If war does break out, you really don't care if Russia wins or NATO wins. The world will be a big loser.
And it doesn't matter if your wealth is in bitcoins or in gold, there is a chance that you may not be alive to enjoy it.
If the war is between Russia and the NATO, and if you are living in some other country, then the chances are that you will survive the war. Countries such as Brazil and Argentina refused to participate in the WW2. And their economy grew a lot after the war.
I think what he is saying is, the level of overwhelming force would poison the planet this time. At the very least, we would most likely get involved (well, pre Trump at least) if Russia started threatening or engaging any NATO allies with nuclear force. If we get involved, IE if Russia and the United States go to nuclear war in earnest..
It will be the most spectacular war that humans will see, and the last conflict that humans will witness.
