I have long been terrified of something shaped a bit like this. Here in the US we already treat most workers like absolute garbage. If one day the Average Joe wakes up and finds that all his money is merely some electronic scribbles in a database which have mysteriously gone missing, the social unrest is probably something that most people on this site couldn't even conceptualize of. Today it's Zelle, but what happen…
Also HN will probably get upset for me saying this but a few grams of gold or silver or other goods easily tradeable like whiskey or ammo never hurt anybody and might buy you a pig to slaughter or something.
