They should, and we all should, well there might be the next world war soon, since our leaders are more interested in BS and war this days, so we should have lots of bitcoin so after the war we can still have our money..
If you are concerned about war and instability an off-grid life style is much more valuable than any money in the world.
Is your dollars or bitcoins worth anything if you don't have food, water or shelter during a war?
The best example is the war in former Yugoslavia, and Bosnia in particular.
I am from Bosnia. You know, between 1992 and 1995, it was hell. For one year, I lived and survived in a city with 6,000 people without water, electricity, gasoline, medical help, civil defense, distribution service, any kind of traditional service or centralized rule.
Today, me and my family are well-prepared, I am well-armed. I have experience.
It does not matter what will happen: an earthquake, a war, a tsunami, aliens, terrorists, economic collapse, uprising. The important part is that something will happen.
