I don't think that war will have the effect on bitcoin that much. Bitcoiners will surely be affected but on bitcoin itself, since it's on the internet, will go on even if we're not here anymore.
The world pandemic can't destroy the system, it even highlights it, what more from a war lol. What could possibly go wrong 
? Yeah it sounds a little bit overconfident but that's what I really feel. Crypto is not like fiat which are prone from external destructions (getting burned, etc.) and inflation. Plus, mankind's technology are always moving forward. There's no such thing as like going back to primitive ways thus blockchain tech will continue to live (unless we found a new and more effective way of transacting). Maybe we are now decades away from leaving the conventional fiat system, who knows? So let's continue adopting and spreading the word. The future of this breakthrough depends on our hands.
