Hmmm, no! Thinking people make financial decisions by being stupid is the first step in making a very stupid decision. The market allows you to profit from both the rising price and the falling price. And the politics and demonstration of power are very useful to make more profit. In addition, wars are expensive and it is not yet possible to subsidize a war using only BTC.
Notwithstanding the fact that bitcoin would be a tool of war in coming years, like in end of this century or the next one. But in this era, we must make strong choices to take advantage.
