It will affect all market and not only the cryptocurrency market. No financial markets does well when there is war ongoing because all investors will be scared and prefer to hold fiats during this time because no one knows how long or impactful the war is going to be. War world does not just start but it starts from when two countries are fighting and their alliance begin to take side then the war increase and it becomes a world war. I am thinking it is about time for another war world, I do not like it but things are getting too intense recently that it might results to this. But it is better you do not sell your cryptocurrency if the market is to correct more than it has already corrected because you will not know when the bounce back is going to happen and those that have already sold will be at a lost.
