price has already affect BTC on the localbitcoins in Iran, it was posted by some user in similar thread which the price reaches up to $29K. it didn't affect the whole market though. a war seem overblown though, its not like Iran will blast US but then there is a probability that Iran will be invaded as US usually do it. hope not. Iran doesn't have a local section but if there is it would be a hot big thread here in bticointalk.
In Iran, there is always presence of war and because of that many people are afraid of it and they taking there money and all of their investment out of the stock market. The impact of this in bitcoin, it would be a big question and a big thread in bitcointalk to have this kind of issue that has an involvement in bitcointalk.
