WW3 and crypto currency?

I have no idea why I am writing this and anyone that has read my other posts will understand that this is the mind of a former suicidal, irrational and irresponsible individual.
With all that aside, I believe it is one of the fundamental reasons I am playing with steemit and trying in vain to understand the crypto currency phenomena.
They are, without a doubt, intent on killing a good number of us. I think anyone keeping up to date with both the main stream media and the alternatives will agree that world war three started some time ago, just short of naming it.
Today's walkout, by the Americans, British and French from the UN council was without a doubt an indication that there is now, nowhere back. They intend to pursue war with Russia and anyone that might ally with her, in some foolish notion that they have a winning strategy. I really don't think these people understand that this time the bombs will be going both ways. This time, the war wont be fought in a distant desert where all they need worry over is the constant supply of arms and a constant supply of media rhetoric to keep the public blind.
This time, it will come home. It will be our houses and our workplaces turned to rubble. It will be out infrastructure that will take decades to repair assuming anyone is left to repair it.
And what of trade? What of our continuing to barter once those first bombs drop? What use is a crypto currency that relies on the connectivity of us all to be of any use?
Yes, I understand that a wallet can be carried on a phone, a ram stick or perhaps an sd drive. But the value from that point on will be locked for everyone.
I don't post this professing to understand, nor do I post it pretending I have an answer. Perhaps someone out there does though. Perhaps the creators of this massively liberating form of finance can explain that they thought this through such a scenario. Today, very few of the global population uses or understands the wonders and freedom of crypto currencies. So of what use will it be to the few that use it?
I am going to now shuttup. This hurts my head as much as trying to get an Epson printer to work, but yes, I do feel, war has arrived and we should somehow have plans in place. The ability to carry our wealth around in such a scenario on a phone or whatever, seems a sensible idea. But is it enough?
