I make 6 figures in tech. No dependable and I actually save when abroad because I go to cheaper destination than home + sublet my place. I’ve been able to save a considerable part of my income while doing so. I travel on and off (it’s hard to sustain nomading constantly with a demanding job + I enjoy going to the office once in a while).

1000$ sounds like someone who is self-employed without sufficient clients, very entry-level / part-time and/or coming from a country with low waves compared to Western Europe / North America.

Lots of people call themselves digital nomads while, in theory, they quit their job and live off savings / small gigs then they return home when broke. Some are using lower costs of living in Asia, for example, to bootstrap a business idea. It’s very different than the employed nomads or settled entrepreneurs and the latter usually don’t travel full time or super fast - it’s unsustainable with the need to be productive
