I notice always temporary effect for bitcoin , Iran Isreal war make low effect also corona virus time same think happened and crypto banned effect also similar,
and I think all effect means a chance to grab btc, If anyone think that world war is dangerous for btc then they have no knowledge about it, it is not dangerous its may give chance to grab more btc 

In my experience, the only hits that Bitcoin takes during devastating political or economic events are completely superficial and based primarily on speculative fear-selling. By which I mean "let me take my fiat's worth out of Bitcoin because the price might drop due to X thing or Y event". To me this is a buying opportunity. In the long run, Bitcoin keeps going up and due to its inherently deflationary nature (which is hard-wired), it will keep growing in value, regardless of what happens in the world (unless it is an apocalypse where everyone dies).

Use the fear, buy the coin.

Sometimes crisis didnt pose a negative impact on crypto. Like for example bitcoin during the covid19 situation, its a global threat instead bitcoin do a magnificent run. The war news impacted btc during the first week which probably due to panic selling but afterwards its gone and it immediately recovered and bounce back to a higher price.

Yeah, if majority of holders want to sell Bitcoin, it doesn't mean Bitcoin is no longer decentralized, but it's decentralized, but it just most people choose to be like that.

I think if we see many big news happen in the next six months, it won't affect Bitcoin that much because we're in bullish season.

Every major global crisis (COVID-19, Russia vs. Ukraine war) initially brought a drop in the value of Bitcoin, so that it was the first to recover compared to all other assets.

What is perhaps a more serious relationship to monitor is against the USD, where the dollar has lost 10% in value since the beginning of the year (Trump's mandate).

Not every economic crisis causes inflation, many crises cause deflation, and governments don't always print money when a crisis occurs. So bitcoin will also react differently in each crisis and bitcoin does not always grow in crises.

During the pandemic, bitcoin and stocks were severely dumped, and they only really rose when the government decided to print money and pump money to save the economy. That means the opposite would happen if the government did not decide to pump money.
Similar to war, bitcoin price also drops when there is news of war breaking out and only really increases again when there is news of a ceasefire between the two countries. But if the war drags on, causing more serious consequences for the economy, bitcoin could continue to fall instead of rise.
But in the long run, bitcoin will adapt and grow regardless of whether the war ends or not, and the war in Ukraine and Russia is an example.

The conflict between these two nations has not have any negative impact in Bitcoin price but positive impact since the war began Bitcoin price has been a bit stable, even if the price dropped at the initial stage of bombing when the Americans started supporting Israel, the Bitcoin community don't feel the impact of the war in it's price at all, instead continue to increase after the ceasefire announcement, maybe it's because Bitcoin is getting stronger globally that it will not be affected by war.

unlike the early coming up of Bitcoin, the war would have affected its price now and we would have being seeing a downward trend in price, this shows that Bitcoin is getting matured by the day and it cannot be easily shakened by small conflict among two countries, it is gradually growing to stand all huddles coming it's way, or do we say it is because its because the war between Iran-Israel has not spread to other countries or it's not strong enough to affect the global economy and market, mainly the oil sectors which is most countries means of survival, that is why we have not have the impact negatively on the price of Bitcoin.

Bitcoin doesn't care what's going on in the world. It's just that the price of Bitcoin goes down a little in these situations due to some panic sellers, but it doesn't last long. There was a little down during the war, which wasn't very big. And such a down can happen anyway. Because Bitcoin is now much more expensive and it's completely decentralized, its price depends on the pressure of buying and selling. It's normal for the price of Bitcoin to move a little when some whale investors sell or buy their Bitcoin. The war between Iran and Israel didn't seem to have as much impact on Bitcoin as it was.

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.
