If there is a war between the US and Europe, Bitcoin will hit $1 billion
Most of the world's banks, whether big or small, are located in the US and Europe, In case of war, all banks will be closed, Which will immediately benefit Bitcoin, The price of bitcoin will increase infinitely, Many banks will quickly print dollars and euros to buy cryptocurrency quickly, This will have a huge impact on Bitcoin as there will be no other source for cross-border transactions. Remember that most of the world's banks are located in the US and Europe, while 20-25% of them operate in Asia and other regions.
What? How do you come up with this stuff? First of all there is not going to be a war between Europe and USA. Why should there a war between western countries when the tensions are high between the middle east, China and Russia? There are so many big wars more likely than a USA vs Europe war. Secondly, why would central banks be buying bitcoins and other cryptos? It might be the case that the people lose all their trust in Euros and Dollars and would start buying cryptos. But once the price sky rockets I don't think it's going to keep attracting more investors. Also a war is never a permanent situation, eventually the war will be over and things will go back to normal. A price of 1bn for BTC seems unrealistic, even with high inflation for a few years.
