When World War 3 came, I thought Crypto in general and Bitcoin in particular were still alive and even stronger.  Think about it, when war comes, bombs and bombs will destroy our physical possessions.  Houses, gold, and cash can all be lost.  But with cryptocurrency, it is non-physical and will never be affected, it even helps people retain assets when people just buy the coin and hold it in the cold wallets.
Cryptocurrency is having a very positive effect on the general economy and it is really a great solution to reduce inflation.  Therefore, it never dies and can only thrive when negative economic or political events happen.
