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.
