Can't say I could pick one without being in one long enough. I'd prefer just traveling to different countries and staying for a couple months in each, more or less depending on how much I like each.
Somewhere with a low cost of living. I make my money online so if I can cut my living cost down dramatically it'd be good. Somewhere with low taxes or taxes that aren't enforced. Friendly business and Internet laws.
Canada for sure...I don't want to go to all those other countries that have videos of people getting their heads cut off by the cartel...Sure that happens everywhere, but I think the U.S and Canada, there aren't as nearly as many
