i dont understand it why anybody would sell bitcoins during war? i would do the opposite especially it wont be global war just some event with crazy dictator.
Depends on the emotional sentiment and the state of the market. If it's already skittish an event like this could certainly trigger a sell-off for those who were holding positions already on the edge.
Fundamentals drive the long-term market, emotions drive the short-term. Those emotions can come from plenty of other sources then just BC related.
Wars would seem like a pretty good reason to ditch gov't currencies, especially if you think there's a risk your country's gov't could lose. Certainly, one might want to get on their food/water/porno horde, and sell BTC to do that while it's at an unprecedented high, but probably not that many...
I don't really see any emotional connection to determining whether or not to continue holding BTC, though. Doesn't everyone have Faraday cages these days??
