If dollar prices fall, then the conversion might change. Worst case scenario, people from both countries would start buying cryptos in the event that a war devastates their economies and try to leave and maybe just encash elsewhere.
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.
Wow, $29k! I think that's even higher than the ath in 2017. But then again, if they are really afraid that they might lose it all if they ever get invaded, might as well lose a bit buying at that price and salvage what's left.
