I understand. Risk is relative and not absolute, but I wouldn't like to miscalculate it too much.
That depends. "Risk" is a somewhat ambiguous word. Risk can be relative when you talk about cryptocurrency, but if somebody puts a bullet in your head (not such a strange occurrence in some countries), you're absolutely dead.
I disagree about emigrating being such a big step, and I lived in 4 different countries, so while I'm not an expert, I guess I know a thing or 2 about it.
Of course there are inconveniences associated with it. You need to adapt to a new culture, and, in your case, a new language, and Spanish isn't the easiest language to learn. But other than that, it's just a trip.
I am seriously considering the idea, but I'm also struck by a lack of interest from other bitcoin users and how that contrasts with their otherwise overwhelmingly positive reaction to the news. It seems to me related to the expected long-run performance of the bond(s). I made a specific thread for moving/settling issues in case it turns into a useful resource, if not by me perhaps by someone else.
So far my only feedback is shipping companies are unable or hesitant to provide service and have warned about risks of loss of/damage to items in transit and customs issues. Visas are available without reference to bitcoin by showing income of ~$24k p.a.
I honestly think this whole issue is being hyped up, and taken out of context. El Salvador accepted BTC as legal tender because its economy was in ruins, and there are real benefits when getting your own currency on the back of another, stronger one. It does have a price, though.
The issue with insecurity there is a very real one. One of the very first things I learned (and loved very much) about living in the US, was having the chance to trust other people, and have a generally laid back attitude. That doesn't happen in Latin America. Life is nowhere near as simple.
If you're dead set about emigrating, I'd recommend you look to go somewhere else. if you're dead set about going to El Salvador, I'd say go there for a couple of months, and check the place out. First, it's gonna be much easier for you to inquire about the legal requirements to move there once you're in country, and second, you'll be able to really get a sense of the place, see what you like, and ultimately make an informed decision.
Just to provide some background, I emigrated from Argentina to the US in 2000. Loved everything of it. Spent almost 13 years in the US, until I was deported in 2013. Then, in 2015 I went to Spain, having researched extensively online, and thinking everything would be like I had read on the Internet. Big mistake. Spain is a beautiful country, but it's not at all what I was expecting. So I came back to Buenos Aires and immediately, and relying solely on recommendations, I moved to Lima, Peru. Hated every minute of it. Lima is (no intention to offend anybody), about the shittiest city I've ever seen.
Now I'm back in Buenos Aires, daydreaming with getting out, this time for good. But I learned my lesson, I'm not flying blind anymore.
