Mass attack happens on your country and it's suddenly at war, internet is down for vast periods, what would you rather have to hand?
$1000 cash
$1000 bitcoin
$1000 gold 

 1) Water, 2) Food 3) A gun 

 The third can get you 1 and 2.  

 That of course, but we are talking whether it's useful to have MoE you can use aka some cash 

 1000$ in bitcoin and GTFO of there 

 $500 cash to leave the country and $500 bitcoin to safely take across borders 

 Depends on so many things so the "all-round" answer will be "a mixture of all of the above". 

 no it wouldn’t. 
its one of the first things you think about and need. 

 Certainly worth keeping some on hand just in case, but for the grace of God go I (and you good folks ofc 🙏) 

 i was in albania and kosovo in 1999. 
you want currency, metals, ammo, water filtration, long storage cooking fat, dry goods, a generator, some stabilized stored gas, firewood, a bible, a radio, and patience. 

 Gosh you're interesting! Thanks for chiming in on the thread with irl experience 🙏 

 So it seems, but a working society, even without a functional power grid, will need a trade & settlement standard or more than one. Many people have gasoline powered generators or jerry cans of fuel or warehouses of long-term food.

How will you bargain for that, barring offering carnal favors? 

 I have a gun. do you? thug
I have a work to do for you, need any? bitcoiner
