Basically you need to be rich in order to move to El Salvador.

I would advise moving to El Salvador unless you have a government pension like this Canadian lady. Wages are too low in El Salvador, you are better off working in the US, saving in Bitcoin, get the government pension then someday you can move to El Salvador. Which is what that lady basically did.
