Due to the nuclear weapon, the third world war is impossible. If it starts, all will die. Politicians understand this, therefore, no one wants it and will not allow this.
This sounds reasonable but we all know human race is umpredictable so .... but I do agree with this
The third world war is economic and media war and it is going right now.
I think crypto-currency is protection from market failures if a third world war were to happen. To be honest, I'd feel safer having my money in BTC than any financial market if a world war were to become a reality.
If a third world war really happen I think even the whole infrastructure behind the WWW will crash along with the market so now your crypto-savings will worth nothing.
In my opinion I'll be more worried about other problems that are already happening, there are uncountable ones:
- Global warming
- Starvation
- Pooverty
- Etc
