Yeah if there is a full on apocalypse then I doubt money/bitcoin will be a major concern somehow.
Even guns, they weigh a lot, they need parts and ammo.... and if you are a hoarder/prepper then unless you can defend your stash then you are just collecting shit for others to steal.
One should make a suit made from the carcass of a deer or a bear, then sharpen up your bow and arrow making and firing skills, become a roaming hunter gatherer, oh and also make sure you have raided your local outlets for all of the fish antibiotics you can get your hands on... that shit is exactly the same as human antibiotics, thomas labs fishmox forte = amoxicillin etc etc you can get that shit in walmart or a local shop that sells fish tank products, you could barter antibiotics, be like some sort of witch doctor for the next lost generation.
Yeah thats the ticket, don your animal suit, sharpen your arrows, and become a roaming antibiotics barter man...
...........of course once you are established enough you could settle down and start a women farm, that would be the retirement dream...
awhh I can't wait.
