You know I think with the world war rumors spurring up , they will soon be very important commodity , because in the time of war and famine one should understand the normal governmental body is set to collapse , so I think soon enough the bitcoins and other cryptocurrencies are going to be super important and the way it is maintaining it's value above 7k shows that in the future we can see a pretty big move .
With this development of events that you are talking about, you really need an alternative for fiat money and in this situation, cryptocurrency can really replace all national currencies if the whole world is drawn into a war. But you need to take into account the fact that in very difficult situations in the world even the Internet can cease to exist and then the use of cryptocurrencies will be impossible.
Undoubtedly, if Bitcoin is the only international payment instrument and its demand in the world increases, then it is quite possible that its price will rise tens of thousands of times.
