As I read before, wars and crises often lead governments to print more money or run large deficits, triggering inflation and currency devaluation. Bitcoin’s fixed supply can make it appealing as a store of value resistant to inflation, increasing demand, and driving its price up. Therefore, not all the time do wars and crisis bring Bitcoin prices down.
It is true that wars and crises often cause governments to print more money, but it depends. Depending on how the world treats bitcoin, if the world still doesn't see it as a safe haven, they just see it as a speculative asset, then it will likely dump instead of rise. That is why it is often dumped during times of war or geopolitical instability.
But in the long run, what you say is true because regardless of whether wars and crises end or not, people and economies will find ways to adapt. That is why the war between Russia and Ukraine continues, inflation remains high, causing the Fed to not lower interest rates, but the price of bitcoin and other speculative assets continues to rise.
