As some others have explained, the Iran-Israel war did not affect bitcoin much because the war did not last very long and did not have much negative impact on the economy. But if the war drags on and gets worse, it's hard to say what will happen to bitcoin at that point.

To be fair, although bitcoin has matured a lot more than it used to thanks to government adoption, institutional investment...but it is still just a speculative asset. It's not really a safe haven asset like gold, so I still think it will sell off if the war gets worse.
