Bitcoin is absolutely not a cryptocurrency or currency that could be associated with any war, if we mean a war on a large scale, such as what is happening now between Russia and Ukraine, or a criminal war.
Bitcoin is not suitable for transactions that need to be anonymous, for this purpose Monero is used. In general, cryptocurrencies, including Bitcoin, are not perceived even by the police as a criminal phenomenon. Cash contains much more crime.
Monero is great for anonymous transactions. It has proven its effectiveness more than once. This is the path all other projects should take, and not grovel under government agencies that pry into private life, hiding behind a beautiful pretext about security and other nonsense.
During war, all methods of saving money are good. Crypto is one of such options. It is enough to keep the seed phrase and password in mind so that you have access to the wallet just in case.
