I would first move to throw off attention, then eventually move for good, visiting every now and then. I live in US now, but I would move to another country not sure which one after I win I'll make up my mind then. The inequality and political policy, taxes, insurance is killing me. People don't retire on time and college grads can't find dependable work, penalties for not having health care, to many feminist movement. So yes at the blink of an eye id move shanegrala is real I'll find it someday
If I won the lottery I would immediately buy a house or cottage somewhere Germany. I don't dislike my country but in terms of sights, history and art Europe is way more interesting than the US and the people seem to be more direct and too the point in places like Germany which I admire plus I lived in Romania for three years when I was a kid and visited Hungary so I have always had an obsession with going back and seeing the rest of Europe.
If I won the lottery I would move somewhere within the United States, I would not move to a foreign country only because all of my family is in the United States and I would not want to be so far away from them. If it weren't for my family I would gladly move to Australia.
I live in the United States currently. There are other places in the world that are more conducive to welathier individuals. I don't have a specific country in mind; there are a handful to choose from. However, life would be easier without as many taxes plus cheaper living costs. There are places, as well, that respect individual privacy better than the United States currently does.
