This is probably too abstract for many to understand so let it sink in before you react. If people are really scared of war, they are better off pulling cash out of their banks and putting it in a foreign investment account.
Not everyone is rich enough to have a foreign investment accont.
Think the average citizen who owns around $70K USD of cash, if a local war i.e. US to NK is 90% likely to break out, they would most likely immediately buy $40/50K USD worth of bitcoin, store it on a hardware wallet, whole family flees South Korea and stay at friend's or relative's place overseas place somewhere in US or Australia or China until things calm down.
Anyone can open an e-Trade account and fund it from their bank. They can later open an account in another country while they are waiting out any violence. Putting 100% of their cash savings into a volatile speculative instrument like BTC is reckless and irresponsible....as much as the reckless and irresponsible sociopaths on this forum would love to see the average unsophisticated citizen of these nations take such a risk.
Honestly that's not how I would do it if I were in that situation. Remember, if NK strikes out of the blue, they don't necessarily give you a warning for like 10 days for you to open your account and deal with your bank for 5 business days.
If I were them I would just go to BTC exchange, buy, load on hardware wallet, gone tomorrow. Opening a new account in another country usually is restricted to residence. If I'm there for a few months I won't be able to open an account overseas.
Of course everyone is entitled to their way of doing things.
Discussing how a war might push BTC price up does not mean we wish to see a war. It's just rational discussion and action reaction observation / learning / ideas exchanging.
Calling people reckless and irresponsible sociopaths is not necessary - of course again, in my opinion - you're entitled to have yours.
