I know some of my friends who are Internet Marketers (not specifically domainers) have choosen to stay in places like Vietnam and Thailand. 1 is originally from the U.K and the other is from U.S. both have pretty much the same reasons for moving there.
They like the quality of life and super low cost of living, this enables them to build their business and being able to survive comfortably at a fraction of the cost that they would have to pay if they stayed in their home countries. The weather is awesome and both are able to get a decent Internet connection. The one in Thailand says he often meets other Internet Marketers and they share ideas and collaborate because he often visits the Punspace offices in Thailand and works from there whenever he feels like. Off course the fact that both of these guys are highly attracted to Eastern women is the cherry on top for them
I actually plan on heading down to Thailand for a few months soon this year as well.
Over years we've been roaming all over the place. Originally, I'm from the Netherlands but at some point moved to the US, Africa, different countries in Europe for years. For the moment settled in Belgium running a small offline business.
Not living from domaining atm but eventually would like it to be a big pillar for supporting the nomadic lifestyle.
