Portugal has been extremely popular with the nomad community too. A good dozen of friends of mine have already moved there through NHR and lots more are in the works. There are also projects like rebase.co, which make things super easy to set up base in the country. It seems like it's getting to a point where Portugal so popular, it might steer people away from itself instead.
It's amazing that people within the country (I live in Portugal and am portuguese) mostly want to get out, and so many people seem to want to get in (to work outside). I genuinely don't 100% get it.
I speak Portuguese (Brazilian) but most Portuguese people in the cities all seem to speak good English. Portugal is beautiful, has temperate weather and long coastline, really good clean food (sopa de legumes, leitão, sardinhas, etc), friendly people and easy access to the rest of the EU. And unlike traditionally aspirational places like Italy or Spain which are harder to move to unless you have the right lineage (for getting a passport), Portugal is within reach of middle class Americans.
That said, I was told that salaries aren't high for locals. For what it's worth, most younger people in Italy and Spain don't think their economic life is all that great either. The money seems to be in northern/central Europe, i.e. well, mostly Germany.
There are many places in the world where it's nice to visit but not to live, I would say, Portugal is the opposite. I could realistically see myself living there.
