Hey. You can invest in any type of money you want. I still like paper money, silver and/or gold ... stuff you can touch. I believe if China, Iran. N Korea or Russia ever think they could get away with presenting us with a nuclear EMP all that electronic money and pretty much all electronics will disappear in a flash.
You read too much doom porn. An EMP “might” take out a city. But not the world. The blockchain is distributed to avoid exactly this.
Plus, an EMP would trigger a nuclear war—and no money would be worth anything if that happened.
