Bitcoin is backed by mathematics. What's gold backed by?
Gold's value is backed by around 4000 years of history. I like bitcoin and its potential, but let's not let hubris get out of hand.
I'm just poking some fun into the arbitrary "this currency is backed by X..." discussion. I enjoy asking goldbugs who are critical of a digital what they think their gold is "backed by." Hopefully it gets them thinking about what exactly makes currency valuable. I also stack PMs, so I can totally understand why it's tough to see the same level of value in a digital currency.
