The question is what kind of hyperinflation are you talking about, because there have been really drastic cases in history. The example of hyperinflation in Zimbabwe (2007/08) was so great that prices doubled every 25 hours, and the most drastic example is Hungary (1945) when prices doubled every 15 hours.

In such or similar circumstances, I think that just 1 BTC would not be enough for you no matter where you live, but far from it that would not be helpful for you to overcome the crisis more easily.
