Economic collapse worse than the great depression as many predict. Sure, the most valuable assets will be food, fuel, ammo, and crypto. 
not cryptoammo yes, lots of ammo
if u don't have guns ur in trouble
In a true zombie apocalypse scenario I would go for vodka and fuel. As someone who's seen the collapse of the USSR, vodka is the way to go. Maybe whiskey, to account for local traditions
Guns are only required for those who already have lots of whiskey and fuel, to protect those - or if you are planning to go on the offensive.
