvador wasn't big enough or good enough to attract companies like that. At the end of the day, if USA makes it legal tender one day, which isn't impossible if you ask me, could happen in the future, then we could see a lot more stuff changing and then it could help a lot of people without a doubt.
El-Salvador has made huge profits from its investment and it can be said that they have benefited from investing in bitcoin. But that doesn't mean bitcoin played a major role and helped them improve their economy. They never even sold any bitcoins, they just bought and bought from 2021 till now, how can say bitcoins are helping them improve the economy when they never used them?
If government can convince and attract crypto companies to invest in their country and create jobs for the people. That means their government is the one that creates jobs and improves people's lives. Like you and me are participating in forum signature campaigns and we get paid by businesses, and bitcoin is used as a means of payment. It is clear that businesses and forums are paying us, not in bitcoin or crypto.
In short, bitcoin is just money and to earn money we need to work. Bitcoin is not a company, a business...how can it create jobs?
