you don't need to subdivide it. just sell your gold coin or bar at the pawn shop. then go spend your money.
In a scenario where it costs $1 million for a loaf of bread, how many wheelbarrows will you need to cart around the cash you receive for selling a bar of gold? And you better spend all that cash today, because by next week it will have lost another 90% of its value.
i'm sure that every pawn shop that buys gold has some type of device like this. it's not a big cost at all.
So now you are entirely dependent on a third party who can price gouge you. And who is to say that in an economic collapse pawn shops will even still exist or operate or want to buy gold? Not to mention carrying around wheelbarrows full of cash as above, since who knows if internet banking will still be working. Bitcoin solves all of this.
well, if you can find someone that has a computer connected to the internet and who understand how bitcoin works, maybe it is.
Using a wallet such as Electrum on your phone is good enough for most people.
if the dollar went to 0, they might make it illegal to buy other fiat currencies or even bitcoin.
You forget that I lost all my bitcoin in a boating accident!
