I stand for freelancing/nomad style and in a perfect world, davask will grow big enough to have different entities in the world like one in Europe and one In southwest asia (thailand, vietname, hong kong).
In that case a freelancer from Romania could tell me, I want to go in Hong Kong, and I ll say, ok I have 30h / month available in your field for that rate (rate based upon Hong Kong IT market).
If the freelancer agree, he goes, end of story (except in real life there s passport visa, personal taxes matter and so on).
Today, we are at the very beginning, I m nobody, I just have a vision and that vision is starting with romania (I actualy don t really why Romania first) and I decided to stick to romania as much as I can because if I want to be serious I need to succeed first within one community and tomorrow maybe two or three, maybe all europe and then asia but still this is a vision not a reality (yet)
Short answer the rate is based upon the country you live in, not which nationality you have except that today I work only within EU as I believe it is better to pay our taxes in our beautiful union.
