The Iran and Israel war is not the first war since the existence of bitcoin; there have been several wars before now. Russia and Ukraine have been fighting long before now, and it did nothing to bitcoin.
Apart from wars, there have been terrible occurrences like COVID-19, and it did nothing to bitcoin. Bitcoin is very decentralized, and it is here to stay. People who don’t understand the value of bitcoin would always think otherwise when there is war or some occurrence. Bitcoin has gone through many tough times in the world, but it is still doing well and gaining more adoption.
It would be incorrect to say that wars or terrible events like covid19 do not affect bitcoin. Bitcoin is even severely affected but it is all short and medium term impact.
If I remember correctly, when the Russia-Ukraine war broke out, bitcoin was dumped and at one point dropped below $15k in late 2022 before recovering and growing again in 2023. Likewise Bitcoin also dumped badly when covid paralyzed the world economy, and it only grew when governments decided to pump money to save the economy.
It can be said that bitcoin is always affected whenever the economy is unstable but over time, it will recover and increase in price again.
