In my personal opinion, war will affect bitocoin, but that will affect the positive direction, not the negative direction. Because when there is war, the value of the dollar will be low, people will convert the dollar into bitcoin, because bitcoin is a safe place to store and move easily.
Definitely war will affect bitcoin because war affects the life of people and their businesses as well. When people have no money for investment in bitcoin, naturally it will affect and will go down due to low trading and low investments. During the war people want to survive by any way and nobody will even think about investment in bitcoin and anything else.
