Ok, I’ll bite…
Originally, and the “truest” form of being a digital nomad is someone that travels enough so they don’t become tax resident in any country.
The term has been loosened more recently to include anyone that works remotely while travelling.
I pay corporation tax and personal tax in the UK but can work anywhere so fit the second definition but not the first.
To address some other misconceptions by other posters:
Not all digital nomads are cheap. I charge my clients over £1000 a day i.e. equivalent of over 40,000baht a day so don’t work very much but can spend what I want.
Not all digital nomads are “influencers” walking around with cameras. Other types include consultants (me), traders (shares, commodities, currencies), software engineers, etc.
Not all digital nomads have never had a proper job. I worked full time for over 20 years in a number of major international companies before I’d built up the experience, contacts and financial security to set up my own business.
