If the war is going to happen now, of course, most will all invest in bitcoin because there is an option where everyone will save their finances safe because the most feared thing is a war where all will think about how they are to make the wealth will not disappear.
Exactly the bitcoin currency will not be effected with it, if it will be war people will surely save their bitcoin and they will not let the market get wasted like this so I think bitcoin will not be effected by it, for me it is very important to have patience if bitcoin will get down for some time even then I wont suggest anyone to sell it because after ending of the war price of bitcoin will increase once again and this time price will be higher than our own expectation.
