In my opinion, this issue should be discussed from a specific situation.
For example, to get a non-tourist visa in another country, then almost everywhere you need to confirm the source of funding. If you sell real estate and pay taxes, then you will have it.
For example, all European countries require that a person's money be legal and this be confirmed by documents. Therefore, if you are preparing to move to safer countries like Europe or America, then you should show the necessary legal income to get a visa.
Well, I think you're looking at it from the perspective of a non-European who wants to go to Europe. I look at it the other way around, from the perspective of a European who wants to go to another continent. There are several countries that wouldn't give you any trouble, plus you can get a tourist visa and then see what you do. The thing is, if you have bitcoin, it's much easier to hide and transport, and much harder to confiscate. It's also much more liquid, compared to having your wealth in real estate, for example.
That's why I wrote above that such cases should be considered individually.
If a European has a passive income of 2-5 thousand, then he will live well in Asia, but there are nuances, as always. If you are white, then you are rich, which means that for you the prices are 2... 5 times higher for everything, including medicine.
I've already heard many stories about white people fleeing Asia like a lion
